Error-tolerant secure key leasing for quantum decryption keys in public-key encryption
Duo Xu, Yuki Takeuchi
We propose the first error-tolerant secure key leasing (SKL) for public-key encryption. As with SKL in prior works, our protocol consists of a lessor and lessee. In the protocol, t…
Anonymous estimation of intensity distribution of magnetic fields with quantum sensing network
Hiroto Kasai, Yuki Takeuchi, Yuichiro Matsuzaki +1
A quantum sensing network is used to simultaneously detect and measure physical quantities, such as magnetic fields, at different locations. However, there is a risk that the measu…
Simplest fidelity-estimation method for graph states with depolarizing noise
Tomonori Tanizawa, Yuki Takeuchi, Shion Yamashika +2
Graph states are entangled states useful for several quantum information processing tasks such as measurement-based quantum computation and quantum metrology. As the size of graph…
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…
Passive verification protocol for thermal graph states
Kazuki Akimoto, Shunji Tsuchiya, Ryosuke Yoshii +1
Graph states are entangled resource states for universal measurement-based quantum computation. Although matter qubits such as superconducting circuits and trapped ions are promisi…
