“…Quantum lidar technology can also provide enhanced performance in imaging applications using entangled single photons [232]. Furthermore, atomic quantum sensors that use the quantum mechanical principles of light‐matter interaction can be used to build highly sensitive RF sensors [233]. Compared to conventional dipole‐antennas, the RF atomic sensors could provide accurate and high‐sensitivity electric field measurements that can be used to build improved receivers for radar and communication applications in future 6G networks [234].…”

The quantum internet is a cutting‐edge paradigm that uses the unique characteristics of quantum technology to radically alter communication networks. This new network type is expected to collaborate with 6G networks, creating a synergy that will fundamentally alter how we communicate, engage, and trade information. The improved security, increased speed, and increased network capacity of the quantum internet will lead to the emergence of a broad variety of new applications and services. The current state of quantum technology and its integration with 6G networks are summarised in this study, with an emphasis on the key challenges and untapped possibilities. The main goal is to get knowledge about how the quantum internet might impact communication in the future and alter several economic and societal sectors.

“…Using the mixer method [175] to determine phase of an incident RF electric field, Robinson, et al demonstrated an angle of arrival measurement wherein two spatial locations inside the vapor cell were probed to determine the phase angle of the incident plane-wave field [179]. This concept was then extended by scanning a single-point Rydberg atom receiver over a SA to determine the spatial distribution of phase in the plane of measurement and to extract a set of angles of arrival [180]. The SA measurement was an early study in understanding the use of these receivers in such measurements, ultimately to be used in channel sounding.…”

Rapid developments in synthetic aperture (SA) systems, which generate a larger aperture with greater angular resolution than is inherently possible from the physical dimensions of a single sensor alone, are leading to novel research avenues in several signal processing applications. The SAs may either use a mechanical positioner to move an antenna through space or deploy a distributed network of sensors. With the advent of new hardware technologies, the SAs tend to be denser nowadays. The recent opening of higher frequency bands has led to wide SA bandwidths. In general, new techniques and setups are required to harness the potential of wide SAs in space and bandwidth. Herein, we provide a brief overview of emerging signal processing trends in such spatially and spectrally wideband SA systems. This guide is intended to aid newcomers in navigating the most critical issues in SA analysis and further supports the development of new theories in the field. In particular, we cover the theoretical framework and practical underpinnings of wideband SA radar, channel sounding, sonar, radiometry, and optical applications. Apart from the classical SA applications, we also discuss the quantum electric-field-sensing probes in SAs that are currently undergoing active research but remain at nascent stages of development.

“…[1,2] Based on the Rydberg atomic system, in recent years, many researchers have demonstrated a new method of measuring the electric (E) field by using the electromagnetically induced transparency (EIT) and Autler-Townes (AT) splitting, which can be directly traced to the International System of Units (SI). [3][4][5][6][7][8][9][10] The EIT is a typical quantum interference effect that the atoms become transparent to the probe laser transmission in the presence of strongly coupled light. When the microwave (MW) E-field that resonates with the Rydberg atomic transition frequency is applied, the EIT spectrum will split proportionally to the power of the field.…”

The strength of microwave (MW) electric field can be observed with high precision using the standard EIT-AT techniques, when its frequency is resonant or near-resonant with the Rydberg transition frequency. As the detuning of MW field increases, the one of the transmission peaks (single peak) is easier to measure due to its increased amplitude. It can be found that the central symmetry point of the two transmission peaks f 1/2 is only related to the detuning of MW field △ MW and central symmetry points f 0 of resonant MW field, satisfying the relation f 1/2=△ MW /2+f 0. Thus, we demonstrate a single transmission peak method that the MW E-field can be determined by interval between the position of single peak and f 1/2. We use this approach to achieve the measurement of continuous frequencies ± 200 MHz bands of the MW field. The experimental results and theoretical analysis are presented to describe the effectiveness of this method. For 50 MHz < ΔMW <200 MHz, this method solves the problem that the AT splitting cannot be measured using the standard EIT-AT techniques and multiple atomic-level Rydberg atom schemes.
