A point-to-point long-distance quantum key distribution (QKD) over a distance of 1,002 km has been achieved by scientists from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), and their collaborators from Tsinghua University, Jinan Institute of Quantum Technology, and Shanghai Institute of Microsystem and Information Technology (SIMIT), CAS. This milestone not only sets a new world record for non-relay QKD but also provides a solution for high-speed intercity quantum communication. The results were published in Physical Review Letters on May 25th.
QKD is based on the principles of quantum mechanics and enables secure key distribution between two remote parties. When combined with the "one-time pad" encryption method, it can achieve the highest level of security for confidential communication. However, the distance of QKD has been limited by factors such as the channel loss and system noise.
The twin-field QKD (TF-QKD) using sending-or-not-sending (SNS) protocol was demonstrated in the experiment, improving the relation between the key rate and channel transmittance from a linear η to its square root η. Therefore, it can achieve a much longer secure distance than traditional QKD protocols.
To achieve long-distance QKD, the research team collaborated with Yangtze Optical Fiber and Cable Joint Stock Limited Company (YOFC) and used ultra-low-loss fiber based on pure silica core technology, which achieved a maximum attenuation of 0.16 dB/km. SIMIT developed ultra-low-noise superconducting single-photon detectors.
By implementing multiple filters at temperatures of 40 K and 2.2 K to suppress dark counts caused by thermal radiation, the noise of the single-photon detectors was reduced to around 0.02 cps. Furthermore, the team also developed a dual-band phase estimation scheme to avoid the spontaneous Raman scattering noise, reducing the system noise to below 0.01 Hz.
Based on the aforementioned technological developments, the team achieved TF-QKD over a record distance of 1,002 km, with a key rate of 0.0034 bps. This work not only verifies the feasibility of the SNS-TF-QKD scheme at extremely long distances but also demonstrates that this protocol can achieve high key rates in many practical scenarios.
The success of this study holds significant implications for the advancement of secure quantum communication. It opens up new possibilities for long-distance quantum key distribution and paves the way for the realization of high-speed intercity quantum communication networks.

L'Infrastruttura europea di comunicazione quantica
Al via la prima rete quantistica europea. Per la prima volta Italia, Slovenia e Croazia sono state connesse stabilmente tramite EuroQci, l’innovativa rete europea per le comunicazioni quantistiche, pilastro della nuova strategia di sicurezza informatica dell'Unione.
Italia, Slovenia e Croazia sono i primi tre paesi europei ad essere stati collegati tramite EuroQci, l’innovativa rete europea per le comunicazioni quantistiche, a cui l’Italia partecipa con il supporto del Consiglio nazionale delle ricerche (Cnr) e delle università di Firenze e Trieste. Lo riporta la rivista Advanced quantum technologies, che ha pubblicato i risultati della prima dimostrazione pubblica di comunicazione crittografata del programma, effettuata con successo durante la riunione dei ministri del G20 sulla digitalizzazione, svoltosi a Trieste nel 2021.
A giugno 2019, i 27 stati membri dell’Unione europea hanno aderito al progetto EuroQCI, firmando la Dichiarazione sull’infrastruttura europea di comunicazione quantistica. L’obiettivo è di rafforzare la protezione delle istituzioni governative europee, dei loro centri dati, degli ospedali, delle reti energetiche e altro ancora, diventando uno dei pilastri principali della nuova strategia di sicurezza informatica dell'Unione per i prossimi decenni.
EuroQci è coordinata dalla Commissione europea per i collegamenti terrestri in fibra ottica e dall’Agenzia spaziale europea (Esa) per i collegamenti satellitari. Il primo servizio attivato è la Quantum key distribution (Qkd), un protocollo in grado di fornire comunicazioni di dati sicure grazie alle leggi della fisica quantistica, proteggendo da potenziali attacchi. Come sottolinea il comunicato diffuso dal Cnr, qualunque tentativo di intercettare la chiave distribuita attraverso Qkd lascerebbe una traccia usabile per rilevare l'intrusione e di agire contro eventuali minacce.
Dopo la prima dimostrazione pubblica del collegamento Qkd, l’iniziativa EuroQci ha preso ufficialmente il via, collegando stabilmente Trieste a Fiume, con un unico collegamento in fibra di 100 chilometri, e a Lubiana, tramite un trusted node a Postumia, cioè un nodo di ripetizione costituito da una coppia ricevitore-trasmettitore Qkd, in cui i fotoni vengono letti fino a ricostruire la chiave, che poi viene trasmessa sul collegamento adiacente. In questo modo, un link Qkd può essere collegato al successivo per realizzare una rete estesa.
La rete è realizzata grazie all'università di Trieste, al gruppo Quantum communications dell'Istituto nazionale di ottica (Ino) del Cnr di Firenze, alla Technical university of Denmark (Dtu) e all’università di Firenze nell'ambito del “Quantum FVG”, progetto finanziato dalla Regione autonoma Friuli Venezia Giulia, dalla facoltà di Matematica e fisica dell'università di Lubiana, dall'Istituto Ruder Bošković e dalla facoltà di Scienze dei trasporti e del traffico di Zagabria. La realizzazione tecnica è stata curata da Qti srl, spin-off del Cnr e società partecipata Telsy, con il supporto di Tim, Sparkle, Telekom Slovenije, Oiv - Digital signals and networks, Stelkom e Lightnet che hanno fornito l’infrastruttura in fibra ottica.

