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. More recently, the photo was featured again on the cover of Quantum Measurement and Control by Wiseman and Milburn.

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.
