Non-Markovian dynamics of open quantum systems via auxiliary particles with exact operator constraint

Physical Review Research
We introduce an auxiliary-particle field theory to treat the non-Markovian dynamics of driven-dissipative quantum systems of the Jaynes-Cummings type.

Collective photon emission in solid state environments: Concatenating non-Markovian and Markovian dynamics

Physical Review Research
Collective light emission and multiqubit dynamics of solid-state quantum emitters are affected both by their coupling to the light field and to lattice vibrations.

Entropic witness for quantum memory in open system dynamics

Physical Review Research
The dynamics of open quantum systems are often modeled by non-Markovian processes that account for memory effects arising from interactions with the environment.

Quantum Error-Corrected Non-Markovian Metrology

PRX Quantum
Quantum metrology aims to maximize measurement precision on quantum systems, with a wide range of applications in quantum sensing. Achieving the Heisenberg limit (HL)—the fundamental precision bound set by quantum mechanics—is often hindered by noise ...

On the non-Markovian quantum stochastic network dynamics

In this paper, we investigate non-Markovian quantum dynamics from the perspective of quantum noises in a network of atoms mediated by a waveguide. In such networks, quantum coherent feedback control becomes achievable when coherent fields (or quantum noises) in the format of photons with continuous modes propagate through the waveguide.
