Measurement and manipulation of qubits based on individual charges/spins in semiconductor quantum dots

The charge or spin degrees of freedom of an electron in semiconductor quantum dots are particularly attractive for the implementations of qubits. Experimental effort of measuring and manipulating individual charges/spins in quantum dots has generated considerable success and interest in the last several years. In this talk, I will describe our experiments at UCLA to measure spin-relaxation time and phase-coherence time of single spins in a Si spin qubit. I will also present results of an international collaboration that uses the Landau-Zener-Stucklberg interference to coherently manipulate a charge qubit on picosecond time scale.
