Interplay between external driving, dissipation and collective effects in the Markovian and non-Markovian regimes
Roie Dann
Understanding how external driving and dissipation jointly influence the dynamics of open quantum systems is essential for advancing the study of non-equilibrium quantum phenomena…
Inertial geometric quantum logic gates
Daniel Turyansky, Oded Ovdat, Roie Dann +4
We present rapid and robust protocols for STIRAP and quantum logic gates. Our gates are based on geometric phases acquired by instantaneous eigenstates of a slowly accelerating ine…
Unification of the first law of quantum thermodynamics
Roie Dann, Ronnie Kosloff
Underlying the classical thermodynamic principles are analogous microscopic laws, arising from the fundamental axioms of quantum mechanics. These define quantum thermodynamic varia…
Controlling the uncontrollable: Quantum control of open system dynamics
Shimshon Kallush, Roie Dann, Ronnie Kosloff
Control of open quantum systems is an essential ingredient to the realization of contemporary quantum science and technology. We demonstrate such control by employing a thermodynam…
Controlling the uncontrollable: Quantum control of open system dynamics
Shimshon Kallush, Roie Dann, Ronnie Kosloff
Quantum control of an open system is demonstrated employing a thermodynamically consistent master equation. In this framework, the open system dynamics depend on the control protoc…
Non-Markovian dynamics under time-translation symmetry
Roie Dann, Nina Megier, Ronnie Kosloff
A dynamical symmetry is employed to determine the structure of the quantum non-Markovian time-local master equation. Such a structure is composed from two components: scalar kineti…
Open system dynamics from thermodynamic compatibility
Roie Dann, Ronnie Kosloff
Thermodynamics entails a set of mathematical conditions on quantum Markovian dynamics. In particular, strict energy conservation between the system and environment implies that the…
Quantum thermo-dynamical construction for driven open quantum systems
Roie Dann, Ronnie Kosloff
Quantum dynamics of driven open systems should be compatible with both quantum mechanic and thermodynamic principles. By formulating the thermodynamic principles in terms of a set…
Quantum finite-time thermodynamics: insight from a single qubit engine
Roie Dann, Ronnie Kosloff, Peter Salamon
Incorporating time into thermodynamics allows addressing the tradeoff between efficiency and power. A qubit engine serves as a toy model to study this tradeoff from first principle…
Variational solutions for Resonances by a Finite-Difference Grid Method
Roie Dann, Guy Elbaz, Jonathan Berkheim +4
We demonstrate that the finite difference grid method (FDM) can be simply modified to satisfy the variational principle and enable calculations of both real and complex poles of th…
Fast Route to Thermalization
Roie Dann, Ander Tobalina, Ronnie Kosloff
We present a control scheme for quantum systems coupled to a thermal bath. We demonstrate state-to-state control between two Gibbs states. This scheme can be used to accelerate the…
Quantum Signatures in the Quantum Carnot Cycle
Roie Dann, Ronnie Kosloff
The Carnot cycle combines reversible isothermal and adiabatic strokes to obtain optimal efficiency, at the expense of a vanishing power output. Quantum Carnot-analog cycles are con…
Experimental verification of the inertial theorem control protocols
Chang-Kang Hu, Roie Dann, Jin-Ming Cui +5
An experiment based on a trapped Ytterbium ion validates the inertial theorem for the SU(2) algebra. The qubit is encoded within the hyperfine states of the atom and controlled by…
Shortcut to Equilibration of an Open Quantum System
Roie Dann, Ander Tobalina, Ronnie Kosloff
We present a procedure to accelerate the relaxation of an open quantum system towards its equilibrium state. The control protocol, termed Shortcut to Equilibration, is obtained by…
