Our recent work on 'Limits to Quantum Gate Fidelity from Near-Field Thermal and Vacuum Fluctuations' has been published in Physical Review Applied. We develop a framework to analyze and engineer near-field thermal and vacuum fluctuations in the quantum computing hardware for achieving high-fidelity quantum gate operations.
We considered two promising spin-qubit-based quantum computing systems: (a) the silicon quantum dot system and (b) nitrogen-vacancy centers in diamond. Our work leverages advances in computational electromagnetics and open quantum systems and provides directions for device engineering for quantum computing processors.