Bitcoin in a Post Quantum Cryptographic World
Quantum computing, once a theoretical concept, is now an impending reality. The development of quantum computers poses significant threats to the security of many cryptographic systems, including Bitcoin. Cryptographic algorithms currently used in Bitcoin and similar systems may become vulnerable to quantum computing attacks, leading to potential disruptions in the blockchain ecosystem. The question arises: What will be the fate of Bitcoin in a post-quantum cryptographic world?
Bitcoin relies on two cryptographic principles: the Elliptic Curve Digital Signature Algorithm (ECDSA) and the SHA-256 hashing function. The ECDSA is used for signing transactions, which verifies the rightful owner of the Bitcoin. On the other hand, the SHA-256 hashing function is used for proof-of-work mechanism, which prevents double-spending. Both principles are expected to become vulnerable in the face of powerful quantum computers.
Quantum Threat to Bitcoin
Quantum computers, due to their inherent nature of superposition and entanglement, can process information on a scale far beyond the capability of classical computers. Shor's Algorithm, a quantum algorithm for factoring integers, could potentially break the ECDSA by deriving the private key from the public key, something that is computationally infeasible with current computing technology. Grover's Algorithm, another quantum algorithm, can significantly speed up the process of finding a nonce, thus jeopardizing the proof-of-work mechanism.
Post-Quantum Cryptography
In a post-quantum world, Bitcoin and similar systems must adapt to maintain their security. This is where post-quantum cryptography (PQC) enters the scene. PQC refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against an attack by a quantum computer. These algorithms provide a promising direction for securing Bitcoin and other cryptocurrencies against the quantum threat.
Bitcoin in the Post Quantum World
Adopting a quantum-resistant algorithm is a potential solution to the quantum threat. Bitcoin could potentially transition to a quantum-resistant cryptographic algorithm via a hard fork, a radical change to the blockchain protocol that makes previously invalid blocks/transactions valid (or vice-versa). Such a transition would require a complete consensus in the Bitcoin community, a notoriously difficult achievement given the decentralized nature of the platform.
Moreover, the Bitcoin protocol can be updated with quantum-resistant signature schemes like the Lattice-based, Code-based, Multivariate polynomial, or Hash-based cryptography. These cryptosystems are believed to withstand quantum attacks even with the implementation of Shor's Algorithm.
Additionally, Bitcoin could integrate quantum key distribution (QKD), a secure communication method using a cryptographic protocol involving components of quantum mechanics. It enables two parties to produce a shared random secret key known only to them, which can be used to encrypt and decrypt messages.
Conclusion
In conclusion, the advent of quantum computers does indeed pose a threat to Bitcoin's security. However, with the development of post-quantum cryptography, there are potential solutions to this problem. The future of Bitcoin in a post-quantum world is likely to depend on how quickly and effectively these new cryptographic methods can be implemented. The key is to be prepared and proactive to ensure the longevity of Bitcoin and other cryptocurrencies in the face of this new quantum era.
While the quantum threat may seem daunting, it also presents an opportunity - an opportunity to improve, to innovate, and to adapt. After all, the essence of survival lies in the ability to adapt to change. In the end, Bitcoin, like life, will find a way.

QKD -- Hiatus
Hey, my lovely QKD readers! As I mentioned in the notes on my last chapter, I'll be taking a hiatus as production season ramps up for the play I'm in. I'm also struggling with Chapter 9, so this gives me a chance to reorient myself.
I plan to be back by mid-April, but it may be sooner or later, depending on how life works out.
But stay tuned, I may post some one-shots (AU and otherwise) during the hiatus to keep my writing gears greased.
Thanks to those of you who have been so faithful to read and comment on my story, you mean so, so much to me!!
Until next time <3

