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…

Decoherence of a Single Qubit from Quantum Anomaly
W. F. Chen, R. Kobes, G. Kunstatter
We show via an explicit example that quantum anomalies can lead to decoherence of a single quantum qubit through phase relaxation. The anomaly causes the Hamiltonian to develop a n…
