Chris Sutherland: Mode Mismatch in a Mutually Unbiased Basis Measurement Scheme

Chris Sutherland, Institute for Quantum Computing (IQC)

Abstract

Quantum cryptography protocols for qudit systems have been well established, but the ways to implement a mutually unbiased basis measurement have not been. In this talk I will describe the proposed measurement scheme, and also describe how to account for the common experimental challenge of mode-mismatch between two distinct laser pulses. I will also show how this effects the result of the measurement, and how much mode mismatch can be tolerated.
