Quantum Computing and Visualization: A Disruptive Technological Change Ahead
E. .. Bethel, Mercy G. Amankwah, Jan Balewski +4 more·Oct 7, 2023
The focus of this Visualization Viewpoints article is to provide some background on quantum computing (QC), to explore ideas related to how visualization helps in understanding QC, and examine how QC might be useful for visualization with the growth ...
Machine learning for efficient generation of universal photonic quantum computing resources
Amanuel Anteneh, Olivier Pfister·Oct 4, 2023
We present numerical simulations of deep reinforcement learning on a measurement-based quantum processor--a time-multiplexed optical circuit sampled by photon-number-resolving detection--and find it generates squeezed cat states with an average succe...

Miha Papič, J. Tuorila, Adrian Auer +2 more·Sep 29, 2023
Enhancing the performance of noisy quantum processors requires improving our understanding of error mechanisms and the ways to overcome them. A judicious selection of qubit design parameters plays a pivotal role in improving the performance of quantu...
QonFusion - Quantum Approaches to Gaussian Random Variables: Applications in Stable Diffusion and Brownian Motion
Shlomo Kashani·Sep 28, 2023
In the present study, we delineate a strategy focused on non-parametric quantum circuits for the generation of Gaussian random variables (GRVs). This quantum-centric approach serves as a substitute for conventional pseudorandom number generators (PRN...

Sachleen Singh, B. Sephton, Wagner Tavares Buono +3 more·Sep 23, 2023
Abstract. Structured light, where complex optical fields are tailored in all their degrees of freedom, has become highly topical of late, advanced by a sophisticated toolkit comprising both linear and nonlinear optics. Removing undesired structure fr...
Reducing hardware requirements for entanglement distribution via joint hardware-protocol optimization
Adrià Labay Mora, Francisco Ferreira da Silva, Stephanie Wehner·Sep 20, 2023
We conduct a numerical investigation of fiber-based entanglement distribution over distances of up to 1600 km using a chain of processing-node quantum repeaters. We determine minimal hardware requirements while simultaneously optimizing over protocol...
