A proposed test of quantum dissipation theory using Kapitza–Dirac electron diffraction
New Journal of Physics, 2022 Decoherence can be provided by a dissipative environment as described by the Caldeira–Leggett equation. This equation is foundational to the theory of quantum dissipation.

Advanced Science, EarlyView.A nanoparticle‐cluster‐on‐mirror (NPcoM) serves as a functionally deterministic sub‐nanocavity that emulates picocavities, enabling extreme light–matter interactions and polaritonic phenomena. ABSTRACT Pushing nanoscale optical confinement to its ultimate limits defines the regime of nano‐cavity quantum electrodynamics (nano‐cQED), where light‐matter ...

Advanced Electronic Materials, EarlyView.Ising machines are emerging as specialized hardware solvers for computationally hard optimization problems. This review examines five major platforms—digital CMOS, analog CMOS, emerging devices, coherent optics, and quantum systems—highlighting physics‐rooted advantages and shared bottlenecks in scalability and connectivity.

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range
Advanced Electronic Materials, EarlyView.A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

Decoherence, control, and encoding of coupled solid-state quantum bits [PDF]
, 2005 In this thesis the decoherence properties, gate performance, control of solid-state quantum bits (qubits), and novel design proposals for solid-state qubits analogous to quantum optics are investigated.

Classical signature of quantum annealing
Frontiers in Physics, 2014 A pair of recent articles concluded that the D-Wave One machine actuallyoperates in the quantum regime, rather than performing some classical evolution.

Stability of the Discrete Time-Crystalline Order in Spin-Optomechanical and Open Cavity QED Systems
Photonics, 2022 Discrete time crystals (DTC) have been demonstrated experimentally in several different quantum systems in the past few years. Spin couplings and cavity losses have been shown to play crucial roles for realizing DTC order in open many-body systems out of

Advanced Intelligent Discovery, EarlyView.In this study we employed support vector regressor and quantum support vector regressor to predict the hydrogen storage capacity of metal–organic frameworks using structural and physicochemical descriptors. This study presents a comparative analysis of classical support vector regression (SVR) and quantum support vector regression (QSVR) in predicting ...

Transverse decoherence and coherent spectra in long bunches with space charge
Physical Review Special Topics. Accelerators and Beams, 2012 The transverse bunch spectrum and the transverse decoherence/recoherence following an initial bunch offset are important phenomena in synchrotrons and storage rings, and are widely used for beam and lattice measurements.

Implementation of Classical Communication in a Quantum World
Information, 2012 Observations of quantum systems carried out by finite observers who subsequently communicate their results using classical data structures can be described as “local operations, classical communication” (LOCC) observations.
