One parameter generalization of BW inequality and its application to open quantum dynamics
Dariusz Chruściński, Gen Kimura, Hiromichi Ohno +1
In this paper, we introduce a one parameter generalization of the famous Böttcher-Wenzel (BW) inequality in terms of a -deformed commutator. For matrices and $B…
Construction of general symmetric-informationally-complete-positive-operator-valued measures by using a complete orthogonal basis
Masakazu Yoshida, Gen Kimura
A general symmetric-informationally-complete (GSIC)-positive-operator-valued measure (POVM) is known to provide an optimal quantum state tomography among minimal IC POVMs with a fi…
Trade-off relations between measurement dependence and hidden information for factorizable hidden variable models
Ryo Takakura, Kei Morisue, Issei Watanabe +1
The Bell theorem is explored in terms of a trade-off relation between underlying assumptions within the hidden variable model framework. In this paper, recognizing the incorporatio…
Relaxed Bell inequalities as a trade-off relation between measurement dependence and hiddenness
Gen Kimura, Yugo Susuki, Kei Morisue
Quantum correlations that violate the Bell inequality cannot be explained by any (measurement independent) local hidden variable theory. However, the violation only implies incompa…
Bounding the Frobenius norm of a q-deformed commutator
Dariusz Chruściński, Gen Kimura, Hiromichi Ohno +1
For two complex matrices and , we define the -deformed commutator as for a real parameter . In this paper, we investigate a gen…
Constraints for the spectra of generators of quantum dynamical semigroups
Dariusz Chruscinski, Ryohei Fujii, Gen Kimura +1
Motivated by a spectral analysis of the generator of completely positive trace-preserving semigroup, we analyze a real functional $$ A,B \in M_n(\mathbb{C}) \to r(A,B) = \frac{1}{2…
