Bounds on probability of state transfer with respect to readout time and edge weight
Whitney Gordon, Steve Kirkland, Chi-Kwong Li +2
We analyse the sensitivity of a spin chain modelled by an undirected weighted connected graph exhibiting perfect state transfer to small perturbations in readout time and edge weig…
On the geometric measure of entanglement for pure states
M. E. Carrington, G. Kunstatter, J. Perron +1
The geometric measure of entanglement is the distance or angle between an entangled target state and the nearest unentangled state. Often one considers the geometric measure of ent…
Some geometric interpretations of quantum fidelity
Jin Li, Rajesh Pereira, Sarah Plosker
We consider quantum fidelity between two states and , where we fix and allow to be sent through a quantum channel. We determine the minimal fidelity where one minimi…
Spectra and Variance of Quantum Random Variables
Douglas Farenick, Michael J. Kozdron, Sarah Plosker
We study essentially bounded quantum random variables and show that the Gelfand spectrum of such a quantum random variable coincides with the hypoconvex hull of its essential range…
