Superconducting Quantum Computing

A microfabricated superconducting qubit circuit.

By cooling superconducting circuits 10,000 times closer to absolute zero we observe quantized energy states, analogous to those of an atom.  While the states of an atom can be described in terms of their position, the states of the superconducting circuit can be described by variables such as charge and magnetic flux.  The lowest energy states form quantum bits (qubits), which exhibit quantum coherence described by the laws of quantum mechanics unlike classical bits in the computers used today.  In this laboratory we are interested in new ways to enhance coherence and measure these qubits.
