Project funded by Carlsberg Foundation (Internationalisation Fellowships), grant CF24-0448. Participating organisations named by the source: Chalmers University of Technology. Runs n/a to 2026-08-30.

Just like regular computers, and indeed any information processing device, emerging quantum computers will require memory in order to realise their expansive promise. In this project I will develop a novel working memory for a quantum computer akin to RAM in regular computers, storing quantum information in the motion of a very slowly decaying, nanoscale mechanical resonator. Why? We are currently in an era reminiscent of the development of the computer - this time the technological breakthrough concerns harnessing quantum physics for computation. Already, proposed utilities enabled by a fully-fledged quantum computer range from faster design of new medicine and vaccines, over more efficient energy storage for a post-fossil fuel world, to a new cyber-security paradigm. How? I will combine recent advances in mechanical resonator design, materials, and functionalisation into a novel device, which enables coupling between a long-lived GHz-frequency mode of a nano-mechanical resonator and a superconducting circuit. This circuit will be composed of a microwave cavity to address the mechanical oscillator, and a qubit, whose state the mechanical resonator can store.
