Experimentally finding dense subgraphs using a time-bin encoded Gaussian boson sampling device
S. Sempere-Llagostera, R. B. Patel, I. A. Walmsley +1
Gaussian Boson Sampling (GBS) is a quantum computing concept based on drawing samples from a multimode nonclassical Gaussian state using photon-number resolving detectors. It was i…

A remarkable aspect of quantum theory is that certain measurement outcomes are entirely unpredictable to all possible observers. Such quantum events can be harnessed to generate nu…
Quantum interference enables constant-time quantum information processing
M. Stobińska, A. Buraczewski, M. Moore +8
It is an open question how fast information processing can be performed and whether quantum effects can speed up the best existing solutions. Signal extraction, analysis and compre…

Leonardo Banchi, W. Steven Kolthammer, M. S. Kim
Determining an unknown quantum state from an ensemble of identical systems is a fundamental, yet experimentally demanding, task in quantum science. Here we study the number of meas…

Michael Lubasch, Antonio A. Valido, Jelmer J. Renema +5
The current shift in the quantum optics community towards large-size experiments -- with many modes and photons -- necessitates new classical simulation techniques that go beyond t…

We develop a nonclassicality criterion for the interference of three delayed, but otherwise identical, light fields in a three-mode Bell interferometer. We do so by comparing the p…
