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…
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…
Testing multi-photon interference on a silicon chip
Bryn A. Bell, Guillaume S. Thekkadath, Renyou Ge +2
Multi-photon interference in large multi-port interferometers is key to linear optical quantum computing and in particular to boson sampling. Silicon photonics enables complex inte…
Engineering Schrödinger cat states with a photonic even-parity detector
G. S. Thekkadath, B. A. Bell, I. A. Walmsley +1
When two equal photon-number states are combined on a balanced beam splitter, both output ports of the beam splitter contain only even numbers of photons. Consider the time-reversa…
Tuning between photon-number and quadrature measurements with weak-field homodyne detection
G. S. Thekkadath, D. S. Phillips, J. F. F. Bulmer +10
Variable measurement operators enable the optimization of strategies for testing quantum properties and the preparation of a range of quantum states. Here, we experimentally implem…
