It is difficult to simulate quantum systems on classical computers, while quantum computers
have been proved to be able to efficiently perform such kinds of simulations. We report an …

Preparing an integrable system in a mixed state described by a thermal density matrix, we
subject it to a sudden quench and explore the subsequent unitary dynamics. To address the …

We introduce the Uhlmann geometric phase as a tool to characterize symmetry-protected
topological phases in one-dimensional fermion systems, such as topological insulators and …

We show that the geometric phase of the ground state in the XY model obeys scaling
behavior in the vicinity of a quantum phase transition. In particular we find that the geometric …

We investigate the interplay between non-Hermiticity and finite temperature in the context of
a mixed-state dynamical quantum phase transition (MSDQPT). We consider ap-wave …

Nonadiabatic holonomic quantum computation provides the means to perform fast and
robust quantum gates by utilizing the resilience of non-Abelian geometric phases to …

Large-scale quantum computers are hard to construct because quantum systems easily lose
their coherence through interaction with the environment. Researchers have tried to avoid …
