Discrimination power of a quantum detector
Christoph Hirche, Masahito Hayashi, Emilio Bagan +1
We investigate the ability of a quantum measurement device to discriminate two states or, generically, two hypothesis. In full generality, the measurement can be performed a number…
Efficient unitary designs with nearly time-independent Hamiltonian dynamics
Yoshifumi Nakata, Christoph Hirche, Masato Koashi +1
We provide new constructions of unitary -designs for general on one qudit and qubits, and propose a design Hamiltonian, a random Hamiltonian of which dynamics always for…
Schur complement inequalities for covariance matrices and monogamy of quantum correlations
Ludovico Lami, Christoph Hirche, Gerardo Adesso +1
We derive fundamental constraints for the Schur complement of positive matrices, which provide an operator strengthening to recently established information inequalities for quantu…
