Special Issue Information

Dear Colleagues,

The interaction of non-classical light with solid-state nanosystems is a new, incredibly interesting and relevant direction of modern quantum physics. This area of inspiring research combines the quantum features of light- and nanoscale properties of matter arising due to spatial quantization and gives rise to new physical effects. The found effects are of great importance from a fundamental point of view and very promising for practical applications in quantum nanotechnology, nanoelectronics, quantum measurements, quantum optics, quantum computing, and information science.

Nanophotonics and nanoscale quantum optics provide precise manipulation of nano-object properties and at the same time open new possibilities of production, detection, and management of quantum light with channel light in a nanoscale volume. We are pleased to invite you to contribute to the Special Issue “Nanoscale Quantum Optics” which is generally focused on the development of novel methods and techniques to control the interaction between light and matter at a nanosize level and femtosecond timescales.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not be limited to) the following: single photon sources, generation and manipulation of quantum light on a chip, nanosystems in microcavity, excitation of nanostructures by quantum light, optical and electronic properties of 2D materials induced by quantum light, metamaterials as a tool for manipulating quantum light, novel techniques and development of defect color nanophotonics, atom–photon quantum interface, correlations, entanglement and hybrid systems, superconducting devices for few-photon generation and conversion, and high time and scale resolution quantum measurements.

We look forward to receiving your contributions.

The imitative modelling of processes in the brain of living beings is an ambitious task. However, advances in the complexity of existing hardware brain models are limited by their low speed and high energy consumption. A superconducting circuit with Josephson junctions closely mimics the neuronal membrane with channels involved in the operation of the sodium-potassium pump. The dynamic processes in such a system are characterised by a duration of picoseconds and an energy level of attojoules. In this work, two superconducting models of a biological neuron are studied. New modes of their operation are identified, including the so-called bursting mode, which plays an important role in biological neural networks. The possibility of switching between different modes in situ is shown, providing the possibility of dynamic control of the system. A synaptic connection that mimics the short-term potentiation of a biological synapse is developed and demonstrated. Finally, the simplest two-neuron chain comprising the proposed bio-inspired components is simulated, and the prospects of superconducting hardware biosimilars are briefly discussed. Full article

We have theoretically studied the transport properties of the SIsNSOF structure consisting of thick (S) and thin (s) films of superconductor, an insulator layer (I), a thin film of normal metal with spin–orbit interaction (SOI) (NSO), and a monodomain ferromagnetic layer (F). The interplay between superconductivity, ferromagnetism, and spin–orbit interaction allows the critical current of this Josephson junction to be smoothly varied over a wide range by rotating the magnetization direction in the single F-layer. We have studied the amplitude of the spin valve effect and found the optimal ranges of parameters. Full article

Optimal design of a silicon nitride waveguide structure composed of resonant nanoantennas for efficient light coupling with interlayer exciton emitters in a MoSe2–WSe2 heterostructure is proposed. Numerical simulations demonstrate up to eight times coupling efficiency improvement and twelve times Purcell effect enhancement in comparison with a conventional strip waveguide. Achieved results can be beneficial for development of on-chip non-classical light sources. Full article
