Long-range quantum discord in critical spin systems
J. Maziero, L. C. Céleri, R. M. Serra +1
We show that quantum correlations as quantified by quantum discord can characterize quantum phase transitions by exhibiting nontrivial long-range decay as a function of distance in…
Fractional topological phase for entangled qudits
L. E. Oxman, A. Z. Khoury
We investigate the topological structure of entangled qudits under unitary local operations. Different sectors are identified in the evolution, and their geometrical and topologica…
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…
Closed timelike curves in measurement-based quantum computation
Raphael Dias da Silva, Ernesto F. Galvao, Elham Kashefi
Many results have been recently obtained regarding the power of hypothetical closed time-like curves (CTCs) in quantum computation. Here we show that the one-way model of measureme…
Quantum and classical thermal correlations in the XY spin-1/2 chain
J. Maziero, H. C. Guzman, L. C. Celeri +2
We investigate pairwise quantum correlation as measured by the quantum discord as well as its classical counterpart in the thermodynamic limit of anisotropic XY spin-1/2 chains in…
