In open quantum systems, the precision of metrology inevitably suffers from the noise. In
Markovian open quantum dynamics, the precision can not be improved by using entangled …

We consider two separate atoms interacting with a single-mode optical or microwave
resonator. When the frequency of the resonator field is twice the atomic transition frequency …

We study the non-Markovian dynamics of a two-level giant atom interacting with a one-
dimensional semi-infinite waveguide through multiple coupling points, where a perfect …

In a fully-controllable experiment platform for studying non-Markovian open quantum
dynamics, we show that the non-Markovianity could be investigated from the global and …

Hyperentanglement, defined as the simultaneous entanglement in several independent
degrees of freedom (DOFs) of a quantum system, is a fascinating resource in quantum …

Spontaneous parametric down-conversion is a well-known process in quantum nonlinear
optics in which a photon incident on a nonlinear crystal spontaneously splits into two …

The ability to entangle quantum systems is crucial for many applications in quantum
technology, including quantum communication and quantum computing. Here, we propose …

We demonstrate parametric all-optical modulation in a periodically poled lithium niobate
microring resonator on a chip. It uses quantum Zeno blockade between two distinct waves, a …

We investigate theoretically the quantum Rabi model in the large-detuning regime. When
the frequency of the cavity field is near one-third of the atomic transition frequency, we show …

In this work, we investigate the non-Markovian (NM) dynamical evolution of a three-level
atom coupled to a semi-infinite one-dimensional photonic waveguide and driven by a …
