Emergence of Thermodynamics from Equilibration in Isolated Quantum Systems
Adalberto D. Varizi, Daniel Jonathan, Thiago R. de Oliveira
Understanding how macroscopic thermodynamic behavior emerges from microscopic quantum dynamics remains an open problem. While equilibration of quantum observables is well establish…
Optical computing of quantum revivals
Mayanne R. Maia, Daniel Jonathan, Thiago R. Oliveira +2
Interference is the mechanism through which waves can be structured into the most fascinating patterns. While for sensing, imaging, trapping, or in fundamental investigations, stru…
Nonadiabatic coupled-qubit Otto cycle with bidirectional operation and efficiency gains
Cleverson Cherubim, Thiago R. de Oliveira, Daniel Jonathan
We study a quantum Otto cycle that uses a 2-qubit working substance whose Hamiltonian does not commute with itself at different times during unitary strokes. We investigate how the…
Measurement-based quantum heat engine in a multilevel system
Maron F. Anka, Thiago R. de Oliveira, Daniel Jonathan
We compare quantum Otto engines based on two different cycle models: a two-bath model, with a standard heat source and sink, and a measurement-based protocol, where the role of hea…
Efficiency gain and bidirectional operation of quantum engines with decoupled internal levels
Thiago R. de Oliveira, Daniel Jonathan
We present a mechanism for efficiency increase in quantum heat engines containing internal energy levels that do not couple to the external work sink. The gain is achieved by using…
Equilibration time scales in closed many-body quantum systems
Thiago R. de Oliveira, Christos Charalambous, Daniel Jonathan +2
We show that the physical mechanism for the equilibration of closed quantum systems is dephasing, and identify the energy scales that determine the equilibration timescale of a giv…
Comment on the paper "Random Quantum Circuits are Approximate 2-designs"
Igor Tuche Diniz, Daniel Jonathan
In [A.W. Harrow and R.A. Low, Commun. Math. Phys. 291, 257-302 (2009)], it was shown that a quantum circuit composed of random 2-qubit gates converges to an approximate quantum 2-d…
Quantum Information Processing in Strongly Detuned Optical Cavities
E. Jane, M. B. Plenio, D. Jonathan
We demonstrate that quantum information processing can be implemented with ions trapped in a far detuned optical cavity. For sufficiently large detuning the system becomes insensit…
A family of exact eigenstates for a single trapped ion interacting with a laser field
H. Moya-Cessa, D. Jonathan, P. L. Knight
We show that, under certain combinations of the parameters governing the interaction of a harmonically trapped ion with a laser beam, it is possible to find one or more exact eigen…
Light-shift-induced quantum gates for ions in thermal motion
Daniel Jonathan, Martin B. Plenio
An effective interaction between trapped ions in thermal motion can be generated by illuminating them simultaneously with a single laser resonant with the ionic carrier frequency.…
Fast quantum gates for cold trapped ions
D. Jonathan, M. B. Plenio, P. L. Knight
We present an alternative scheme for the generation of a 2-qubit quantum gate interaction between laser-cooled trapped ions. The scheme is based on the AC Stark shift (lightshift)…
Optical Bell Measurement by Fock Filtering
MGA Paris, M Plenio, D Jonathan +2
We describe a nonlinear interferometric setup to perform a complete optical Bell measurement, i.e. to unambigously discriminate the four polarization entangled EPR-Bell photon pair…
Approximate transformations and robust manipulation of bipartite pure state entanglement
Guifre Vidal, Daniel Jonathan, M. A. Nielsen
We analyze approximate transformations of pure entangled quantum states by local operations and classical communication, finding explicit conversion strategies which optimize the f…
Entanglement-assisted local manipulation of pure quantum states
Daniel Jonathan, Martin B. Plenio
We demonstrate that local transformations on a composite quantum system can be enhanced in the presence of certain entangled states. These extra states act much like catalysts in a…
Dressed-State Approach to Population Trapping in the Jaynes-Cummings Model
D. Jonathan, A. Vidiella-Barranco, K. Furuya
The phenomenon of atomic population trapping in the Jaynes-Cummings Model is analysed from a dressed-state point of view. A general condition for the occurrence of partial or total…
Minimal conditions for local pure-state entanglement manipulation
Daniel Jonathan, Martin B. Plenio
We find a minimal set of necessary and sufficient conditions for the existence of a local procedure that converts a finite pure state into one of a set of possible final states. Th…
Quantum telecloning and multiparticle entanglement
M. Murao, D. Jonathan, M. B. Plenio +1
A quantum telecloning process combining quantum teleportation and optimal quantum cloning from one input to M outputs is presented. The scheme relies on the establishment of partic…
