Biphoton entanglement of topologically-distinct modes
Cooper Doyle, Wei-Wei Zhang, Michelle Wang +3
The robust generation and manipulation of entangled multiphoton states on-chip has an essential role in quantum computation and communication. Lattice topology has emerged as a mea…
Experimental demonstration of Gaussian boson sampling with displacement
G. S. Thekkadath, S. Sempere-Llagostera, B. A. Bell +3
Gaussian boson sampling (GBS) is quantum sampling task in which one has to draw samples from the photon-number distribution of a large-dimensional nonclassical squeezed state of li…
Single-shot discrimination of coherent states beyond the standard quantum limit
G. S. Thekkadath, S. Sempere-Llagostera, B. A. Bell +3
The discrimination of coherent states is a key task in optical communication and quantum key distribution protocols. In this work, we use a photon-number-resolving detector, the tr…
Quadratic speedup for simulating Gaussian boson sampling
Nicolás Quesada, Rachel S. Chadwick, Bryn A. Bell +4
We introduce an algorithm for the classical simulation of Gaussian boson sampling that is quadratically faster than previously known methods. The complexity of the algorithm is exp…
Diagnosing phase correlations in the joint spectrum of parametric downconversion using multi-photon emission
Bryn A. Bell, Gil Triginer Garces, Ian A. Walmsley
The development of new quantum light sources requires robust and convenient methods of characterizing their joint spectral properties. Measuring the joint spectral intensity betwee…
Quantum-enhanced interferometry with large heralded photon-number states
G. S. Thekkadath, M. E. Mycroft, B. A. Bell +11
Quantum phenomena such as entanglement can improve fundamental limits on the sensitivity of a measurement probe. In optical interferometry, a probe consisting of entangled phot…
