Electron Injection and Beam Dynamics in a Laser Wakefield Acceleration Driven by Laser Pulses Carrying Orbital Angular Momentum
Q. Qian, M. Li, Y. Ma +21
Laser pulses carrying orbital angular momentum (OAM) provide a new degree of freedom for controlling plasma-based accelerators. Here, we demonstrate experimentally laser wakefield…
A virtually connected probabilistic computer as a solver for higher-order, densely connected, or reconfigurable combinatorial optimisation problems
Amy J. Searle, Harry Youel, Fredrik Hasselgren +3
Recently, there has been growing interest in unconventional computing as an approach for solving NP-hard problems, by developing dedicated hardware to find solutions more efficient…
Self-correcting High-speed Opto-electronic Probabilistic Computer
Ramy Aboushelbaya, Annika Moslein, Hadi Azar +2
We present a novel self-correcting, high-speed optoelectronic probabilistic computer architecture that leverages source-device independent (SDI) quantum photonic p-bits integrated…
Probabilistic Computing Optimization of Complex Spin-Glass Topologies
Fredrik Hasselgren, Max O. Al-Hasso, Amy Searle +2
Spin glass systems as lattices of disordered magnets with random interactions have important implications within the theory of magnetization and applications to a wide-range of har…
A Probabilistic Computing Approach to the Closest Vector Problem for Lattice-Based Factoring
Max O. Al-Hasso, Marko von der Leyen
The closest vector problem (CVP) is a fundamental optimization problem in lattice-based cryptography and its conjectured hardness underpins the security of lattice-based cryptosyst…
