Mike Geller: Quantum Information Processing with Prethreshold Superconducting Qubits Export this event to calendar

Monday, November 8, 2010 — 12:30 PM to 1:30 PM EST

Mike Geller, University of Georgia

I will discuss an alternative approach to quantum computation and simulation that is ideally suited for today's sub-threshold-fidelity qubits, especially in superconducting architectures. This approach makes use of the the n-dimensional  single-excitation subspace (SES) of a system of n tunably coupled qubits. Although technically unscalable and inefficient in terms of the number of qubits required, the SES approach allows n-dimensional unitary operations to be implemented in a single shot, without the need to decompose into gates. The real power of this approach is probably in its application to quantum simulation, and I will show that for a particular class of time-dependent quantum simulation problems a practical device that would vastly outperform classical machines is within experimental reach.
