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 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…
A Quantum Approximate Optimization Algorithm for continuous problems
Guillaume Verdon, Juan Miguel Arrazola, Kamil Brádler +1
We introduce a quantum approximate optimization algorithm (QAOA) for continuous optimization. The algorithm is based on the dynamics of a quantum system moving in an energy potenti…
Linear multiport photonic interferometers: loss analysis of temporally-encoded architectures
Haoyu Qi, Lukas G. Helt, Daiqin Su +2
Implementing spatially-encoded universal linear multiport interferometers on integrated photonic platforms with high controllability becomes increasingly difficult as the number of…
Quantum precision of beam pointing
Haoyu Qi, Kamil Brádler, Christian Weedbrook +1
We consider estimating a small transverse displacement of an optical beam over a line-of-sight propagation path: a problem that has numerous important applications ranging from est…
Machine learning method for state preparation and gate synthesis on photonic quantum computers
Juan Miguel Arrazola, Thomas R. Bromley, Josh Izaac +3
We show how techniques from machine learning and optimization can be used to find circuits of photonic quantum computers that perform a desired transformation between input and out…
Implementing quantum algorithms on temporal photonic cluster states
Daiqin Su, Krishna Kumar Sabapathy, Casey R. Myers +3
Implementing quantum algorithms is essential for quantum computation. We study the implementation of three quantum algorithms by performing homodyne measurements on a two-dimension…
Correcting finite squeezing errors in continuous-variable cluster states
Daiqin Su, Christian Weedbrook, Kamil Brádler
We introduce an efficient scheme to correct errors due to the finite squeezing effects in continuous-variable cluster states. Specifically, we consider the typical situation where…
Gaussian Boson Sampling for perfect matchings of arbitrary graphs
Kamil Brádler, Pierre-Luc Dallaire-Demers, Patrick Rebentrost +2
A famously hard graph problem with a broad range of applications is computing the number of perfect matchings, that is the number of unique and complete pairings of the vertices of…
