Quantum light depolarization: the phase-space perspective
A. B. Klimov, J. L. Romero, L. L. Sanchez-Soto +2
Quantum light depolarization is handled through a master equation obtained by coupling dispersively the field to a randomly distributed atomic reservoir. This master equation is so…
Experimental test of uncertainty relations for quantum mechanics on a circle
J. Rehacek, Z. Bouchal, R. Celechovsky +2
We rederive uncertainty relations for the angular position and momentum of a particle on a circle by employing the exponential of the angle instead of the angle itself, which leads…
Necessary and sufficient detection efficiency for the Mermin inequalities
Adan Cabello, David Rodriguez, Ignacio Villanueva
We prove that the threshold detection efficiency for a loophole-free Bell experiment using an -qubit Greenberger-Horne-Zeilinger state and the correlations appearing in the -…
Statistical Mechanical Models and Topological Color Codes
H. Bombin, M. A. Martin-Delgado
We find that the overlapping of a topological quantum color code state, representing a quantum memory, with a factorized state of qubits can be written as the partition function of…
Sequential Implementation of Global Quantum Operations
L. Lamata, J. Leon, D. Perez-Garcia +2
We study the possibility for a global unitary applied on an arbitrary number of qubits to be decomposed in a sequential unitary procedure, where an ancillary system is allowed to i…
Characterization of quantum angular-momentum fluctuations via principal components
Ángel Rivas, Alfredo Luis
We elaborate an approach to quantum fluctuations of angular momentum based on the diagonalization of the covariance matrix in two versions: real symmetric and complex Hermitian. At…
Quantum Ratchets for Quantum Communication with Optical Superlattices
Oriol Romero-Isart, Juan Jose Garcia-Ripoll
We propose to use a quantum ratchet to transport quantum information in a chain of atoms trapped in an optical superlattice. The quantum ratchet is created by a continuous modulati…
Non-relativistic limit in the 2+1 Dirac Oscillator: A Ramsey Interferometry Effect
A. Bermudez, M. A. Martin-Delgado, A. Luis
We study the non-relativistic limit of a paradigmatic model in Relativistic Quantum Mechanics, the two-dimensional Dirac oscillator. Remarkably, we find a novel kind of Zitterbeweg…
A classification of entanglement in three-qubit systems
Carlos Sabín, Guillermo García-Alcaine
We present a classification of three-qubit states based in their three-qubit and reduced two-qubit entanglements. For pure states these criteria can be easily implemented, and the…
Dynamical instability in kicked Bose-Einstein condensates: Bogoliubov resonances
J. Reslen, C. E. Creffield, T. S. Monteiro
Bose-Einstein condensates subject to short pulses (`kicks') from standing waves of light represent a nonlinear analogue of the well-known chaos paradigm, the quantum kicked rotor.…
Measurement-based quantum computation beyond the one-way model
D. Gross, J. Eisert, N. Schuch +1
We introduce novel schemes for quantum computing based on local measurements on entangled resource states. This work elaborates on the framework established in [Phys. Rev. Lett. 98…
Dirac Cat States in Relativistic Landau Levels
A. Bermudez, M. A. Martin-Delgado, E. Solano
We show that a relativistic version of Schrodinger cat states, here called Dirac cat states, can be built in relativistic Landau levels when an external magnetic field couples to a…
Geometrical approach to mutually unbiased bases
A. B. Klimov, J. L. Romero, G. Bjork +1
We propose a unifying phase-space approach to the construction of mutually unbiased bases for a two-qubit system. It is based on an explicit classification of the geometrical struc…
Chiral entanglement in triangular lattice models
D. I. Tsomokos, J. J. Garcia-Ripoll, N. R. Cooper +1
We consider the low energy spectrum of spin-1/2 two-dimensional triangular lattice models subject to a ferromagnetic Heisenberg interaction and a three spin chiral interaction of v…
Exact Mapping of the 2+1 Dirac Oscillator onto the Jaynes-Cummings Model: Ion-Trap Experimental Proposal
A. Bermudez, M. A. Martin-Delgado, E. Solano
We study the dynamics of the 2+1 Dirac oscillator exactly and find spin oscillations due to a {\it Zitterbewegung} of purely relativistic origin. We find an exact mapping of this q…
Quantum Measurements and Gates by Code Deformation
H. Bombin, M. A. Martin-Delgado
The usual scenario in fault tolerant quantum computation involves certain amount of qubits encoded in each code block, transversal operations between them and destructive measureme…
Optimal Resources for Topological 2D Stabilizer Codes: Comparative Study
H. Bombin, M. A. Martin-Delgado
We study the resources needed to construct topological 2D stabilizer codes as a way to estimate in part their efficiency and this leads us to perform a comparative study of surface…
Unbounded violation of tripartite Bell inequalities
D. Perez-Garcia, M. M Wolf, C. Palazuelos +2
We prove that there are tripartite quantum states (constructed from random unitaries) that can lead to arbitrarily large violations of Bell inequalities for dichotomic observables.…
