Phase-space characterization of complexity in quantum many-body dynamics
Vinitha Balachandran, Giuliano Benenti, Giulio Casati +1
We propose a phase-space Wigner harmonics entropy measure for many-body quantum dynamical complexity. This measure, which reduces to the well known measure of complexity in classic…
Protecting unknown two-qubit entangled states by nesting Uhrig's dynamical decoupling sequences
Musawwadah Mukhtar, Wee Tee Soh, Thuan Beng Saw +1
Future quantum technologies rely heavily on good protection of quantum entanglement against environment-induced decoherence. A recent study showed that an extension of Uhrig's dyna…
Geometric Phase in PT-Symmetric Quantum Mechanics
Jiangbin Gong, Qing-hai Wang
Unitary evolution in PT-symmetric quantum mechanics with a time-dependent metric is found to yield a new class of adiabatic processes. As an explicit example, a Berry-like phase as…
Driven Dirac-like Equation via Mirror Oscillation: Controlled Cold-Atom Zitterbewegung
Qi Zhang, Jiangbin Gong, C. H. Oh
By considering mirror oscillation in a "tripod-scheme" laser-atom system, we advocate explorative studies of driven Dirac-like equations. Both analytical and numerical studies show…
Indistinguishability and Interference in the Coherent Control of Atomic and Molecular Processes
Jiangbin Gong, Paul Brumer
The subtle and fundamental issue of indistinguishability and interference between independent pathways to the same target state is examined in the context of coherent control of at…
