Abstract

We calculate and analyze the fields generated by two- and three-dimensional quantum antennas from identical independent two-level emitters. It is shown that two- and three-dimensional quantum antennas permit to achieve much better localization of the distribution of the emitted biphoton and three-photon field and its correlations than one-dimensional antennas. This makes two- and three-dimensional quantum antennas promising for quantum-radar applications.

We investigate the possibilities of quantum radars the radiating antennas of which consist of two interacting quantum dipoles in coherent or thermal states. It is shown that such asymmetric antennas allow us not only to reach super-resolution but also to overcome the “Rayleigh catastrophe”. In the case of a coherent antenna, an intensity measurement is sufficient to achieve these effects. In the thermal case, it is necessary to measure the temporal correlations of the field.

Shaping field correlations with quantum antennas

Alexander B. Mikhalychev, Dmitri S. Mogilevtsev, Gregory Ya. Slepyan +4 more

Quantum antennas can shape the spatial entanglement of emitted photons originating from specific initial non-Dicke entangled states of antenna emitters. In contrast to a classical antenna, a quantum antenna might not be affecting the amplitudes and intensities distribution of the field, but only shaping the second and higher order correlations. The shape and directivity of the correlations can be optimized using quantum state inference techniques. The character of the correlations can also be controlled by changing both the geometry and the initial state of the antenna. Positive and negative correlated twin-photons, as well as multi-photons entangled states can be produced from the same antenna for different initial states of the emitters. Our approach to antenna design can find applications in imaging and high-precision sensing, as well as in the development of an emitter-field interface for quantum information processing.

Synthesis of Quantum Antennas for Shaping Field Correlations

Alexander B. Mikhalychev, Dmitri S. Mogilevtsev, Gregory Ya. Slepyan +4 more

In studying the practical design of a quantum antenna with given spatial correlations, the authors show that the antenna's initial quantum state is at least as important as the spatial current distributions. Applying their state-inference procedure to a simple antenna (a linear one-dimensional array of equidistant quantum dots, trapped atoms, or superconducting qubits), they synthesize the initial states to generate drastically different emitted fields, for co- and contradirectionally entangled photons, complete suppression in the far field, or a nearly homogeneous far-field distribution---pointing to a host of applications in quantum optics and photonics.

Запрещенные углы излучения квантовых антенн

I. A. Peshko

A quantum antenna consisting of a set of two-level atoms situated on one straight line and prepared in different initial states is investigated. It is shown that if the initial state of a quantum antenna is a symmetric Dicke state, then for it a total suppression of radiation in definite directions is possible. Probability of simultaneous photon detections in these directions is equal to zero. This result is impossible for the pseudoclassical symmetric initial state of the antenna, which does not have quantum entanglement, and for such a state the probability of detecting a photon at any angle is always nonzero. The qualitative difference of the interference mechanism for the pseudo-classical and quantum antenna states is described.

Quantum antennas: From single-emitter coupling to metasurfaces and integrated quantum systems

Zahid Hassan, Archana T. Anilkumar, Praveen Kumar Sekhar

Abstract Quantum antennas couple localized quantum emitters to optical modes that can be collected, routed, and used in larger photonic systems. Their performance depends on photon delivery as well as single-photon purity, coherence, and indistinguishability. This Review connects the physics of light-matter interaction with the design of quantum-photonic interfaces. We compare semiconductor quantum dots, color centers, two-dimensional and molecular emitters, and examine plasmonic, dielectric, hybrid, cavity-coupled, and waveguideintegrated antenna architectures. We discuss how emitter position, dipole orientation, spectral matching, and material loss govern radiative enhancement and quenching, then assess performance through efficiency, brightness, photon statistics, and coupling to useful optical modes. Electromagnetic and quantum-optical modeling are considered alongside fabrication, deterministic emitter placement, and experimental characterization. We further examine how arrays and metasurfaces extend control to collective emission and quantum wavefronts, and survey applications in single-photon generation, communication, networking, computing, sensing, imaging, and ranging. Across these settings, rapid decay and strong local fields produce system-level gains only when useful photon delivery improves without compromising quantum-state quality. Low-loss design, spectral stabilization, reproducible integration, and complete photon-budget reporting emerge as priorities for scalable quantum-antenna platforms.
