Quantum Optics Seminar by Dara McCutcheon

In this talk I will investigate the distribution of errors on a highly entangled many photon state generated via the continual emission from a quantum dot [1].

Coupling to nuclear spins in the quantum dot environment leads to strongly non-Markovian dynamics, and potentially damaging correlated errors on the photonic state. We will find, however, that the distribution of errors on the resulting photonic state can still be bounded by a Markovian distribution. Crucially, this means that methods for combating errors in quantum computation assuming Markovian models should remain just as effective [2].
