James Meech University of Cambridge

Designing, Building, Evaluating, and Commercializing a Domain-Specific Computing Accelerator for Monte Carlo Simulation

Computer architects can no-longer rely upon Moore's law and Dennard scaling to run programs faster and more efficiently on digital electronic hardware. Building domain specific computing accelerators for applications such as Monte Carlo simulations can unlock speed and efficiency improvements. Monte Carlo simulations are slow and inefficient due to the repeated sampling of random numbers from non-uniform probability distributions and the propagation of those samples through equations. We designed and built a prototype accelerator for the Monte Carlo simulation sampling stage. We ran a set of C language benchmark programs over our accelerator and evaluated the number of clock cycles required to run each program and the accuracy of the results. The talk highlights a bottleneck that appears in many domain specific analog computing accelerator architectures. The talk concludes by enumerating some of the difficulties we encountered while attempting to commercialise our Monte Carlo simulation accelerator design.

Speaker's Bio

Meech completed his PhD in Domain-Specific Analog Physical Computing Accelerators in the Physical Computation Laboratory, Department of Engineering, University of Cambridge funded by the Centre for Doctoral Training in Sensor Technologies and Applications in 2023. During his PhD. Meech designed and built two computing accelerators. A fast and efficient programmable random variate accelerator and an optical Fourier transform computing accelerator. Meech was awarded the NanoFutures Leadership Fellowship 2023-2024 to attempt to commercialize programmable random variate accelerator work alongside a colleague. Prior to the PhD Meech received an MRes in Sensor Technologies and Applications from the University of Cambridge and an M.Eng in General Engineering from Durham University.

A versatile quantum playground with solid-state quantum emitters

Solid-state quantum emitters have attracted much attention as an integrated source of photonic and spin qubits, which are basic elements for a range of quantum applications. Recent advances in the generation, manipulation, and integration of these emitters have demonstrated a variety of quantum resources: bright quantum light sources, quantum memories, and spin-photon interfaces. In particular, controllable quantum emitters in photonic cavities or waveguides enable scalable quantum interactions between multiple photons and emitters. Given their high performance and scalability, quantum emitters are taking the next stages towards scalable, integrated quantum systems on photonic integrated circuits or fiber optics. Therefore, all quantum operations are efficiently possible in compact optics systems. In this talk, I introduce important challenges and recent races in scalable, integrated quantum photonics systems and new approaches to interfacing quantum emitters to commercial fiber platforms efficiently