Building Secure Communication Networks of the Future
While it may sound like science fiction, a quantum internet could one day exist. Researchers are working to build ultra-secure communication networks that would use the laws of quantum physics to transmit information in an unhackable way. But what is a quantum internet, and how does it work?
Efforts to bring about a quantum network are underway in many places around the world. This year, the United States published its first Quantum Internet Blueprint, laying out a roadmap for making the network a reality over the next decade.
In a quantum network, bits of information are encoded as quantum states. This allows a great deal of information to be transmitted over a very short distance, resulting in very high data rates and extremely secure communications. However, in order to reach practical performance levels, the different components of the network must be carefully coordinated and synchronized. This is a difficult task, and it requires a very careful design of the entire system.
A key challenge is that quantum state information is subject to “decoherence,” an effect that causes the quantum states to lose their quantum properties tech ogle over long distances. A well-designed network will mitigate this effect, but it is challenging to achieve a fully robust, scalable design. This is why a good design process is crucial for the success of any quantum network.
The research community is working to overcome these challenges and develop a scalable design. The most significant challenge is the creation of long-distance entanglement, which is necessary for quantum communication. This is achieved by forming a pair of quantum particles, such as photons, that are linked together. These entangled particles can then be separated and their separate information independently transmitted to different locations.
Once these entangled pairs of photons are sent, they can be reunited and their information combined to form a single, complete bit of data. This process is known as “quantum teleportation.”
Despite the challenges, experimental progress has been swift in recent years. Scientists have already built rudimentary quantum communication links, with the latest link between DOE Argonne National Laboratory and University of Chicago spanning 52 miles. This will be expanded to connect 17 DOE National Laboratories over the coming decade, establishing a working prototype of a quantum internet that could be used for advanced applications such as secure cloud computing.
The earliest practical applications will likely be in areas such as quantum key distribution (QKD). By using QKD, distant participants can share an encryption key that is protected by the immutable principles of quantum technology news mechanics. This would ensure that eavesdroppers can’t intercept the key or decipher the message, even if they are listening in on one end of the conversation.
As the research continues, it’s important that scientists focus on what matters most. ESnet, with its experience in connecting testbeds and supporting end-to-end testing, can play an instrumental role in helping researchers identify the most promising techniques and guide their experiments to a successful outcome.

new ask game send me a 🌻 and ill just tell you whatever the fuck i want
((1. after using the new post editor vs the old post editor and switching back and forth between them on my blogs, i gotta say! old post editor fucks
((though the new post editor has a TON of QoL changes that elevator to more of an equal status
((like, being able to tell when a special thing like italics starts and stops is a fucking amazing feature and i wish it was on the old post editor
((or being able to edit tags, or being able to make text BIG or BIGGER, or things like that
((but running with the old post editor for a while on the qkd blog has brought about some really funny/interesting bits!
((this gimmick is really fun. it feels like ive been running the blog for months but its only been less than one. i love that blog
((2. speaking of--if things havent been obvious so far, then lemme say it outright right now
((i am going through the entirety of poppy's story on that blog, pre-poppy to... an ending, of sorts
((which means events will just sort of happen over there, in slight congruence to when they happened in poppy. such aaaaaaaaas
((this whole thing! in fact, it's happening in a thread right now~.
((at the end of arcs/events i plan on tagging all of the previous posts that took place in that event as like... a relevant tag, so that i might chrono them and maybe my things can be read as a sort of story. this is... going to be a pain. but! i am incredibly committed to all of this now. i am excited. things are going to fucking happen.
((uh, sorry for all the kit-blog talk. i am just kind of. really excited for that blog! i have this base guideline already set for me to follow and i get to explore how this MF goes through the entirety of what-we-know in poppy. including somee other things that are at play because of the nature of just. knowing more than my characters know
((having characters like lila and chicadino just making funni appearances this early into the story is just so much fun you dont even know.
((sidenote bonus thing but i really want chicadino to interact with @/fallen-symphony crew because like. he's a villain, with an outrageous lucky star at that. it'd be REALLY FUCKING FUN. i wanna do arthur interactions IN GENERAL, REALLY
((but alas. there is literally no conceivable way i could approach first about this without majorly breaking things and his knowledge on the world rn. his little birdy would not know about multiverse theory (yet).
((3. im thinking of like, making some slight changes on this blog? to save myself the sanity? but i dont know how.
((i aint stoppin' playing carol--i love this dumbass just as much as i love kit
((but man oh man i look at the amount of threads i have on here versus the amount i have on kit and its like
((well of course im over there more--i can actually count the things i have to do over there. and one of them finished! and another one has a finish line i can conceivably get to! cant say much for the other threads but im sure a finish line can be gotten.
((i do feel bad that activity has waned over here. again, carol has a lot of shit still happening and a lot of things i still havent properly addressed. the ideas are in my head, its just
((pen has to touch paper, y'know? that's it, that's all it is. i dont wanna take on new threads here because i get this anxiety that its just gonna stall me from actually doing things. i already have important threads that do need to get finished that i simply havent touched in like, weeks.
((maybe i just need to find these threads and hyper focus on them and then like, one or two more things. have something that can keep my sanity, well, sane. because otherwise it is going to be very hard for me to keep up things over here.
((i pray that this same issue doesnt occur on qkd. ive been thinking about implementing a thread cap of sorts, just so the overwhelming thing doesnt happen.
((still need to think about things tho. my mind is being RACKED as of current.))
