Simulating quantum mechanics is known to be a difficult computational problem, especially
when dealing with large systems. However, this difficulty may be overcome by using some …

This paper reviews quantum spin squeezing, which characterizes the sensitivity of a state
with respect to SU (2) rotations, and is significant for both entanglement detection and high …

The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

Quantum simulators are controllable quantum systems that can be used to simulate other
quantum systems. Being able to tackle problems that are intractable on classical computers …

Nonequilibrium quantum many-body systems, which are difficult to study via classical
computation, have attracted wide interest. Quantum simulation can provide insights into …

We consider the phase-transition-like behavior in the Rabi model containing a single two-
level system, or qubit, and a single harmonic oscillator. The system experiences a sudden …

We investigate how symmetries and conserved quantities relate to the occurrence of the
boundary time crystal (BTC) phase in a generalized spin model with Lindblad dissipation …

The single-mode Dicke model is well known to undergo a quantum phase transition from the
so-called normal phase to the superradiant phase (hereinafter called the'superradiant …

We study the all-to-all connected XYZ (anisotropic-Heisenberg) spin model with local and
collective dissipations, comparing the results of mean-field (MF) theory with the solution of …

We theoretically study how to control transport, bound states, and resonant states of a single
photon in a one-dimensional coupled-cavity array. We find that the transport of a single …
