Robust Visual Domain Randomization for Reinforcement Learning
Reda Bahi Slaoui, William R. Clements, Jakob N. Foerster +1
Producing agents that can generalize to a wide range of visually different environments is a significant challenge in reinforcement learning. One method for overcoming this issue i…
Exploratory Combinatorial Optimization with Reinforcement Learning
Thomas D. Barrett, William R. Clements, Jakob N. Foerster +1
Many real-world problems can be reduced to combinatorial optimization on a graph, where the subset or ordering of vertices that maximize some objective function must be found. With…
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…
Quantum simulations with multiphoton Fock states
T. Sturges, T. McDermott, A. Buraczewski +9
Quantum simulations are becoming an essential tool for studying complex phenomena, e.g. quantum topology, quantum information transfer, and relativistic wave equations, beyond the…
Estimating Risk and Uncertainty in Deep Reinforcement Learning
William R. Clements, Bastien Van Delft, Benoît-Marie Robaglia +2
Reinforcement learning agents are faced with two types of uncertainty. Epistemic uncertainty stems from limited data and is useful for exploration, whereas aleatoric uncertainty ar…
Quantum interference enables constant-time quantum information processing
M. Stobińska, A. Buraczewski, M. Moore +8
It is an open question how fast information processing can be performed and whether quantum effects can speed up the best existing solutions. Signal extraction, analysis and compre…
Modular Linear Optical Circuits
Paolo L. Mennea, William R. Clements, Devin H. Smith +8
We propose and demonstrate a modular architecture for reconfigurable on-chip linear-optical circuits. Each module contains 10 independent phase-controlled Mach-Zehnder interferomet…
Approximating Vibronic Spectroscopy with Imperfect Quantum Optics
William R. Clements, Jelmer J. Renema, Andreas Eckstein +7
We study the impact of experimental imperfections on a recently proposed protocol for performing quantum simulations of vibronic spectroscopy. Specifically, we propose a method for…
Efficient algorithm for boson sampling with partially distinguishable photons
Jelmer J. Renema, Adrian Menssen, William R. Clements +3
We demonstrate how boson sampling with photons of partial distinguishability can be expressed in terms of interference of fewer photons. We use this observation to propose a classi…
Implementing random unitaries in an imperfect photonic network
Roel Burgwal, William R. Clements, Devin H. Smith +4
We numerically investigate the implementation of Haar-random unitarity transformations and Fourier transformations in photonic devices consisting of beam splitters and phase shifte…
An Optimal Design for Universal Multiport Interferometers
William R. Clements, Peter C. Humphreys, Benjamin J. Metcalf +2
Universal multiport interferometers, which can be programmed to implement any linear transformation between multiple channels, are emerging as a powerful tool for both classical an…
