Talk Title:  “Progress Towards a 100 Qubit Quantum Computer”


We are working to build and control a quantum information processor whose complexity exceeds that which can be fully simulated on a classical computer. The processor is based on nodes of nuclear spins that are locally controlled via an individually addressable electron spin.  The electron spins can be efficiently reset through their interactions with a high quality factor, superconducting resonator, and so we are able to remove entropy in parallel across the processor. The processor is planned to have two modes of operation: a small (50+) qubit processor and a tiled quantum simulator.  The spin processor is built from a Langmuir-Blodgett film, a 2-D crystal of organic free radicals that is 1 molecule thick.  Both modes of operation are based on ensembles of processors that are tiled in 2D.  While we give up the ability to perform a local operation based on a measurement of a single qubit, but since we retain the ability to remove entropy error correction remains possible.

I will describe recent progress in developing the instrumentation to enable this processor and what I believe are the near term prospects.
