Optimal discrimination of optical coherent states cannot always be realized by interfering with coherent light, photon counting, and feedback
Kenji Nakahira, Kentaro Kato, Tsuyoshi Sasaki Usuda
It is well known that a minimum error quantum measurement for arbitrary binary optical coherent states can be realized by a receiver that comprises interfering with a coherent refe…
Generalized bipartite quantum state discrimination problems with sequential measurements
Kenji Nakahira, Kentaro Kato, Tsuyoshi Sasaki Usuda
We investigate an optimization problem of finding quantum sequential measurements, which forms a wide class of state discrimination problems with the restriction that only sequenti…
Relationships between multiple zeta values of depths 2 and 3 and period polynomials
Ding Ma, Koji Tasaka
Some combinatorial aspects of relations between multiple zeta values of depths 2 and 3 and period polynomials are discussed.
Cyclotomic analogues of finite multiple zeta values
Henrik Bachmann, Yoshihiro Takeyama, Koji Tasaka
We introduce the notion of finite multiple harmonic q-series at a primitive root of unity and show that these specialize to the finite multiple zeta value (FMZV) and the symmetrize…
