Abstract

This thesis focuses on detecting correlated errors in quantum systems using loop state-preparation-and-measurement (SPAM) tomography. I discuss a two-qubit quantum system through the lens of quantum cryptography: an eavesdropper has introduced “correlated errors” into a quantum machine designed to distribute a secure encryption key between two parties. The errors have corrupted the machine and made it appear secure, when in fact it is not. I experimentally demonstrate that loop SPAM tomography can identify these errors using only measured data and minimal assumptions.
