We are pleased to welcome Prof Frank Wang from the University of Kent School of Computing to give a talk within the PQM discussion group on 21 Jan 2026. He will be speaking on the topic of:
Magneton-Mediated Quantum Computing
The Bohr magneton is the smallest unit of magnetism and can potentially serve as the most energy-efficient information carrier. In our recent ACM Transactions on Quantum Computing and IEEE Transactions on Quantum Engineering publications, we used a magnetic spin-spin interaction experiment to verify an ion-trapped quantum computing paradigm that approaches the Heisenberg limit for reversible operations and the Landauer bound for irreversible operations. Adhering to DiVincenzo’s five criteria for the physical implementation of a quantum computer, this paradigm offers several unique and attractive advantages: 1) high energy efficiency (by approaching the ultimate physical limits); 2) high-density integration (with just one ion/atom per qubit); 3) long coherence times (tens of seconds); 4) high-fidelity operations (98%); and 5) fault tolerance (through Decoherence-free Subspaces).
