Quantum coherence and interference patterns — •Florian Mintert — Imperial College London

Quantum coherence is the basis for many quantum technological applications. Quantum sensors often rely on the coherent superposition of only two system eigenstates, whereas a quantum computer would exploit the superposition of many such basis states. Our ability to build quantum devices can thus be characterised in terms of the number of of eigenstates that we manage to coherently superpose. I will discuss how this number can be read off an interference pattern and report on our progress towards tests that can assess this number in the presence of experimental imperfections.
