Student Support for Quantum Computing With Single Cooper-Pair Electronics

Abstract

This project supplies support for an additional graduate student on experimental investigation on quantum coherence, entanglement, and quantum computation in a solid-state, electronic realization of quantum bits based on superconducting single-electron devices, namely the single Cooper-pair box. Since these qubits can be microfabricated in large numbers on a single chip, addressed and coherently manipulated electronically, and then entangled with each other, they represent one of the most scalable implementations for possible quantum computers. A radio-frequency single electron transistor (RF-SET) is used for readout of the charge state of the qubit. Of particular importance in this scheme is an understanding and the control of the backaction of the measurement system, which can affect the lifetime and coherence of the qubit. Therefore, this backaction is studied with the goal of optimizing the sensitivity and lifetime in order to attain single-shot readout of the qubit.
