Tight finite-key security for twin-field quantum key distribution
Guillermo Currás-Lorenzo, Alvaro Navarrete, Koji Azuma +3
Quantum key distribution (QKD) offers a reliable solution to communication problems that require long-term data security. For its widespread use, however, the rate and reach of QKD…
Improvements on "Secure multi-party quantum summation based on quantum Fourier transform"
Cai Zhang, Mohsen Razavi, Zhewei Sun +1
Recently, a quantum multi-party summation protocol based on the quantum Fourier transform has been proposed [Quantum Inf Process 17: 129, 2018]. The protocol claims to be secure ag…
Multi-party quantum summation based on quantum teleportation
Cai Zhang, Mohsen Razavi, Zhiwei Sun +2
We present a secure multi-party quantum summation protocol based on quantum teleportation, in which a malicious, but non-collusive, third party (TP) helps compute the summation. In…
Absolutely maximally entangled states, quantum maximum distance separable codes, and quantum repeaters
Daniel Alsina, Mohsen Razavi
We extend the relation between absolutely maximally entangled (AME) states and quantum maximum distance separable (QMDS) codes by constructing whole families of QMDS codes from the…
A trusted-node-free eight-user metropolitan quantum communication network
Siddarth Koduru Joshi, Djeylan Aktas, Sören Wengerowsky +12
Quantum communication is rapidly gaining popularity due to its high security and technological maturity. However, most implementations are limited to just two communicating parties…
Advances in Quantum Cryptography
S. Pirandola, U. L. Andersen, L. Banchi +15
Quantum cryptography is arguably the fastest growing area in quantum information science. Novel theoretical protocols are designed on a regular basis, security proofs are constantl…
