Quantum control and quantum information processing with a superconducting cavity
Abstract: We propose an efficient protocol to perform universal quantum control of an oscillator mode (e.g. cavity mode) off-resonantly coupled to an ancillary qubit. With an excitation number trunca...

Two-dimensional trapped ion crystals, micromotion and qubit state detection
Abstract: To study potential avenues for scaling up trapped ion crystal size, we built a modified Paul trap with an oblate aspect ratio designed for trapping radial 2-d ion crystals. In this geometry...
