Space-time metallic metasurfaces for frequency conversion and beamforming

Salvador Moreno-Rodríguez, Antonio Alex-Amor, Pablo Padilla, Juan F. Valenzuela-Valdés, and Carlos Molero

Phys. Rev. Applied 21, 064018 (2024) - Published 7 June, 2024

This study details a class of metal-based metasurfaces that periodically alternate their properties in both space and time. The authors’ approach offers an alternative for simulating such metasurfaces, providing physical insight into the diffraction phenomenon. The analytical framework is based on the circuit equivalent of the physical structure, revealing important features such as scattering parameters, field profiles, diffraction angles, and the nature of space-time harmonics. The results of the study highlight the potential for these metasurfaces in beamformers or frequency mixers for wireless communication systems.

Excitonic Shockley-Read-Hall recombination in organic semiconductors

Noel C. Giebink and Stephen R. Forrest

Phys. Rev. Applied 21, 064019 (2024) - Published 10 June, 2024

Trap-mediated recombination influences the performance of a wide range of organic semiconductor devices, but it has so far been unclear how the well-known Shockley-Read-Hall (SRH) recombination rate expression extends to this class of materials. This study formalizes SRH recombination for organic semiconductors and shows how it is modified to account for the finite lifetime of the exciton intermediate state involved in their recombination process. This result is important in organic light-emitting diodes, where it identifies the relative host and dopant energetics in the emissive layer, which are needed to achieve ultralow voltage operation.

Noninvasive magnetocardiography of a living rat based on a diamond quantum sensor

Phys. Rev. Applied 21, 064028 (2024) - Published 12 June, 2024

Diamond-based nitrogen-vacancy (N- $V$ ) centers hold the potential to overcome the sensor limitations for magnetocardiography (MCG), but their invasive measurement scheme is incompatible with clinical settings. This study presents a noninvasive diamond MCG system based on N- $V$ center ensembles enhanced by techniques such as magnetic flux concentration, and demonstrates a practical instance of noninvasive MCG measurement on a living animal. These results mark a substantial step toward deploying diamond MCG in biophysical applications, highlighting its future potential in biomagnetic observations.

Parametric all-optical modulation on a chip

Zhan Li, Jiayang Chen, Zhaohui Ma, Chao Tang, Yong Meng Sua, and Yu-Ping Huang

Phys. Rev. Applied 21, 064049 (2024) - Published 21 June, 2024

The authors demonstrate all-optical modulation on a chip, which is important for scalable all-optical information processing and quantum computing, as it supports fan-out and cascaded operations. Using quantum Zeno blockade, logical operations are realized in an interaction-free manner, solely through parametric nonlinear optics. This scheme can thus be implemented at room temperature and on highly integrated chips, as opposed to approaches using single emitters, where cryogenic cooling is required.

Interferometry with few photons

Q. Pears Stefano, A.G. Magnoni, D. Rodrigues, J. Tiffenberg, and C. Iemmi

Phys. Rev. Applied 21, 064050 (2024) - Published 21 June, 2024

Optical phase determination using just a few photons is crucial for applications in biological imaging and quantum information processing, yet is hampered by shot noise from the source and readout noise from the sensor. Employing a skipper CCD, which can arbitrarily decrease readout noise, the authors investigate these noise sources individually and demonstrate a significant improvement in detection fidelity with reduced detector noise. With fewer than three photons per pixel, the accuracy of phase estimation suffers, regardless of detection noise. This insight highlights the skipper CCD’s potential to enhance high-fidelity phase detection in ultralow-light scenarios.

Phys. Rev. Applied 21, L061001 (2024) - Published 3 June, 2024

Transportable optical clocks are of great interest for applications in geodesy, because they allow the measurement of geopotential differences with high resolution via their relativistic redshift. So far demonstrations have been limited to short distances or low resolution, but this study presents a measurement between two laboratories separated by several hundred kilometers, with physical height resolution at the decimeter level. The authors compare the result to those obtained with the most accurate established methods in geodesy. Their approach is expected to lead to improved continental and global height reference frames, and connection of tide gauges for sea-level monitoring.

Non-Hermitian unidirectional routing of photonic qubits

En-Ze Li, Yi-Yang Liu, Ming-Xin Dong, Dong-Sheng Ding, and Bao-Sen Shi

Phys. Rev. Applied 21, L061002 (2024) - Published 26 June, 2024

This study employs a non-Hermitian process that effectively balances coherent and dissipative channels, ensuring the unidirectional transfer of photonic qubits. The significance of this approach lies in its applicability to unidirectional routing in both the classical and quantum domains, which is currently challenging to achieve in the synthesis of qubit unidirectional routers and spin-wave diodes. Additionally, this system’s fully optical tunable properties can reverse the direction of qubit transfer. This scheme is expected to greatly impact the design of unidirectional devices in quantum communication and information processing.

Quantum machine learning on near-term quantum devices: Current state of supervised and unsupervised techniques for real-world applications

Yaswitha Gujju, Atsushi Matsuo, and Rudy Raymond

Phys. Rev. Applied 21, 067001 (2024) - Published 4 June, 2024

This Review focuses on the practical implications of quantum machine learning (QML) algorithms and their applicability in real-world domains such as high-energy physics, healthcare, and finance. Despite rising interest in QML, the field contends with numerous challenges, particularly in execution on real quantum devices. This comprehensive exploration of the field delves into those challenges and the proposed solutions to overcome them. The authors provide an extensive survey of different techniques in QML, from data-encoding methods to model types, and offer insight into open questions in the field from a practical standpoint.
