Light trapping is a crucial mechanism for synchronization in optical communication. Especially on the level of single photons, control of the exact emission time is desirable. In this paper, a single‐photon buffering device composed of a quantum dot doped with a single Mn atom in a cavity is theoretically proposed. A method to detain a single cavity photon as an excitation of the dot is presented. The storage scheme is based on bright to dark exciton conversion performed with an off‐resonant… 


On-demand semiconductor single-photon source with near-unity indistinguishability.
Pulsed resonance fluorescence has been anticipated as the optimum condition for the deterministic generation of high-quality photons with vanishing effects of dephasing and is generated from a single, microcavity-embedded quantum dot under s-shell excitation with 3 ps laser pulses.
Spin control by ultra short laser pulses in a Mn doped quantum dot
Optically induced spin flip processes in quantum dots doped with a single Mn atom are discussed. On the femtosecond time scale the exciton can be controlled by ultra short laser pulses. Via the
Ultrafast optical control of individual quantum dot spin qubits.
The decoherence and dephasing mechanisms due to hyperfine interaction with the nuclear-spin bath are reviewed, and it is shown how the single-qubit operations can be combined to perform spin echo sequences that extend the qubit decoherent from a few nanoseconds to several microseconds, more than 5 orders of magnitude longer than the single qubit gate time.
A solid-state light–matter interface at the single-photon level
The coherent and reversible mapping of a light field with less than one photon per pulse onto an ensemble of ∼107 atoms naturally trapped in a solid is demonstrated by coherently absorbing the light field in a suitably prepared solid-state atomic medium.
Indistinguishable photons from a single-photon device
It is found that consecutive photons are largely indistinguishable, with a mean wave-packet overlap as large as 0.81, making this source useful in a variety of experiments in quantum optics and quantum information.
Triggered polarization-entangled photon pairs from a single quantum dot up to 30 K
The radiative biexciton-exciton decay in a semiconductor quantum dot (QD) has the potential of being a source of triggered polarization-entangled photon pairs. However, in most cases the
Coherent Control of Dark Excitons in Semiconductor Quantum Dots
We review studies of the quantum dot confined dark exciton and demonstrate its use as a matter qubit. The dark exciton is an optically forbidden semiconductor electronic excitation, in which an
Quantum dot single-photon sources with ultra-low multi-photon probability
High-quality sources of single photons are of paramount importance for quantum communication, sensing, and metrology. To these ends, resonantly excited two-level systems based on self-assembled
Quantum nature of a strongly coupled single quantum dot–cavity system
Observations unequivocally show that quantum information tasks are achievable in solid-state cavity QED by observing quantum correlations in photoluminescence from a photonic crystal nanocavity interacting with one, and only one, quantum dot located precisely at the cavity electric field maximum.
