Quantum State Holography

We introduce a novel method for reconstructing quantum superposition states excited in molecules or atoms by short laser pulses. The technique is based on mixing the unknown object state with a known reference state generated in the same system by an additional delayed laser pulse, and detecting the total time-and frequency-integrated uorescence as a function of the delay. We demonstrate the fe...

Quantum coherence and lifetimes of surface-state electrons

We discuss a novel approach to measure the electron phase-relaxation length and femtosecond lifetimes at surfaces. It relies on the study of the spatial decay of quantum interference patterns in the local density of states (LDOS) with the STM. The method has been applied to s–p derived surface-state electrons on Cu(111) and Ag(111). The characteristic decay length of the LDOS oscillations is in...

Steady-state performance of microcavity surface-emitting lasers with quantum confinement of electrons and photons

In conventional surface-emitting lasers, the photon density of states is essentially that of a bulk material and, therefore, spontaneous emission rates are the same as in bulk. However, in an ideal laser, one would like to have a single photon mode coincident with the peak in the material gain so that zero-threshold lasing occurs. This possibility is examined for a surface-emitting microcavity ...

Electrons at the Surface of Quantum Systems

Electrons can be trapped at the surfaces and interfaces of the condensed phases of quantum matter (in particular hydrogen and helium), where they form classical two-dimensional Coulomb systems. Apart from studying the intrinsic properties of these nearly ideal systems, like the transition from an electron gas to a Wigner solid, one can use the electrons also as a sensitive probe to investigate ...

Quantum Computing with Steady State Spin Currents

Sutton, Brian M. M.S.E.C.E., Purdue University, December 2013. Quantum Computing with Steady State Spin Currents. Major Professor: Supriyo Datta. Many approaches to quantum computing use spatially confined qubits in the presence of dynamic fields to perform computation. These approaches are contrasted with proposals using mobile qubits in the presence of static fields. In this thesis, steady st...
