Cold atoms in non-Abelian gauge potentials: From the Hofstadter "moth" to lattice gauge theory
K. Osterloh, M. Baig, L. Santos +2
We demonstrate how to create artificial external non-Abelian gauge potentials acting on cold atoms in optical lattices. The method employs internal states of atoms and laser as…
Secrecy content of two-qubit states
A. Acín, J. Bae, E. Bagan +3
We analyze the set of two-qubit states from which a secret key can be extracted by single-copy measurements plus classical processing of the outcomes. We introduce a key distillati…
Multiple copy 2-state discrimination with individual measurements
A Acin, E. Bagan, M. Baig +2
We address the problem of non-orthogonal two-state discrimination when multiple copies of the unknown state are available. We give the optimal strategy when only fixed individual m…
Quantum reverse-engineering and reference frame alignment without non-local correlations
E. Bagan, M. Baig, R. Munoz-Tapia
Estimation of unknown qubit elementary gates and alignment of reference frames are formally the same problem. Using quantum states made out of qubits, we show that the theoreti…
Fixed boundary conditions analysis of the 3d Gonihedric Ising model with
M. Baig, J. Clua, D. A. Johnston +1
The Gonihedric Ising model is a particular case of the class of models defined by Savvidy and Wegner intended as discrete versions of string theories on cubic lattices. In this pap…
Optimal reconstruction of a pure qubit state with local measurements
E. Bagan, M. Baig, A. Monras +1
We analyse the reconstruction of an unknown pure qubit state. We derive the optimal guess that can be inferred from any set of measurements on N identical copies of the system with…
