In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

A large number of experimental discoveries especially in the heavy quarkonium sector that
did not meet the expectations of the until then very successful quark model led to a …

We propose how to create and manipulate one-way nonclassical light via photon blockade
in rotating nonlinear devices. We refer to this effect as nonreciprocal photon blockade (PB) …

Hybrid quantum circuits combine two or more physical systems, with the goal of harnessing
the advantages and strengths of the different systems in order to better explore new …

We investigate the performance of entangled coherent states for quantum-enhanced phase
estimation. An exact analytical expression of quantum Fisher information is derived to show …

The implementation of a single magnon level quantum manipulation is one of the
fundamental targets in quantum magnetism with a significant practical relevance for …

We propose an experimentally realizable nonreciprocal magnonic device at the single-
magnon level by exploiting magnon blockade in a magnon-based hybrid system. The …

The dynamics of two variants of quantum Fisher information under decoherence is
investigated from a geometrical point of view. We first derive the explicit formulas of these …

We study the dynamics of a driven optomechanical cavity coupled to a charged
nanomechanical resonator via Coulomb interaction, in which the tunable double …

Some optomechanical systems can be transparent to a probe field when a strong driving
field is applied. These systems can provide an optomechanical analog of …
