Jarzynski-like Equality of Nonequilibrium Information Production Based on Quantum Cross Entropy
Akira Sone, Naoki Yamamoto, Tharon Holdsworth +1
The two-time measurement scheme is well studied in the context of quantum fluctuation theorem. However, it becomes infeasible when the random variable determined by a single measur…
Inference-Based Quantum Sensing
C. Huerta Alderete, Max Hunter Gordon, Frederic Sauvage +4
In a standard Quantum Sensing (QS) task one aims at estimating an unknown parameter , encoded into an -qubit probe state, via measurements of the system. The success of this…
Quantum Computational Phase Transition in Combinatorial Problems
Bingzhi Zhang, Akira Sone, Quntao Zhuang
Quantum Approximate Optimization algorithm (QAOA) aims to search for approximate solutions to discrete optimization problems with near-term quantum computers. As there are no algor…
Quantum and classical ergotropy from relative entropies
Akira Sone, Sebastian Deffner
The quantum ergotropy quantifies the maximal amount of work that can be extracted from a quantum state without changing its entropy. Given that the ergotropy can be expressed as th…
Demonstration of quantum advantage by a joint detection receiver for optical communications using quantum belief propagation on a trapped-ion device
Conor Delaney, Kaushik P. Seshadreesan, Ian MacCormack +3
Demonstrations of quantum advantage have largely focused on computational speedups and on quantum simulation of many-body physics, limited by fidelity and capability of current dev…
Sub-Quantum Fisher Information
M. Cerezo, Akira Sone, Jacob L. Beckey +1
The Quantum Fisher Information (QFI) plays a crucial role in quantum information theory and in many practical applications such as quantum metrology. However, computing the QFI is…
Variational Quantum Algorithm for Estimating the Quantum Fisher Information
Jacob L. Beckey, M. Cerezo, Akira Sone +1
The Quantum Fisher information (QFI) quantifies the ultimate precision of estimating a parameter from a quantum state, and can be regarded as a reliability measure of a quantum sys…
Generalized Measure of Quantum Fisher Information
Akira Sone, M. Cerezo, Jacob L. Beckey +1
In this work, we present a lower bound on the quantum Fisher information (QFI) which is efficiently computable on near-term quantum devices. This bound itself is of interest, as we…
