Superconducting Qubits featured in Physics Today

This photo by our own Erik Lucero graced the cover of the July 2009 issue of Physics Today, along with a feature article about superconducting qubits. The article discusses our work on arbitrary state generation in a harmonic oscillator (Hofheinz et al., Nature 459, 546-549 (2009). See publications.) as well as work from the Schoelkopf group at Yale.

Current Research

Our research goal is to build a quantum computer using superconductors. Much of our effort is devoted to understanding the basic physics of decoherence (error) mechanisms in Josephson junction devices. Pictured below is a wafer with test dies that we use to measure two-qubit logic gates.

Our group is part of the California Nanosystems Institute.
