Quantum computers, quantum computing, and quantum thermodynamics
Frontiers in Quantum Science and TechnologyQuantum thermodynamics aims to extend standard thermodynamics and non-equilibrium statistical physics to systems with sizes well below the thermodynamic limit. It is a rapidly evolving research field that promises to change our understanding of the foundations of physics, while enabling the discovery of novel thermodynamic techniques and applications ...

Two-qubit Quantum Logic Gate in Molecular Magnets
, 2006 We proposed a scheme to realize a controlled-NOT quantum logic gate in a dimer of exchange coupled single-molecule magnets, $[\textrm{Mn}_4]_2$. We chosen the ground state and the three low-lying excited states of a dimer in a finite longitudinal ...

Loss-tolerant operations in parity-code linear optics quantum computing [PDF]
, 2007 A heavy focus for optical quantum computing is the introduction of error-correction, and the minimisation of resource requirements. We detail a complete encoding and manipulation scheme designed for linear optics quantum computing, incorporating scalable

Subdivided Phase Oracle for NISQ Search Algorithms
IEEE Transactions on Quantum Engineering, 2020 Because noisy intermediate-scale quantum (NISQ) machines accumulate errors quickly, we need new approaches to designing NISQ-aware algorithms and assessing their performance.

Semiconductor nanowire metamaterial for broadband near-unity absorption
Scientific Reports, 2022 The realization of a semiconductor near-unity absorber in the infrared will provide new capabilities to transform applications in sensing, health, imaging, and quantum information science, especially where portability is required. Typically, commercially

Chinese Physics B, 2023 A theoretical model of computation is proposed based on Lorentz quantum mechanics. Besides the standard qubits, this model has an additional bit, which we call hyperbolic bit (or hybit in short). A set of basic logical gates are constructed and their universality is proved.

Decoding quantum field theory with machine learning
Journal of High Energy Physics, 2023 We demonstrate how one can use machine learning techniques to bypass the technical difficulties of designing an experiment and translating its outcomes into concrete claims about fundamental features of quantum fields.
