For quantum computers (QCs) to be truly effective, they must solve meaningful problems. Exploring how to scale their computational power is done in three notable ways.
First, hybrid High-Performance Computing-QC (HPC-QC) uses quantum computers as co-processors for computations where it offers an advantage. HPC-QC can both enhance the capabilities of current quantum devices and accelerate the performance of classical HPC systems in the future. It also increases accessibility to quantum technologies by leveraging existing HPC infrastructure and encouraging their adoption within HPC communities.
Second, combining QCs with AI: the advances in one can help overcome challenges in the other. For example, quantum algorithms may improve machine learning performance, while AI techniques can assist in optimising quantum circuits and error correction.
Third, connecting multiple QCs using a quantum communication network can enable to combine their computational resources. This modular or distributed architecture offers a path to scaling quantum systems beyond the limits of individual devices.
