Photonic quantum simulations of coupled -symmetric Hamiltonians
Nicola Maraviglia, Patrick Yard, Ross Wakefield +9
Parity-time () symmetric Hamiltonians are generally non-Hermitian and give rise to exotic behaviour in quantum systems at exceptional points, where eigenvectors coalesce. The r…
Generation and sampling of quantum states of light in a silicon chip
Stefano Paesani, Yunhong Ding, Raffaele Santagati +7
Implementing large instances of quantum algorithms requires the processing of many quantum information carriers in a hardware platform that supports the integration of different co…
Simulating arbitrary Gaussian circuits with linear optics
Levon Chakhmakhchyan, Nicolas J. Cerf
Linear canonical transformations of bosonic modes correspond to Gaussian unitaries, which comprise passive linear-optical transformations as effected by a multiport passive interfe…
Boson sampling with Gaussian measurements
Levon Chakhmakhchyan, Nicolas J. Cerf
We develop an alternative boson sampling model operating on single-photon states followed by linear interferometry and Gaussian measurements. The hardness proof for simulating such…
Direct dialling of Haar random unitary matrices
Nicholas J. Russell, Levon Chakhmakhchyan, Jeremy L. O'Brien +1
Random unitary matrices find a number of applications in quantum information science, and are central to the recently defined boson sampling algorithm for photons in linear optics.…
Generation of entanglement in systems of intercoupled qubits
Levon Chakhmakhchyan, Claude Leroy, Nerses Ananikian +1
We consider systems of two and three qubits, mutually coupled by Heisenberg-type exchange interaction and interacting with external laser fields. We show that these systems allow o…
