Reply to the Comment by A.J. Leggett and Anupam Garg [PDF]
, 2010 In their comment[1] on our Letter [arXiv:0907.0767], Leggett and Garg claim that they have introduced in their original paper (LG1) a dependence on measurement times.

Disturbance-based measure of macroscopic coherence
New Journal of Physics, 2017 We propose a measure of macroscopic coherence based on the degree of disturbance caused by a coarse-grained measurement. Based on our measure, we point out that recently proposed criteria of macroscopic coherence may lead to inconsistent results when ...

Understanding quantum mechanics: a review and synthesis in precise language
Open Physics, 2019 This review, of the understanding of quantum mechanics, is broad in scope, and aims to reflect enough of the literature to be representative of the current state of the subject.

Measurement-induced nonlocality based on the trace norm
New Journal of Physics, 2015 Nonlocality is one unique property of quantum mechanics that differs from the classical world. One of its quantifications can be properly described as the maximum global effect caused by locally invariant measurements, known as measurement-induced ...

Expanded Quantum Cryptographic Entangling Probe
, 2005 The paper [Howard E. Brandt, "Quantum Cryptographic Entangling Probe," Phys. Rev. A 71, 042312 (2005)] is generalized to include the full range of error rates for the projectively measured quantum cryptographic entangling probe.Comment: 4 ...

Qubit state tomography in a superconducting circuit via weak measurements
New Journal of Physics, 2017 In this work we present a study on a new scheme for measuring the qubit state in a circuit quantum electrodynamics (QED) system, based on weak measurement and the concept of weak value. To be applicable under generic parameter conditions, our formulation

Comment on 'Uniqueness of the Equation for Quantum State Vector Collapse' [arXiv:1303.4284]
, 2014 A diffusive stochastic Schr\"odinger equation (SSE) is shown for the first time, such that contributes to a non-completely positive dynamics. This contradicts to a recent Letter [arXiv:1303.4284] claiming that SSEs, under most general conditions, enforce

Detecting quantum speedup in closed and open systems
New Journal of Physics, 2016 We construct a general measure for detecting the quantum speedup in both closed and open systems. The speed measure is based on the changing rate of the position of quantum states on a manifold with appropriate monotone Riemannian metrics.
