Quantum simulation with just-in-time compilation

Abstract

We present a first attempt to perform circuit-based quantum simulation using the just-in-time (JIT) compilation technique on multiple hardware architectures and configurations based on singlenode central processing units (CPUs) and graphics processing units (GPUs). One of the major challenges in scientific code development is to balance the level of complexity between algorithms and programming techniques without losing performance or degrading code readability. In this context, we have developed qibojit: a new module for the Qibo quantum computing framework, which uses a just-in-time compilation approach through Python. We perform systematic performance benchmarks between our JIT approach and a subset of relevant publicly available libraries for quantum computing. We show that our novel approach simplifies the complex aspects of the implementation without deteriorating performance.

An open-source modular framework for quantum computing

“…Exhaustive performance benchmarks between the just-in-time and pre-compiled approaches for quantum simulation together with a technical explanation of techniques used to accellerate simulation performance are addressed in Sections II and III in Ref. [31].…”
