Parent Hamiltonian and intrinsic phase transition in non-Hermitian photonic systems
Yuntao Xiao, Yuchen Guo, Xiaojian Huang +6
Non-Hermitian systems host phenomena absent in Hermitian physics, but realizing Hamiltonians with intrinsic non-Hermitian properties remains challenging. The theoretical method of…
Quantum criticality in open quantum systems from the purification perspective
Yuchen Guo, Shuo Yang
Open quantum systems host mixed-state phases that go beyond the symmetry-protected topological and spontaneous symmetry-breaking paradigms established for closed, pure-state system…
A New Framework for Quantum Phases in Open Systems: Steady State of Imaginary-Time Lindbladian Evolution
Yuchen Guo, Ke Ding, Shuo Yang
This study delves into the concept of quantum phases in open quantum systems, examining the shortcomings of existing approaches that focus on steady states of Lindbladians and high…
Efficient Quantum Circuit Compilation for Near-Term Quantum Advantage
Yuchen Guo, Shuo Yang
Quantum noise in real-world devices poses a significant challenge in achieving practical quantum advantage, since accurately compiled and executed circuits are typically deep and h…
