Describing the Wave Function Collapse Process with a State-dependent Hamiltonian
Le Hu, Andrew N. Jordan
It is well-known that quantum mechanics admits two distinct evolutions: the unitary evolution, which is deterministic and well described by the Schrödinger equation, and the colla…
Unified trajectory criterion for quantum and classical non-Markovianity
Le Hu, Archana Kamal
We propose a simple criterion for non-Markovianity: a quantum master equation is non-Markovian if and only if its \textit{trajectory set} contains a \textit{self-intersecting traje…
Entanglement dynamics in collision models and entanglement quilts
Le Hu, Andrew N. Jordan
We study the entanglement dynamics of a family of quantum collision models by analytically solving the pairwise concurrence for all qubit pairs. We introduce a diagrammatic method…
Probabilistic Unitary Formulation of Open Quantum System Dynamics
Le Hu, Andrew N. Jordan
We show that all non-relativistic quantum processes, whether open or closed, are either unitary or probabilistic unitary, i.e., probabilistic combination of unitary evolutions. Thi…
