The traditional view from particle physics is that quantum gravity effects should only become
detectable at extremely high energies and small length scales. Due to the significant …

Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

Mechanical systems prepared in quantum non-Gaussian states constitute a new advanced
class of phenomena breaking the laws of classical physics. Specifically, such mechanical …

We explore the photon-controlled phonon statistics in a hybrid spin-optomechanical system.
Here the proposed phonon blockade is based on the nonlinearity of system induced by the …

We propose a feasible experimental scheme to improve the few-photon optomechanical
effects, including photon blockade and mechanical-Schrödinger-cat-state generation, as …

We present a method to implement two-phonon interactions between mechanical resonators
and spin qubits in hybrid setups, and show that these systems can be applied for the …

A scheme is proposed to cool a rotating mirror close to its ground state in a double-Laguerre-
Gaussian-cavity optomechanical system, where an auxiliary cavity and a two-level atomic …

Laser cooling is a fundamental technique used in primary atomic frequency standards,
quantum computers, quantum condensed matter physics and tests of fundamental physics …

The quantum simulation of dynamical gauge field theories offers the opportunity to study
complex high-energy physics with controllable low-energy devices. For quantum …

Adding excitations on a coherent state provides an effective way to observe the nonclassical
properties of radiation fields. Here, we describe and analyze how to apply this concept to the …
