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…
Signs of the rates in the Lindblad master equations can always be arbitrarily determined
Le Hu, Andrew N. Jordan
Determining the Markovianity and non-Markovianity of a quantum process is a critical problem in the theory of open quantum systems, as their behaviors differ significantly in terms…
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…
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 collap…
Quantum State Driving along Arbitrary Trajectories
Le Hu, Andrew N. Jordan
Starting with the quantum brachistochrone problem of the infinitesimal form, we solve the minimal time and corresponding time-dependent Hamiltonian to drive a pure quantum state wi…
Achieving Heisenberg Scaling on Measurement of A Three-Qubit System via Quantum Error Correction
Le Hu, Shengshi Pang, Andrew Jordan
In many-body quantum systems, the quantum Fisher information an observer can obtain is susceptible to decoherence. Consequently, quantum enhanced metrology, such as Heisenberg scal…
