Security loophole in error verification in quantum key distribution
Toyohiro Tsurumaru, Akihiro Mizutani, Toshihiko Sasaki
The security of quantum key distribution (QKD) is evaluated based on the secrecy of Alice's key and the correctness of the keys held by Alice and Bob. A practical method for ensuri…
Indistinguishability between quantum randomness and pseudo-randomness under efficiently calculable randomness measures
Toyohiro Tsurumaru, Tsubasa Ichikawa, Yosuke Takubo +3
We present a no-go theorem for the distinguishability between quantum random numbers (i.e., random numbers generated quantum mechanically) and pseudo-random numbers (i.e., random n…
Finite-key security analysis of differential-phase-shift quantum key distribution
Akihiro Mizutani, Yuki Takeuchi, Kiyoshi Tamaki
Differential-phase-shift (DPS) quantum key distribution (QKD) is one of the major QKD protocols that can be implemented with a simple setup using a laser source and a passive detec…
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…
Long-term secure distributed storage using quantum key distribution network with third-party verification
Mikio Fujiwara, Ryo Nojima, Toyohiro Tsurumaru +3
The quantum key distribution network with Vernam's One Time Pad encryption and secret sharing are powerful security tools to realize an information theoretically secure distributed…
Computational self-testing for entangled magic states
Akihiro Mizutani, Yuki Takeuchi, Ryo Hiromasa +2
In the seminal paper [Metger and Vidick, Quantum '21], they proposed a computational self-testing protocol for Bell states in a single quantum device. Their protocol relies on the…
