Efficient and quantum-adaptive machine learning with fermion neural networks

Pei-Lin Zheng, Jia-Bao Wang, and Yi Zhang

Phys. Rev. Applied 20, 044002 (2023) - Published 2 October, 2023

Application of machine learning to quantum data and models has been held back by the lack of adaptability and efficiency in present-day neural networks. This study proposes fermion neural networks for quantum-adaptive machine learning with direct applications to complex quantum systems, and offers in situ analysis without preprocessing or presumption. An efficient optimization comparable to back propagation is established, enabling competitive performance in challenging machine-learning benchmarks. Fermion neural networks’ quantum properties, such as entanglement and correlation, also bring various advantages and insights.

Near-infrared hybrid quantum photonic interface for $^{171} {Yb}^{3 +}$ solid-state qubits

Chun-Ju Wu, Daniel Riedel, Andrei Ruskuc, Ding Zhong, Hyounghan Kwon, and Andrei Faraon

Phys. Rev. Applied 20, 044018 (2023) - Published 6 October, 2023

$^{171}$ Yb $^{3 +}$ ions in yttrium orthovanadate are promising candidates for building quantum networks, based on their excellent optical and spin properties and access to a secondary nuclear-spin quantum register. In this study the authors transfer GaAs photonic crystal nanobeam resonators to the surface of the host YVO $_{4}$ to enhance the optical transitions of the Yb $^{3 +}$ ions and efficiently collect the emitted photons. This hybrid quantum photonic interface facilitates addressing of single Yb $^{3 +}$ ions and paves the way for the implementation of a scalable photonic architecture in the near infrared.

Skyrmions in nanorings: A versatile platform for skyrmionics

Dimitris Kechrakos, Vito Puliafito, Alejandro Riveros, Jiahao Liu, Wanjun Jiang, Mario Carpentieri, Riccardo Tomasello, and Giovanni Finocchio

Phys. Rev. Applied 20, 044039 (2023) - Published 16 October, 2023

After more than a decade of investigation, unconventional Skyrmionics stands as one of the most promising and interesting directions to explore. The authors show the potentials of the combination of skyrmions with nanoring geometry, by proposing three energy-efficient nanoscale devices: A skyrmion clock with a tunable frequency, a skyrmion alternator where the skyrmion motion is converted into an electrical signal (potentially at $μ$ V), and a skyrmion energy harvester to partially recover dissipated heat into electrical energy. This work will stimulate further development in this exciting research direction.

Scalable and programmable three-dimensional photonic processor

Phys. Rev. Applied 20, 044041 (2023) - Published 16 October, 2023

Three-dimensional photonic chips are superior in handling $N P$ -complete problems, but their large-scale application is hindered by the difficulty of programming them. The authors experimentally demonstrate a programmable three-dimensional photonic processor capable of solving the maximum clique problem by encoding injection conditions of photons. The prototype shows the potential of photonic computing, and is applied to solve molecular docking problems. The combination of non-von Neumann parallel computing architectures with fully programmable capabilities paves the way for wider practical applications and photonic computational advantages.

Additive laser excitation of giant nonlinear surface acoustic wave pulses

Jude Deschamps, Yun Kai, Jet Lem, Ievgeniia Chaban, Alexey Lomonosov, Abdelmadjid Anane, Steven E. Kooi, Keith A. Nelson, and Thomas Pezeril

Phys. Rev. Applied 20, 044044 (2023) - Published 17 October, 2023

Pulsed lasers are routinely used to optically excite and detect ultrasounds in a broad frequency range, from megahertz to terahertz. Though well-established for decades, this technique of laser ultrasonics is constrained by the potential optical damage it may cause to the sample, resulting in the generation of relatively weak pressures, well below kilobars. This study introduces a methodology for the excitation of nondestructive shock waves, at a high repetition rate, limited only by the mechanical strength of the sample. This work establishes a way to repeatedly deliver high-amplitude strain pulses to samples of interest, facilitating the dynamical study of strain-induced phenomena.

Gate-voltage switching of nonreciprocal transport in oxide-based Rashba interfaces

Julien Bréhin, Luis M. Vicente Arche, Sara Varotto, Srijani Mallik, Jean-Philippe Attané, Laurent Vila, Agnès Barthélémy, Nicolas Bergeal, and Manuel Bibes

Phys. Rev. Applied 20, 044060 (2023) - Published 24 October, 2023

Rashba interfaces enable spin-charge interconversion via the direct and inverse Edelstein effects, and so may be used to replace ferromagnets as efficient sources and detectors of spin. However, the direction of spins generated by a ferromagnet can be easily switched, while that of spins generated by a Rashba system is usually fixed, being set by its electronic structure. This study shows that in SrTiO $_{3}$ -based Rashba interfaces, where multiple electronic bands contribute differently to charge-spin conversion, the application of gate voltage enables a sign change of the charge-spin conversion effect. This offers possibilities for innovative spin-based logic devices.

Multimode Brownian dynamics of a nanomechanical resonator in a viscous fluid

H. Gress, J. Barbish, C. Yanik, I.I. Kaya, R.T. Erdogan, M.S. Hanay, M. González, O. Svitelskiy, M.R. Paul, and K.L. Ekinci

Phys. Rev. Applied 20, 044061 (2023) - Published 24 October, 2023

The ultimate precision attainable in a mechanical measurement can be determined from the random Brownian motion of the mechanical structure, if the nature of the fluctuations is well understood. To this end, the authors study the Brownian fluctuations of a nanomechanical beam in a viscous fluid. Their predictions based on elasticity theory, fluid dynamics, and statistical mechanics agree well with their experiments, indicating that the observed fluctuations come with “viscous memory”, but no spatial correlations. The insights from this work are expected to impact the design of nanoelectromechanical systems, cantilevers for atomic force microscopy, and other mechanical sensors.
