Efficient Gaussian Simulations of Fermionic Open Quantum Systems
Yinan Fang, Hyesung Choi, Minchul Lee +1
We review existing classical simulation methods for performing fermionic Gaussian operations and develop new methods to address the gap by adhering to the fundamental theoretical f…
Universal Entanglement Revival of Topological Origin
Dongni Chen, Stefano Chesi, Mahn-Soo Choi
We have analyzed the dynamics of entanglement in dissipative fermionic and bosonic Su-Schrieffer-Heeger (SSH) models and found that, when the decoherence channel preserves the chir…
Global optimization in variational quantum algorithms via dynamic tunneling method
Seung Park, Kyunghyun Baek, Seungjin Lee +1
We present a global optimization routine for the variational quantum algorithms, which utilizes the dynamic tunneling flow. Originally designed to leverage information gathered by…
Self-Purification and Entanglement Revival in Lambda Matter
Dongni Chen, Stefano Chesi, Mahn-Soo Choi
In this study, we explore the dynamics of entanglement in an ensemble of three-level systems with a lambda-type level structure interacting with single-mode bosons. Our investigati…
