Quantum circuits with many photons on a programmable nanophotonic chip
J. M. Arrazola, V. Bergholm, K. Brádler +36
Growing interest in quantum computing for practical applications has led to a surge in the availability of programmable machines for executing quantum algorithms. Present day photo…
Efficient sampling from shallow Gaussian quantum-optical circuits with local interactions
Haoyu Qi, Diego Cifuentes, Kamil Brádler +3
We prove that a classical computer can efficiently sample from the photon-number probability distribution of a Gaussian state prepared by using an optical circuit that is shallow a…
Balancing Accuracy and Complexity in Optimisation Models of Distributed Energy Systems and Microgrids with Optimal Power Flow: A Review
Ishanki A. De Mel, Oleksiy V. Klymenko, Michael Short
Optimisation and simulation models for the design and operation of grid-connected distributed energy systems (DES) often exclude the inherent nonlinearities related to power flow a…
A duality at the heart of Gaussian boson sampling
Kamil Bradler, Robert Israel, Maria Schuld +1
Gaussian boson sampling (GBS) is a near-term quantum computation framework that is believed to be classically intractable, but yet rich of potential applications. In this paper we…
A quantum hardware-induced graph kernel based on Gaussian Boson Sampling
Maria Schuld, Kamil Brádler, Robert Israel +2
A device called a 'Gaussian Boson Sampler' has initially been proposed as a near-term demonstration of classically intractable quantum computation. As recently shown, it can also b…
Nonnegativity for hafnians of certain matrices
Kamil Bradler, Shmuel Friedland, Robert Israel
We show that a complex symmetric matrix of the form where is Hermitian positive semidefinite, has a nonne…
Mapping constrained optimization problems to quantum annealing with application to fault diagnosis
Zhengbing Bian, Fabian Chudak, Robert Israel +3
Current quantum annealing (QA) hardware suffers from practical limitations such as finite temperature, sparse connectivity, small qubit numbers, and control error. We propose new a…
