Gauge dependence of the Aharonov-Bohm phase in a quantum electrodynamics framework
A. Hayashi
The Aharonov-Bohm (AB) phase is usually associated with a line integral of the electromagnetic vector potential generated by an external current source, such as a solenoid. Accordi…
Physical symmetries and gauge choices in the Landau problem
Masashi Wakamatsu, Akihisa Hayashi
Due to a special nature of the Landau problem, in which the magnetic field is uniformly spreading over the whole two-dimensional plane, there necessarily exist three conserved quan…
Simple criterion for local distinguishability of generalized Bell states in prime dimension
T. Hashimoto, M. Horibe, A. Hayashi
Local distinguishability of sets of generalized Bell states (GBSs) is investigated. We first clarify the conditions such that a set of GBSs can be locally transformed to a certain…
Quantum-state comparison and discrimination
A. Hayashi, T. Hashimoto, M. Horibe
We investigate the performance of discrimination strategy in the comparison task of known quantum states. In the discrimination strategy, one infers whether or not two quantum syst…
Minimum uncertainty states and completeness of non-negative quasi probability of finite-dimensional quantum systems
T. Hashimoto, A. Hayashi, M. Horibe
We construct minimum-uncertainty states and a non-negative quasi probability distribution for quantum systems on a finite-dimensional space. We reexamine the theorem of Massar and…
A Non-Interactive Quantum Bit Commitment Scheme that Exploits the Computational Hardness of Quantum State Distinction
Tomoyuki Yamakami
We propose an efficient quantum protocol performing quantum bit commitment, which is a simple cryptographic primitive involved with two parties, called a committer and a verifier.…
