Recently, we proposed polariton lattices as a new platform for analogue simulation. Polariton lattices benefit by the continuous optical readout of the phase, energy, momentum and spin of the individual polariton vertices, the strong inter-particle interactions −mediated through the exciton component−, room temperature operation −with appropriate choice of materials−, and even the potential for electrical injection utilizing well-developed semiconductor technologies.

In this project, we will investigate experimentally the quantum speed-up of polariton simulators in realising the ground state of the XY Hamiltonian. Whereas for a classical simulator the time it takes to find the global minimum of the cost function of the problem increases exponentially with the number of degrees of freedom of the system, in a quantum simulator there is a polynomial increase of the time. Unravelling the mechanism of quantum speed-up is at the core of the fundamental physics underpinning polariton simulators.

Inverse scattering problems, namely reconstructing the shape of objects from their scattered intensity distributions occur in many fields of science and technology, such as tomographic imaging (MRI, CT scan), seismology, single shot X-ray scattering and imaging. Solving the inverse scattering problem, in cases where all the phase information is lost, is generally very difficult. This difficulty is alleviated by resorting to some a priori knowledge such as the boundaries within which the object lies (compact support), sparsity or other spatial features. Under such “restrictions”, it is possible to reconstruct the object using iterative algorithms, such as the well-known Gerchberg-Saxton algorithm. Unfortunately, the algorithms are time consuming and do not always converge to the right solution even with advanced computational resources. In this project, we will design and realise a polariton simulator to address inverse scattering problems with the aim to demonstrate solutions within the coherence lifetime of the polariton condensates (10ths of picoseconds; 6-9 orders of magnitude faster than current supercomputers).
