Size Uniformity of CsPbBr₃ Perovskite Quantum Dots via Manganese-Doping

Nanomaterials
The achievement of size uniformity and monodispersity in perovskite quantum dots (QDs) requires the implementation of precise temperature control and the establishment of optimal reaction conditions.

High power ultrafast phase-locked laser at 2060 nm from a doubly resonant optical parametric oscillator

Scientific Reports
A high-power 2- $$\mu$$ m phase-locked femtosecond source is demonstrated by a degenerate doubly resonant optical parametric oscillator (DROPO), which is synchronously pumped by a home-built Yb:YAG Kerr-lens mode-locked thin-disk laser.

Quantum optical Fredkin gate [PDF]

Physical Review Letters, 1989
A simple optical model to realize a reversible, potentially error-free logic gate a Fredkin gate is discussed. The device dissipates no energy and makes use of the Kerr nonlinearity to produce intensity-dependent phase shifts. The analysis shows that quantum mechanics permits the operation of error-free logic gates which dissipate no energy.

Subjective nature of path information in quantum mechanics

Nature Communications
Common sense suggests that a particle must have a definite origin if its full path information is available. In quantum mechanics, the knowledge of path information is captured through the well-established duality relation between path distinguishability

Quantum Computation with Linear Optics

, 1999
We present a constructive method to translate small quantum circuits into their optical analogues, using linear components of present-day quantum optics technology only. These optical circuits perform precisely the computation that the quantum circuits are designed for, and can thus be used to test the performance of quantum algorithms.

Distribution of high-dimensional entanglement via an intra-city free-space link

Nature Communications, 2017
Increasing the dimensionality of entangled states improves robustness and capacity of secure quantum communications, but it requires suitably modified setups.
