Existing methods for the mass detection of viruses are limited to the registration of small amounts of a viral genome or specific protein markers. In spite of high sensitivity, the applied methods cannot distinguish between virulent virus particles and non-infectious virus particle debris. We report an approach to solve this long-standing challenge using the SARS-CoV-2 ...

A generalized model of the interaction of a superconducting qubit with the electromagnetic field of a cavity, which is conducted through capacitance (electric dipole interaction) and inductance (magnetic dipole interaction)—the anisotropic Rabi model—is considered. It has been shown that the Hilbert space of the anisotropic model can be split into two subspaces orthogonal in the ...

The history of the USSR is considered for the first time in a techno-political and socio-cultural perspective through the prism of the "energy of socialism". Based on the STS methodology, the social anthropology of technology and the cultural history of Russia, the interaction of major scientific and technical programs of the electrical, nuclear and oil ...

Entangled photon pairs are key to many novel applications in quantum technologies. Semiconductor quantum dots can be used as sources of on-demand, highly entangled photons. The fidelity to a fixed maximally entangled state is limited by the excitonic fine-structure splitting. This work demonstrates that, even if this splitting is absent, the degree of entanglement cannot ...

The on-demand preparation of higher-order Fock states is of fundamental importance in quantum information sciences. We propose and compare different protocols to generate higher-order Fock states in solid state quantum-dot–cavity systems. The protocols make use of a series of laser pulses to excite the quantum dot exciton and off-resonant pulses to control the detuning between ...

We have focused on the ability to tune the aluminum (Al) content of the AlGaAs alloy along the growth direction in inverted pyramids (by MOVPE), thus tailoring the potential along a QWR nanostructure. Three parabolic-potential QDs (PQDs) of different potential gradients have thus been realized. The parabolic profiles were changed systematically by fixing the minimum ...

Photoluminescence including fluorescence plays a great role in a wide variety of applications from biomedical sensing and imaging to optoelectronics. Therefore, the enhancement and control of photoluminescence has immense impact both on fundamental scientific research and aforementioned applications. Among various nanophotonic schemes and nanostructures to enhance the photoluminescence, we focus on a certain type of ...

Разработан метод анализа модификации спонтанного излучения в структурах с цилиндрической симметрией. Выведен метод матриц рассеяния для цилиндрических структур. На основе матриц рассеяния получены правила квантования электромагнитного поля (S-квантование) в цилиндрических системах. Получены общие выражения для темпа излучательной рекомбинации эмиттера, находящегося в произвольной точке структуры. Выведены количественные показатели, дающие оценку усилению и подавлению излучательной рекомбинации, которые ...

A Schrödinger-cat state is a coherent superposition of macroscopically distinguishable quantum states, in quantum optics usually realized as superposition of coherent states. Protocols to prepare photonic cats have been presented for atomic systems. Here we investigate in what manner and how well the preparation protocols can be transferred to a solid-state platform, namely, a semiconductor ...

In this work, we demonstrate the trapping of rubidium (Rb) atoms in a pulsed optical dipole trap formed by femtosecond laser radiation with a pulse duration as small as 70 fs. The atom localization in such trap strongly depends on the heating of the atoms caused by the momentum diffusion due to the dipole force ...

The concept of the Lorentz-invariant mass of a group of particles is shown to be applicable to biphoton states formed in the process of spontaneous parametric down conversion. The conditions are found when the Lorentz-invariant mass is related directly with (proportional to) the Schmidt parameter determining a high degree of entanglement of a biphoton state with ...

Данная работа посвящена моделированию оптического брэгговского фильтра для видимого диапазона на чипе. С применением моделирования получены основные характеристики брэгговского фильтра для видимого диапазона: центральная длина волны, коэффициент пропускания, полуширина вырезаемой мощности от геометрических размеров и количество периодов. Сделаны соответствующие выводы зависимости физических параметров брэгговского фильтра от геометрических, которые качественно совпадают с экспериментально полученными данными. ...

We have suggested and realized a giant asymmetry of the transmission of light propagating through a linear nonmagnetic optical system that consists of a nanohole in metal film deposited on the surface of a one-dimensional photonic crystal. The asymmetry of the light transmission is caused by two factors: (i) practical impossibility to reverse the wavefront ...

The localization and transport of a photon through a subwavelength hole with the help of a neutral atom are studied. A method proposed and realized in the study is based on the absorption of a photon by a neutral atom directly in front of a subwavelength hole, the flight of the atom through the hole, ...
