Efficient sampling from shallow Gaussian quantum-optical circuits with local interactions

Haoyu Qi, Diego Cifuentes, Kamil Brádler +3

We prove that a classical computer can efficiently sample from the photon-number probability distribution of a Gaussian state prepared by using an optical circuit that is shallow a…

A quantum hardware-induced graph kernel based on Gaussian Boson Sampling

Maria Schuld, Kamil Brádler, Robert Israel +2

A device called a 'Gaussian Boson Sampler' has initially been proposed as a near-term demonstration of classically intractable quantum computation. As recently shown, it can also b…

A Quantum Approximate Optimization Algorithm for continuous problems

Guillaume Verdon, Juan Miguel Arrazola, Kamil Brádler +1

We introduce a quantum approximate optimization algorithm (QAOA) for continuous optimization. The algorithm is based on the dynamics of a quantum system moving in an energy potenti…
