Quantum decoherence of dark pulses in optical microresonators [PDF]
Nature Communications, 2023 Authors report quantum decoherence of dissipative Kerr solitons in normal-dispersion microresonators, also known as dark pulses. They show the quantum decoherence of dark pulses and their potential advantages over bright solitons in an AlGaAs-on ...

Impacts of intrinsic noise and quantum entanglement on the geometric and dynamical properties of the XXZ Heisenberg interacting spin model [PDF]
Scientific ReportsUnderstanding how intrinsic decoherence affects the interplay between geometry, dynamics, and entanglement in quantum systems is a central challenge in quantum information science. In this work, we develop a unified framework that explores this interplay

Physical Review Research, 2021 Decoherence remains one of the most serious challenges to the implementation of quantum technology. It appears as a result of the transformation over time of a quantum superposition state into a classical mixture due to the quantum system interacting ...

Stabilizer codes for open quantum systems
Scientific Reports, 2023 The Lindblad master equation describes the evolution of a large variety of open quantum systems. An important property of some open quantum systems is the existence of decoherence-free subspaces.

New Journal of Physics, 2021 We extend the theory of quantum state engineering (QSE) to the open quantum systems which simultaneously suffer time-dependent decoherence and time-independent decoherence.

Entropy, 2022 Quantum decoherence is crucial to understanding the emergence of the classical world from the underlying quantum reality. Decoherence dynamics are unitary, although they superselect a preferred eigenbasis.

Quantum control in open and periodically driven systems
Advances in Physics: X, 2021 Quantum technology resorts to efficient utilization of quantum resources to realize technique innovation. The systems are controlled such that their states follow the desired manners to realize different quantum protocols. However, the decoherence caused

Experimental quantum decoherence control by dark states of the environment
New Journal of Physics, 2020 Coherent interaction of a quantum system with environment usually induces quantum decoherence. However, remarkably, in certain configurations the coherent system–environment coupling can be simultaneously explored to engineer a specific dark state of the
