A Vision of Quantum-Centric Supercomputing

Abstract

Quantum computing systems continue to scale in size and quality. Furthermore, error resilience approaches start to enable interesting computational regimes opening what we call the era of quantum utility. In this era, the integration of quantum with HPC becomes critical to unlock the full potential of both technologies in a way that exceeds the capabilities of either one alone. Our vision for the path forward is quantum-centric supercomputing: quantum algorithms and routines supported by multiple quantum circuits with the aid of classical pre- and post-processing and classical high-performance elements. The development of tightly integrated systems with quantum and classical elements is essential for this vision. Not only will they provide an invaluable development framework for computational scientists, both quantum and classical, but they will also provide a testing ground for the joint optimization of classical and quantum resources needed to run utility scale hybrid workflows. Given the fast development of quantum technologies, we believe now is the time to bridge the gap between classical and quantum computing to define and shape a new era of supercomputing.
