The geometric phase has the intrinsic property of being resistant to some types of local
noises as it only depends on global properties of the evolution path. Meanwhile, the non …

Quantum information processing enhances human's power to simulate nature in quantum
level and solve complex problem efficiently. During the process, a series of operators is …

A conceptual framework extending (time-independent) PT-symmetric quantum mechanics
into the time-dependent domain is presented. It is built upon a nontrivial time-dependent …

Non-Hermitian (NH) quantum systems attract research interest increasingly in recent years,
among which the PT-symmetric, P-pseudo-Hermitian and their anti-symmetric counterpart …

Besides Hermitian systems, quantum simulation has become a strong tool to investigate non-
Hermitian systems, such as PT-symmetric, anti-PT-symmetric, and pseudo-Hermitian …

Non-Hermitian (NH) quantum theory has been attracting increased research interest due to
its featured properties, novel phenomena, and links to open and dissipative systems. Typical …

Different from the Hermitian case, non-Hermitian (NH) systems have novel properties and
strongly relate to open and dissipative quantum systems. In this work, we investigate how to …

Quantum physics can be extended into the complex domain by considering non-Hermitian
Hamiltonians that are $\mathcal {PT} $-symmetric. These exhibit exceptional points (EPs) …

In this work we present the general unified description for the unitary time evolution
generated by time-dependent non-Hermitian Hamiltonians embedding the bosonic …
