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…
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…
Exact and approximate continuous-variable gate decompositions
Timjan Kalajdzievski, Nicolás Quesada
We gather and examine in detail gate decomposition techniques for continuous-variable quantum computers and also introduce some new techniques which expand on these methods. Both e…
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…
Training Gaussian Boson Sampling Distributions
Leonardo Banchi, Nicolás Quesada, Juan Miguel Arrazola
Gaussian Boson Sampling (GBS) is a near-term platform for photonic quantum computing. Applications have been developed which rely on directly programming GBS devices, but the abili…
Fast optimization of parametrized quantum optical circuits
Filippo M. Miatto, Nicolás Quesada
Parametrized quantum optical circuits are a class of quantum circuits in which the carriers of quantum information are photons and the gates are optical transformations. Classicall…
