Controlling open quantum systems using fast transitions
(American Physical Society, 2013-02-13)
Unitary control and decoherence appear to be irreconcilable in quantum mechanics. When a quantum system interacts with an environment, control strategies usually fail due to decoherence. In this article we implement a ...
Electrostatic theory for imaging experiments on local charges in quantum Hall systems
(Elsevier Science BvAmsterdamHolanda, 2006)
Dynamics and Thermodynamics of Linear Quantum Open Systems
(Amer Physical Soc, 2013-04-29)
We analyze the evolution of the quantum state of networks of quantum oscillators coupled with arbitrary external environments. We show that the reduced density matrix of the network always obeys a local master equation ...
Effects of chaotic dynamics on quantum friction
(American Physical Society, 2019-04-22)
By means of studying the evolution equation for the Wigner distributions of quantum dissipative systems we derive the quantum corrections to the classical Liouville dynamics, taking into account the standard quantum friction ...
Quantum Theory of Triboelectricity
(2020-10-30)
We propose a microphysical theory of the triboelectric effect by which mechanical rubbing separates charges across the interface between two materials. Surface electrons are treated as an open system coupled to two baths, ...
Signatures of classical structures in the leading eigenstates of quantum dissipative systems
(American Physical Society, 2017-09)
By analyzing a paradigmatic example of the theory of dissipative systems - the classical and quantum dissipative standard map - we are able to explain the main features of the decay to the quantum equilibrium state. The ...
Continuous dynamical decoupling and decoherence-free subspaces for qubits with tunable interaction
(2019-05-01)
Protecting quantum states from the decohering effects of the environment is of great importance for the development of quantum computation devices and quantum simulators. Here, we introduce a continuous dynamical decoupling ...
Conditional states and entropy in qudit-qubit systems
(American Physical Society, 2019-06-25)
We examine, in correlated mixed states of qudit-qubit systems, the set of all conditional qubit states that can be reached after local measurements at the qudit based on rank-1 projectors. While for a similar measurement ...
Quantum Non-Markovian Processes Break Conditional Past-Future Independence
(American Physical Society, 2018-12)
For classical Markovian stochastic systems, past and future events become statistically independent when conditioned to a given state at the present time. Memory non-Markovian effects break this condition, inducing a ...
Quantum work and the thermodynamic cost of quantum measurements
(American Physical Society, 2016-07)
Quantum work is usually determined from two projective measurements of the energy at the beginning and at the end of a thermodynamic process. However, this paradigm cannot be considered thermodynamically consistent as it ...
