Coherent Communication with Linear Optics
Mark M. Wilde, Todd A. Brun, Jonathan P. Dowling +1
We show how to implement several continuous-variable coherent protocols with linear optics. Noise can accumulate when implementing each coherent protocol with realistic optical dev…
General entanglement-assisted quantum error-correcting codes
Min-Hsiu Hsieh, Igor Devetak, Todd Brun
Entanglement-assisted quantum error-correcting codes (EAQECCs) make use of pre-existing entanglement between the sender and receiver to boost the rate of transmission. It is possib…
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…
Continuous quantum error correction for non-Markovian decoherence
Ognyan Oreshkov, Todd A. Brun
We study the effect of continuous quantum error correction in the case where each qubit in a codeword is subject to a general Hamiltonian interaction with an independent bath. We f…
Quantum walks on quotient graphs
Hari Krovi, Todd A. Brun
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. If this unitary evolution operato…
A Matrix Factorization of Extended Hamiltonian Leads to -Particle Pauli Equation
Irving S. Reed, Todd A. Brun
In this paper the Levy-Leblond procedure for linearizing the Schrödinger equation to obtain the Pauli equation for one particle is generalized to obtain an -particle equation wi…
