Measuring geometric quantum discord using one bit of quantum information
G. Passante, O. Moussa, R. Laflamme
We describe an efficient DQC1-algorithm to quantify the amount of Geometric Quantum Discord present in the output state of a DQC1 computation. DQC1 is a model of computation that u…
Experimental detection of non-classical correlations in mixed state quantum computation
G. Passante, O. Moussa, D. A. Trottier +1
We report on an experiment to detect non-classical correlations in a highly mixed state. The correlations are characterized by the quantum discord and are observed using four qubit…
Geometric measures of entanglement and the Schmidt decomposition
M. E. Carrington, R. Kobes, G. Kunstatter +2
In the standard geometric approach, the entanglement of a pure state is , where is the angle between the entangled state and the closest separable state of products of…
Experimental approximation of the Jones polynomial with DQC1
G. Passante, O. Moussa, C. A. Ryan +1
We present experimental results approximating the Jones polynomial using 4 qubits in a liquid state nuclear magnetic resonance quantum information processor. This is the first expe…
Geometric measures of entanglement and the Schmidt decomposition
D. Ostapchuk, G. Passante, R. Kobes +1
In the standard geometric approach to a measure of entanglement of a pure state, is used, where is the angle between the state to the closest separable state of produ…
The Dynamics of Entanglement in the Adiabatic Search and Deutsch Algorithms
K. Choy, G. Passante, D. Ahrensmeier +4
The goal of this paper is to study the effect of entanglement on the running time of a quantum computation. Adiabatic quantum computation is suited to this kind of study, since it…
