Quantum Liang Information Flow vs. Out-of-Time-Order Correlators as Chaos Diagnostics in the Mixed-Field Ising Chain
Bin Yi
We systematically compare Quantum Liang Information Flow (QLIF) a recently proposed causal information measure with the out-of-time-order correlator (OTOC) as diagnostics of quantu…
Directional Dynamics of the Non-Hermitian Skin Effect
Bin Yi
The dynamical consequences of the non-Hermitian skin effect (NHSE) remain largely unexplored despite extensive studies of its static properties. Here we address this gap by applyin…
Quantum Liang Information Flow Probe of Causality across Critical Points
Roopayan Ghosh, Bin Yi, Sougato Bose
Investigating causation in the quantum domain is crucial. Despite numerous studies of correlations in quantum many-body systems, causation, which is very distinct from correlations…
Quantum Liang Information Flow as Causation Quantifier
Bin Yi, Sougato Bose
Liang information flow is a quantity widely used in classical network theory to quantify causation, and has been applied widely, for example, to finance and climate. The most strik…
Massive Spatial Qubits for Testing Macroscopic Nonclassicality and Casimir Induced Entanglement
Bin Yi, Urbasi Sinha, Dipankar Home +2
An open challenge in physics is to expand the frontiers of the validity of quantum mechanics by evidencing nonclassicality of the centre of mass state of a macroscopic object. Yet…
Frozen discord in stochastic dephasing environment
Bin Yi
Preserving quantum coherence is fundamental challenge in the field of quantum computation. Here, I investigate the frozen discord phenomenon and non-Markovianity for qubits experie…
