Typical Mixing and Rare-State Bottlenecks in Open Quantum Systems
Caisheng Cheng, Ruicheng Bao
Mixing in open quantum systems is often summarized by a single worst-case time, even though that benchmark can be set by exponentially rare initial states. We show that for broad u…
Physically natural metric-measure Lindbladian ensembles and their learning hardness
Caisheng Cheng, Ruicheng Bao
In open quantum systems, a basic question at the interface of quantum information, statistical physics, and many-body dynamics is how well can one infer the structure of noise and…
Quantum spin excitations in a dual-core magnetic molecule
Wenbin Li, Wenwen Shi, Xiaoxiao Xiao +10
Magnetic excitations are important quantum phenomena in magnetic systems and have been widely studied in individual magnetic atoms and molecules as well as their assembled structur…
Unconditionally decoherence-free quantum error mitigation by density matrix vectorization
Zhong-Xia Shang, Zi-Han Chen, Cai-Sheng Cheng
Fighting against noise is crucial for NISQ devices to demonstrate practical quantum applications. In this work, we give a new paradigm of quantum error mitigation based on the vect…
Surface-state Coulomb repulsion accelerates a metal-insulator transition in topological semimetal nanofilms
S. Ito, M. Arita, J. Haruyama +11
The emergence of quantization at the nanoscale, the quantum size effect (QSE), allows flexible control of matter and is a rich source of advanced functionalities. A QSE-induced tra…
Proving Nontrivial Topology of Pure Bismuth by Quantum Confinement
S. Ito, B. Feng, M. Arita +13
The topology of pure Bi is controversial because of its very small (10 meV) band gap. Here we perform high-resolution angle-resolved photoelectron spectroscopy measurements s…
