Quantum Optics with Near-Lifetime-Limited Quantum-Dot Transitions in a Nanophotonic Waveguide.

Establishing a highly efficient photon-emitter interface where the intrinsic linewidth broadening is limited solely by spontaneous emission is a key step in quantum optics. It opens a pathway to coherent light-matter interaction for, e.g., the generation of highly indistinguishable photons, few-photon optical nonlinearities, and photon-emitter quantum gates. However, residual broadening mechani...

Fabrication of a nanophotonic quantum dot waveguide and photodetector integrated device

The authors present the design and fabrication of a nanophotonic waveguide and photodetector integrated device by molecular self-assembly of nanocrystal quantum dots (QD) and two different nano-gap formation techniques, namely electromigration-induced break-junction technique and electron beam lithography nano-gap patterning. A QD waveguide with 50 nm width integrated with a nano-scale QD photo...

Voltage-Controlled Entanglement between Quantum- Dot Molecule and its Spontaneous Emission Fields via Quantum Entropy

The time evolution of the quantum entropy in a coherently driven threelevel quantum dot (QD) molecule is investigated. The entanglement of quantum dot molecule and its spontaneous emission field is coherently controlled by the gat voltage and the intensity of applied field. It is shown that the degree of entanglement between a three-level quantum dot molecule and its spontaneous emission fields...
