Invited talk

The nitrogen-vacancy (NV) center in diamond exists in different charge states with distinct photoluminescence properties, which are sensitive to the nanoscale electrochemical environment. Hence, the NV charge state is emerging as a powerful all-optical platform for nanoscale sensing and imaging. Although significant progress has been made in engineering near-surface NV centers in bulk diamond,...

Fault-tolerant quantum computers have the potential to enable predictive simulations of strongly correlated materials beyond the capabilities of classical computation. However, connecting realistic electronic structure calculations to concrete fault-tolerant resource estimates remains an open challenge. In this work, we present an end-to-end workflow that bridges this gap, beginning with ab...

Potassium-39 has several broad Feshbach resonances that enable the interatomic interaction to be precisely tuned over a wide range of values. In recent years the |1, -1> Feshbach resonance at 33.6 G has been widely used to create 39K BECs because of its convenience, especially in experiments conducted in space.
We have found that the position of the 33.6 G Feshbach resonance can shift by as...

In equity markets, many risks do not arise from individual stocks in isolation, but from shared price movements, high return correlations, similar sector exposures, and comparable sensitivities to common risk factors. Stock clustering can help reveal latent groups of equities that may react similarly to market shocks, enabling investors to detect hidden risk concentrations, assess whether a...

The Quantum Approximate Optimisation Algorithm (QAOA) tackles combinatorial optimisation problems by encoding their solutions into the ground state of an Ising Hamiltonian prepared by a $p$-level parameterised circuit, with the angles tuned classically. Parameter optimisation is widely regarded as a central bottleneck, and worst-case results showing that training QAOA is NP-hard are often read...
