Analog control of open quantum systems under arbitrary decoherence
Jens Clausen, Guy Bensky, Gershon Kurizki
We derive and investigate a general non-Markovian equation for the time-dependence of a Hamiltonian that maximizes the fidelity of a desired quantum gate on any finite-dimensional…
Non-Markovian control of qubit thermodynamics by frequent quantum measurements
Guy Bensky, D. D. Bhaktavatsala Rao, Goren Gordon +3
We explore the effects of frequent, impulsive quantum nondemolition measurements of the energy of two-level systems (TLS), alias qubits, in contact with a thermal bath. The resulti…
Universal protection of unitary evolution from slow noise: dynamical control pushed to the extreme
G. Bensky, E. Brion, F. Carlier +2
We propose a technique that allows to simultaneously perform universal control of the evolution operator and compensate for the first order contribution of an arbitrary Hermitian c…
Path-Phase Information Complementarity for Interfering Particles through State-Discrimination
Noam Erez, Daniel Jacobs, Gershon Kurizki
We analyze the trade-off between the amounts of information obtainable on complementary properties of a qubit state by simultaneous measurements. We consider a "state discriminatio…
Operational path-phase complementarity in single-photon interferometry
Noam Erez, Daniel Jacobs, Gershon Kurizki
We examine two setups that reveal different operational implications of path-phase complementarity for single photons in a Mach-Zehnder interferometer (MZI). In both setups, the wh…
Master Equation and Control of an Open Quantum System with Leakage
Lian-Ao Wu, Gershon Kurizki, Paul Brumer
Given a multilevel system coupled to a bath, we use a Feshbach P,Q partitioning technique to derive an exact trace-nonpreserving master equation for a subspace of…
