Fluctuation Theorems for a Quantum Channel
Hyuk-Joon Kwon,Myungshik Kim +1 more
TL;DR: In this paper, the authors established the general framework of quantum fluctuation theorems by finding the symmetry between the forward and backward transitions of any given quantum channel, and the notion of entropy production in thermodynamics was extended to the quantum regime.
Journal ArticleDOI
Photon number distributions for squeezed number states and squeezed thermal states
TL;DR: In this paper, the photon statistics of squeezed number states and thermal states were derived using the Wigner functions for the squeezed fields and the photon number distribution was interpreted in terms of phase-space interference.
Journal ArticleDOI
Quantum limits to gravity estimation with optomechanics
TL;DR: In this article, a table-top quantum estimation protocol is presented to measure the gravitational acceleration by using an optomechanical cavity, exploiting the nonlinear quantum light-matter interaction between an optical field and a massive mirror acting as a mechanical oscillator.
Journal ArticleDOI
Simple mitigation of global depolarizing errors in quantum simulations.
Joseph Vovrosh,Kiran E. Khosla,Sean Greenaway,Chris N. Self,Myungshik Kim,Johannes Knolle,Johannes Knolle +6 more
TL;DR: In this article, the authors proposed an error mitigation technique based on the assumption that noise in a deep quantum circuit is well described by global depolarizing error channels, and they used an error model ansatz to infer error-free results from noisy data.
Journal ArticleDOI
Operationally invariant measure of the distance between quantum states by complementary measurements.
TL;DR: It is shown that the measure is operationally invariant and it is equivalent to the Hilbert-Schmidt distance, which provides a remarkable interpretation of the information distance between quantum states.
