Photonic quantum walks with symmetry protected topological phases

2017 · AIP conference proceedings

We experimentally study the effect of the lattice topology on photonic quantum walks. We generate correlated photon pairs in an array of silicon nanowaveguides making use of the high-nonlinearity available in the system. By using …

The boundary for quantum advantage in Gaussian boson sampling

2022 · Science Advances

Identifying the boundary beyond which quantum machines provide a computational advantage over their classical counterparts is a crucial step in charting their usefulness. Gaussian boson sampling (GBS), in which photons are measured from a highly …
