QUANTUM DYNAMICS AND NONLINEAR DYNAMICS
We are investigating the behaviour of quantum systems which are promising candidates
for the development of future quantum technologies, such as quantum computers and
quantum sensors. These include the theoretical investigation of how quantum
spins qubits interact with the surrounding environment which causes the qubit to lose its quantum
coherence. Often the environment can be itself a collection of other quantum spins and decoherence
by a quantum bath can be rather different from decoherence by classical noise.
One example are hybrid spin electronic-nuclear qubits
where we have shown theoretically that the coherence times can vary by orders of magnitude at certain
optimal working points. We are part of the UCL quantum
information group and collaborate with experimental groups at the London Centre for Nanotechnology.
We are also investigating the theory of optomechanical cooling of small mechanical resonators into the
quantum ground state, in particular of small silica spheres and nanodiamonds levitated in optical fields.
This project is a collaboration with the optomechanics group currently implementing
experimental realisations of levitated systems .
There are potential Phd opportunities in the following areas:
(1) Optomechanics: towards sensing at the quantum limit
(2) Quantum spin dynamics: suppressing decoherence by quantum spin baths
There is also a 12 month post-doctoral or visitor position currently open in either of these two areas
We welcome enquiries from prospective PhD students or other researchers and visitors.
