Symmetry in quantum walks
Hari Krovi
A discrete-time quantum walk on a graph is the repeated application of a unitary evolution operator to a Hilbert space corresponding to the graph. Hitting times for discrete quantu…

Non-Markovian dynamics of a qubit coupled to an Ising spin bath
Hari Krovi, Ognyan Oreshkov, Mikhail Ryazanov +1
We study the analytically solvable Ising model of a single qubit system coupled to a spin bath. The purpose of this study is to analyze and elucidate the performance of Markovian a…

Entanglement-Assisted Quantum Error Correction with Linear Optics
Mark M. Wilde, Hari Krovi, Todd A. Brun
We construct a theory of continuous-variable entanglement-assisted quantum error correction. We present an example of a continuous-variable entanglement-assisted code that corrects…
