Macroscopic quantum phenomena, such as observed in superfluids and superconductors, have led to promising technological advancements and some of the most important tests of fundamental physics. At present, quantum detection of light is mostly relegated to the microscale, where avalanche photodiodes are very sensitive to distinguishing single-photon events from vacuum but cannot differentiate between larger photon-number events. Beyond this, the ability to perform measurements to resolve photon… 

Sample efficient graph classification using binary Gaussian boson sampling

This work presents a variation of a quantum algorithm for the machine learning task of classification with graph-structured data that implements a feature extraction strategy based on Gaussian boson sampling a near term model of quantum computing.

The boundary for quantum advantage in Gaussian boson sampling

A distribution is introduced that is efficient to sample from classically and that passes a variety of GBS validation methods, providing an important adversary for future experiments to test against, and reduces the run-time of classically simulating state-of-the-art GBS experiments to several months.

Non-Gaussian Quantum States and Where to Find Them

Gaussian states have played on important role in the physics of continuous-variable quantum systems. They are appealing for the experimental ease with which they can be produced, and for their

Quantum computational advantage using photons

Gaussian boson sampling was performed by sending 50 indistinguishable single-mode squeezed states into a 100-mode ultralow-loss interferometer with full connectivity and random matrix and sampling the output using 100 high-efficiency single-photon detectors, and the obtained samples were validated against plausible hypotheses exploiting thermal states, distinguishable photons, and uniform distribution.
