Phys. Rev. Applied 15, L021001 (2021) - Published 5 February, 2021

Mechanical resonators based on silicon nitride membranes offer very high quality factors and outstanding force sensitivity. However, applying such devices as practical sensors has long been impeded by their seemingly incompatible clamping geometry. Using an unconventional setup, the authors realize a membrane-based scanning force microscope and demonstrate nanometer-scale topographic imaging. This instrument is a promising candidate for quantum-limited force detection, and for nuclear spin imaging.

Phys. Rev. Applied 15, 024016 (2021) - Published 5 February, 2021

The entangled optical beams generated by pulsed parametric down-conversion provide enhanced sensitivity for interferometry and enable optical quantum computation, but their rich spatiotemporal modal structure lacks a simple analytic model. This study shows that in properly defined curvilinear coordinates combining the frequency and the transverse wave vector, the modal functions have a simple form and thus can be rather easily analyzed and measured. The authors also show how the degree of spatiotemporal coupling can be manipulated by varying the pump pulse. This approach will have an impact on engineering solutions in quantum optics and computing with highly multimode beams.

Design and Fabrication of Negative-Refractive-Index Metamaterial Unit Cells for Near-Megahertz Enhanced Acoustic Transmission in Biomedical Ultrasound Applications

Jiaying Wang, Florian Allein, Nicholas Boechler, James Friend, and Oscar Vazquez-Mena

Phys. Rev. Applied 15, 024025 (2021) - Published 11 February, 2021

Acoustic metamaterials with negative index of refraction offer great potential for improving resolution and signal transmission in biomedical ultrasound. Their potential has remained unrealized, however, for the lack of a fabrication technology that can create metamaterials compatible with biomedical imaging and operating at frequencies near 1 MHz. The authors report the simulation, fabrication, and characterization of integrated Helmholtz and membrane resonators with characteristic lengths less than 1 mm, produced by silicon-based clean-room microfabrication. Their work finally realizes a negative-index acoustic metamaterial that can be applied in ultrasound imaging and therapeutics.

Phys. Rev. Applied 15, 024027 (2021) - Published 11 February, 2021

Quantum communication is the most advanced cryptographic method to distribute secret keys securely through public channels, but actual performance is still limited, due to noise. This study explores the ultimate noise tolerance of quantum communication by considering a method based on spectral, temporal, and spatial mode filtering of single photons with high efficiency. The authors also show that by actively filtering photons to a nearly single mode, quantum communication can occur in environments that are noisier by three orders of magnitude than what traditional methods tolerate. This approach could bring quantum communication under realistic conditions a step closer to reality.

Stochastic Processes in Magnetization Reversal Involving Domain-Wall Motion in Magnetic Memory Elements

Paul Bouquin, Joo-Von Kim, Olivier Bultynck, Siddharth Rao, Sebastien Couet, Gouri Sankar Kar, and Thibaut Devolder

Phys. Rev. Applied 15, 024037 (2021) - Published 16 February, 2021

Magnetization reversal in nanomagnets is often stochastic at practical temperatures, and this is particularly problematic for information storage, where deterministic switching is sought. Using a combination of experiments, analytical modeling, and numerical simulations, the authors study the physical origin of the stochasticity of domain-wall-based magnetization reversal. Proper choice of nanomagnet geometry renders domain-wall motion largely immune to fluctuations, for almost perfect reproducibility. Combining this with other tricks that make domain-wall nucleation repeatable would minimize write-error rates in memory cells, and thereby allow their further optimization.

Resonant Excitation and Purcell Enhancement of Coherent Nitrogen-Vacancy Centers Coupled to a Fabry-Perot Microcavity

M. Ruf, M.J. Weaver, S.B. van Dam, and R. Hanson

Phys. Rev. Applied 15, 024049 (2021) - Published 19 February, 2021

Quantum networks based on nitrogen-vacancy (N-V) color centers in diamond will enable technology such as communication secured by the laws of nature, and blind quantum computation in the cloud. However, scaling to large distances and many nodes is hindered by the small coherent photon emission and collection from N-V centers. By embedding a thin diamond membrane bearing coherent color centers into an open, tunable fiber-based optical microcavity, the authors demonstrate that the centers’ emission can be enhanced in a fashion compatible with entanglement generation. This work is an important step toward employing N-V centers in large-scale quantum networks with long coherence.

Rocket in your pocket: The creation and laser-driven acceleration of ultrashort electron pulses has drawn much interest in recent years. However, the rather large energy spread of these electron bunches leads to quick decoherence, such that they cannot be trapped in an optical potential well as required. The authors solve this problem using the technique of alternating phase focusing (APF), and experimentally demonstrate attosecond bunching on a chip. This allows scalable acceleration on a microchip without electron losses, and the two-stage nanophotonic APF buncher demonstrated here is the appropriate injector for such an accelerator, as it also provides compatible transverse focusing.

Controlling Microwaves in Non-Hermitian Metamaterials

When designing a metamaterial, to obtain excellent resonance characteristics the dissipative loss of subcomponents usually should be minimized. However, this study takes the opposite approach and harnesses the dissipation. In such a non-Hermitian metamaterial, a bound state in the continuum (BIC) with an infinite Q-factor is observed, and an extremely steep transition from complete extinction to nearly perfect transmission is achieved in a narrow band. By repurposing dissipation as a coupling mechanism, non-Hermitian metamaterials open avenues for microwave sensing, switching, and the realization of slow microwave light.

Phys. Rev. Applied 15, L021004 (2021) - Published 25 February, 2021

Magnetic memories are of great importance for cryogenic platforms that can enable exascale computing, or control of large-scale superconducting quantum processors. Most magnetic memory elements do not perform well at low temperatures, however, and cannot be interfaced directly with superconducting logic schemes. This study demonstrates that spin-orbit-torque devices can be combined with nanoconstriction elements to produce a memory cell that retains the high accuracies and fast switching speeds seen in room-temperature magnetic devices, offering a solution for main memory and cache in high-performance and beyond-Moore computing platforms.
