QCut, Quantum circuit-knitting on FiQCI in a nutshell

Come and learn the basics of quantum circuit-knitting, and how it can be utilised together with FiQCI and QCut, followed by a discussion on circuit-knitting and applications, for example, on parallel quantum computing.

Place: On-site at CSC, Life Science Center, Espoo and online

In the noisy intermediate scale quantum (NISQ) era of quantum computing the main factor limiting practical applications is the number of quality qubits available on a single quantum processing unit (QPU). For realising quantum utility, or even advantage on NISQ and future devices it would be useful to take a large quantum algorithm, cut it into smaller pieces, and distribute the pieces on separate QPUs for execution in parallel. This would allow circumventing some of the hardware limitations, especially concerning the number of qubits on NISQ devices. This is known as quantum circuit-knitting. So what can you do with it, what would be the applications of such a distributed quantum computing model, is this possible on FiQCI? Come and find out!

Target audience: everyone interested in quantum computing.
