Real-Time Charge Initialization of Diamond Nitrogen-Vacancy Centers for Enhanced Spin Readout
David A. Hopper, Joseph D. Lauigan, Tzu-Yung Huang, and Lee C. Bassett
Phys. Rev. Applied 13, 024016 (2020) – Published 7 February 2020

Spin qubits based on nitrogen-vacancy centers in diamond are useful only when the defect exists in the correct charge state—but this state is usually uncontrolled, since it is sensitive to the optical fields used to interrogate the qubit. Using fast, real-time photon detection and control, the authors deterministically prepare the desired charge state and demonstrate that the qubit’s performance as a magnetic sensor is dramatically improved. These experiments yield deeper understanding of the charge and spin dynamics of N-V centers, and the all-optical method can be adapted to dynamically control other stochastic properties of solid-state defects for improved performance.

Phase-Modulated Entangling Gates Robust to Static and Time-Varying Errors
Alistair R. Milne, Claire L. Edmunds, Cornelius Hempel, Federico Roy, Sandeep Mavadia, and Michael J. Biercuk
Phys. Rev. Applied 13, 024022 (2020) – Published 11 February 2020

In quantum computing systems where entangling logic gates are mediated via bosonic oscillator modes (e.g. trapped ions), residual coupling between qubits and oscillator is a dominant source of gate infidelity. This work shows how discrete phase modulation of the field mediating the entangling operation ensures that the system of qubits is decoupled from multiple oscillator modes, even in the presence of common time-varying sources of noise and hardware instability. The results demonstrate the capabilities of quantum control to drive major performance advances in quantum computing.

Linear and Nonlinear Elastic Waves in Magnetogranular Chains
F. Allein, V. Tournat, V. Gusev, and G. Theocharis
Phys. Rev. Applied 13, 024023 (2020) – Published 11 February 2020

Granular phononic crystals have become an appealing platform for the study of a plethora of nonlinear wave phenomena in mechanical structures, and for applications such as vibration filters, tunable switches, and rectifiers. Here the authors reveal the strong benefit of using external magnetic fields to design mechanically unconstrained granular crystals. The resulting magnetogranular crystals are used for a detailed study of both longitudinal and transverse-rotational nonlinear waves. This system offers great freedom in designing complex waveguide geometries, where the interplay between geometry, wave polarization, and nonlinearity could be harnessed for advanced signal processing.

Multimode Time-Delay Interferometer for Free-Space Quantum Communication
Clinton Cahall, Nurul T. Islam, Daniel J. Gauthier, and Jungsang Kim
Phys. Rev. Applied 13, 024047 (2020) – Published 19 February 2020

Optical communication via free-space channels is attractive for establishing long-range secure quantum networks, but is often hindered by deleterious effects on the transverse spatial mode profile of the beam, caused by propagation through the atmosphere. Additionally, interferometric measurement at the receiver becomes much more difficult with multimode profiles. This study presents a compact time-delay interferometer with high stability and interference visibility for single- and multimode spatial profiles. The results of this study are important for the future of quantum communication networks as well as a wide range of techniques for classical and quantum optical measurement.

Edge-Plasmon Whispering-Gallery Modes in Nanoholes
M. Lorente-Crespo, G.C. Ballesteros, C. Mateo-Segura, and C. García-Meca
Phys. Rev. Applied 13, 024050 (2020) – Published 20 February 2020

Metallic apertures support a rich variety of widely investigated electromagnetic phenomena, which are the basis of many optical devices. Research on edge plasmons in these structures is scarce, though, and limited to dipolar resonances. This study shows that nanoholes additionally support high-order edge plasmons, in the form of whispering-gallery modes. Notably, the excited orders are determined by the lattice symmetries, are very sensitive to the environment, and exhibit highly tailorable features. These results shed light on the physics of metallic nanoholes and point to applications in nanophotonics and plasmonics.

Scanning Tunneling Thermometry
Abhay Shastry, Sosuke Inui, and Charles A. Stafford
Phys. Rev. Applied 13, 024065 (2020) – Published 25 February 2020

With scanning-probe techniques now widespread, many physical properties can be imaged with atomic precision, providing insight into the quantum world. However, temperature so far has proven impossible to measure with subnanometer resolution. The key hurdle in high-resolution thermal images is reliance on a heat-flux-related signal, which inevitably results in a tradeoff between signal strength and image resolution. The authors propose instead to infer the local temperature of a conducting surface based purely on electrical (not heat-flux) measurements, which may be carried out in the tunneling regime. This would seem to open a vista onto the world of quantum thermodynamics.

Experimental Observation of Nonreciprocal Waves in a Resonant Metamaterial Beam
M.A. Attarzadeh, J. Callanan, and M. Nouh
Phys. Rev. Applied 13, 021001 (2020) – Published 14 February 2020

Structures hosting nonreciprocal (one-way) wave propagation are of key interest in signal processing, sensing, and civil infrastructure, yet experimental realization has so far relied on adaptive materials and external stimulation, which require significant power and are not scalable beyond lab prototypes. This work presents an elastic metamaterial that exploits stiffness variations in an array of geometrically phase-shifted resonators to achieve a nonreciprocal tilt of dispersion modes within dynamic modulation regimes. The ability to induce asymmetric vibrational modes in a scalable, energy-efficient manner has direct implications for numerous applications.

Huygens Metasurfaces Based on Congener Dipole Excitations
Tianhua Feng, Alexander A. Potapov, Zixian Liang, and Yi Xu
Phys. Rev. Applied 13, 021002 (2020) – Published 18 February 2020

Metasurfaces are powerful platforms for controlling light, with bandwidth and efficiency being the two key parameters. Here conventional transmissive metasurfaces suffer, because they rely on multipoles of different resonant nature to construct Huygens sources. The authors explore the possibility of utilizing congener dipoles (solely electric, without a magnetic component) with similar resonant properties to release these constraints. Beam deflection and focusing, over a broad wavelength band and with high efficiency, are demonstrated. This approach extends the design methodology and improves the performance of metasurfaces.

Editing Arbitrarily Linear Polarizations Using Programmable Metasurface
Qian Ma, Qiao Ru Hong, Guo Dong Bai, Hong Bo Jing, Rui Yuan Wu, Lei Bao, Qiang Cheng, and Tie Jun Cui
Phys. Rev. Applied 13, 021003 (2020) – Published 28 February 2020

Manipulating the polarization of electromagnetic waves is an important topic in metamaterial research, but conventional methods for tailoring polarization are usually passive or function-limited. To address this issue, the authors create reprogrammable polarization states with a digital coding metasurface to achieve diverse polarization modulations. By applying distinct digital coding sequences, the polarization angle of the reflected beam can be modulated as desired. This flexible, efficient approach will promote applications in communication and imaging, and will increase the potential for information processing with metamaterials.

Scanning Tunneling Thermometry

With scanning-probe techniques now widespread, many physical properties can be imaged with atomic precision, providing insight into the quantum world. However, temperature so far has proven impossible to measure with subnanometer resolution. The key hurdle in high-resolution thermal images is reliance on a heat-flux-related signal, which inevitably results in a tradeoff between signal strength and image resolution. The authors propose instead to infer the local temperature of a conducting surface based purely on electrical (not heat-flux) measurements, which may be carried out in the tunneling regime. This would seem to open a vista onto the world of quantum thermodynamics.
