geller theory group

We are interested in several areas of theoretical physics and are currently focused primarily on quantum computation. We are especially interested in the design and use of the first generation of quantum computers and work closely with the UCSB superconducting quantum computation group of John Martinis and Andrew Cleland. Our work is currently supported by the NSF and IARPA.
