We investigate the effect of nuclear spins on the phase shift and polarisation rotation of photons scattered off a quantum dot-cavity system. We show that as the phase shift depends strongly on the resonance energy of an electronic transition in the quantum dot, it can provide a sensitive probe of the quantum state of nuclear spins that broaden this transition energy. By including the electron-nuclear spin coupling at a Hamiltonian level within an extended input-output formalism, we show how a…

Spin coherence can be improved by applying large magnetic fields and reducing strain inhomogeneity by recovering the intrinsic coherence time set by the interaction with the inhomogeneously strained nuclear bath.

Role of the electron spin in determining the coherence of the nuclear spins in a quantum dot.
It is shown that the nuclear spin decoherence time decreases by two orders of magnitude on occupying an empty quantum dot with a single electron, recovering to its original value for two electrons.
Improving a Solid-State Qubit through an Engineered Mesoscopic Environment.
This work prepares the quantum-dot nuclei under the feedback of coherent population trapping and observes their evolution from a thermal to a reduced-entropy state, with the immediate consequence of extended qubit coherence.

We investigate decoherence due to pure dephasing of a localized spin qubit interacting with a nuclear spin bath. Although in the limit of a very large magnetic field the only decoherence mechanism is
