Stochastic optimal control formalism for an open quantum system
Chungwei Lin, Dries Sels, Yanting Ma +1
A stochastic procedure is developed which allows one to express Pontryagin's maximum principle for dissipative quantum system solely in terms of stochastic wave functions. Time-opt…
Dynamical obstruction to localization in a disordered spin chain
Dries Sels, Anatoli Polkovnikov
We analyze a one-dimensional XXZ spin chain in a disordered magnetic field. As the main probes of the system's behavior we use the sensitivity of eigenstates to adiabatic transform…
Counterdiabatic control of transport in a synthetic tight-binding lattice
Eric J. Meier, Kinfung Ngan, Dries Sels +1
Quantum state transformations that are robust to experimental imperfections are important for applications in quantum information science and quantum sensing. Counterdiabatic (CD)…
Non-Gaussian correlations imprinted by local dephasing in fermionic wires
Pavel E. Dolgirev, Jamir Marino, Dries Sels +1
We study the behavior of an extended fermionic wire coupled to a local stochastic field. Since the quantum jump operator is Hermitian and quadratic in fermionic operators, it rende…
Adiabatic eigenstate deformations as a sensitive probe for quantum chaos
Mohit Pandey, Pieter W. Claeys, David K. Campbell +2
In the past decades, it was recognized that quantum chaos, which is essential for the emergence of statistical mechanics and thermodynamics, manifests itself in the effective descr…
Time-optimal control of a dissipative qubit
Chungwei Lin, Dries Sels, Yebin Wang
A formalism based on Pontryagin's maximum principle is applied to determine the time-optimal protocol that drives a general initial state to a target state by a Hamiltonian with li…
