Thermal baths as quantum resources: More friends than foes?
(IOP Publishing, 2015-11-06)
In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their applications to quantum technologies. One ...
Remote state preparation of a photonic quantum state via quantum teleportation
(Springer Verlag Berlín, 2014-06)
We demonstrate an experimental realization of remote state preparation via the quantum teleportation algorithm, using an entangled photon pair in the polarization degree of freedom as the quantum resource. The input state ...
Why entanglement of formation is not generally monogamous
(2013-03-13)
Unlike correlation of classical systems, entanglement of quantum systems cannot be distributed at will: if one system A is maximally entangled with another system B, it cannot be entangled at all with a third system C. ...
Entropy effect in quantum computing and information: an open-source environment simulation
(2014)
The technologies are rapidly developing, but some of them present in the computers, as for instance their processing capacity, are reaching their physical limits. It is up to quantum computation offer solutions to these ...
Optimal control of a charge qubit in a double quantum dot with a Coulomb impurity
(Elsevier Science, 2017-02)
We study the efficiency of modulated external electric pulses to produce efficient and fast charge localization transitions in a two-electron double quantum dot. We use a configuration interaction method to calculate the ...
Quantum correlations from classically correlated states
(Elsevier Science, 2014-07)
Consider a bipartite quantum system with at least one of its two components being itself a composite system. By tracing over part of one (or both) of these two subsystems it is possible to obtain a reduced (separable) state ...
Sending classical information through relativistic quantum channels
(2013-04-29)
We investigate how special relativity influences the transmission of classical information through quantum channels by evaluating the Holevo bound when the sender and the receiver are in (relativistic) relative motion. By ...
The classical limit of non-integrable quantum systems, a route to quantum chaos
(Elsevier, 2006-04)
The classical limit of non-integrable quantum systems is studied. We define non-integrable quantum systems as those, which have, as their classical limit, a non-integrable classical system. This quantum systems will be the ...
Quantum correlations and coherence between two particles interacting with a thermal bath
(IOP Publishing, 2017-05)
Quantum correlations and coherence generated between two free spinless particles in the lattice, interacting with a common quantum phonon bath, are studied. The reduced density matrix is solved using the Markov approach. ...
Computational advantage from the quantum superposition of multiple temporal orders of photonic gates
