Phase-error estimation for quantum key distribution with leaky receivers
Álvaro Navarrete, Margarida Pereira, Guillermo Currás-Lorenzo +3
Practical quantum key distribution (QKD) receivers may leak information about their measurement outcomes and settings to the channel (e.g., through detector backflashes or back-ref…
Deterministic QKD source robust against side-channel attacks
Kiyoshi Tamaki, Marcos Curty, Akihiro Mizutani +2
The paper proposes a deterministic quantum key distribution source that is intrinsically resistant to side‑channel attacks, eliminating the need for post‑selection or perfect extin…
Rewindable Quantum Computation and Its Equivalence to Cloning and Adaptive Postselection
Ryo Hiromasa, Akihiro Mizutani, Yuki Takeuchi +1
We define rewinding operators that invert quantum measurements. Then, we define complexity classes , , and as sets of decision problems s…
Loss-tolerant quantum key distribution with detection efficiency mismatch
Alessandro Marcomini, Akihiro Mizutani, Fadri Grünenfelder +2
Current implementations of quantum key distribution (QKD) typically rely on prepare-and-measure (P&M) schemes. Unfortunately, these implementations are not completely secure, unles…
Differential-phase-shift QKD with practical Mach-Zehnder interferometer
Akihiro Mizutani, Masanori Terashita, Junya Matsubayashi +4
Differential-phase-shift (DPS) quantum key distribution stands as a promising protocol due to its simple implementation, which can be realized with a train of coherent pulses and a…
Tight scaling of key rate for differential-phase-shift quantum key distribution
Akihiro Mizutani, Toyohiro Tsurumaru
The performance of quantum key distribution (QKD) protocols is evaluated based on the ease of implementation and key generation rate. Among major protocols, the differential-phase-…
