DOI: 10.1002/andp.202000462
Abstract: To quantify the entanglement is one of the most important topics in quantum entanglement theory. In [arXiv: 2006.12408], the authors proposed a method to build a measure from the orginal domain to a larger one.… read more here.

DOI: 10.1007/s10773-019-04200-w
Abstract: We provide an expression for the measure of coherence of quantum pure states, which is obtained by quantifying the deviation or distance between the measured state and the maximally coherent states in the same Hilbert… read more here.

DOI: 10.1080/09500340.2017.1382592
Abstract: Abstract We investigate the optimum strategy for state discrimination of two pure states when the probability of inconclusive answers is fixed. By varying a given rate of inconclusive probabilities, the strategy optimally interpolates between Unambiguous… read more here.

DOI: 10.1103/physreva.100.022320
Abstract: The states of three-qubit systems split into two inequivalent types of genuine tripartite entanglement, namely the Greenberger-Horne-Zeilinger (GHZ) type and the $W$ type. A state belonging to one of these classes can be stochastically transformed… read more here.

DOI: 10.1103/physreva.100.032316
Abstract: We propose practical and efficient protocols for verifying bipartite pure states for any finite dimension, which can also be applied to fidelity estimation. Our protocols are based on adaptive local projective measurements with either one-way… read more here.

DOI: 10.1103/physreva.107.042411
Abstract: We investigate the relation between the amount of entanglement localized on a chosen subsystem of a multi-qubit system via local measurements on the rest of the system, and the bipartite entanglement that is lost during… read more here.

DOI: 10.1103/physreve.105.064112
Abstract: Fluctuation theorems are cornerstones of modern statistical mechanics and their standard derivations routinely rely on the crucial assumption of a canonical equilibrium state. Yet rigorous derivations of certain fluctuation theorems for microcanonical states and pure… read more here.

DOI: 10.12693/aphyspola.139.164
Abstract: The article undertakes the problem of pure state estimation from projective measurements based on photon counting. Two generic frames for qubit tomography are considered -- one composed of the elements of the SIC-POVM and the… read more here.
