Spatial Qubit Entanglement Witness for Quantum Natured Gravity
Bin Yi, Urbasi Sinha, Dipankar Home +2
Evidencing the quantum nature of gravity through the entanglement of two masses has recently been proposed. Proposals using qubits to witness this entanglement can afford to bring…
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…
