The technique of stimulated Raman adiabatic passage (STIRAP), which allows efficient and
selective population transfer between quantum states without suffering loss due to …

Fast, high efficiency and low error single-photon sources are required for the implementation
of a number of quantum information processing applications. The fastest triggered single …

A basic requirement for quantum information processing systems is the ability to completely
control the state of a single qubit,,,,,. For qubits based on electron spin, a universal single …

Manipulation of solid-state spin coherence is an important paradigm for quantum information
processing. Current systems either operate at very low temperatures or are difficult to scale …

Most schemes for quantum information processing require fast single-qubit operations. For
spin-based qubits, this involves performing arbitrary coherent rotations of the spin state on …

A review of coherent and collective quantum optical effects like superradiance and coherent
population trapping in mesoscopic systems is presented. Various new physical realizations …

We propose a quantum nondemolition method—a giant optical Faraday rotation near the
resonant regime to measure a single-electron spin in a quantum dot inside a microcavity …

We present an efficient quantum repeater protocol that uses coupled systems of quantum-
dot spins and optical microcavities, in which the spatial entanglement of a photon system …

We report on the coherent optical excitation of electron spin polarization in the ground state
of charged GaAs quantum dots via an intermediate charged exciton (trion) state. Coherent …

Electron spin coherence has been generated optically in n-type modulation doped (In, Ga)
As/GaAs quantum dots (QDs) which contain on average a single electron per dot. The …
