Rev. Applied 17, 064006 (2022) – Published 2 June 2022 Time-dependent eigenstates of Hamiltonians offer a large degree of tunability, which can be leveraged to operate single- and two-qubit gates so that they stay dynamically protected from noise. However, the usual analytical techniques for describing these gates are limited for systems subject to drives of different frequencies. Thus the authors generalize the Floquet approach to the understanding of such systems, and provide protocols to robustly control and measure these complex systems.

Rev. Applied 17, 064011 (2022) – Published 6 June 2022 For real-world quantum communication, how perfect does a system actually need to be? Here researchers propose a private dense-coding framework using a general preshared quantum state, for quantum secure direct communication that unifies a large number of protocols aimed at secure classical communication using quantum resources. This study provides a detailed performance analysis for the framework in both the asymptotic and nonasymptotic cases, and a better upper bound on information leakage in the finite-length setting. For practical application, the authors also propose an efficient method for implementation, under certain assumptions.

Applied 17, 064025 (2022) – Published 13 June 2022 The rise of artificial intelligence has led to an explosion in demand for computing power—demand that soon will be insatiable using conventional CMOS-based computing hardware. Thus there is a worldwide quest for unconventional hardware that can replace or complement CMOS-based gear. This study contributes to that quest simulations of how reconfigurable logic can be realized in disordered dopant networks in a semiconductor. This paper reveals the operating principles, based on variable-range hopping of charges between randomly located dopants, that underlie the performance of complex classification tasks by these networks.

Wider applicability and the experimental realization of theoretical proposals have been held back due to the relatively large size of such knots. This study shows how to generate optical-vortex knots at the scale of an optical wavelength, which is an important milestone and removes the previous limitations. The authors further observe a change in topology, from a knot to two separated loops.

A widely used charge-sensing technique to extract the tunnel coupling of a double quantum dot accounts for only the ground orbital state in each dot, but the authors show that in a Si double dot, valley-orbit coupling must be included in the analysis. With their more complete model, one can not only extract the i n t r a v a l l e y (ground-state) tunnel coupling more accurately, but also obtain information on i n t e r v a l l e y (ground-to-excited-state) tunnel coupling.

Applied 17, 064057 (2022) – Published 29 June 2022 Artificial spin ices (ASIs) are arrays of Isinglike magnetic nanoislands that are of interest for magnetically reconfigurable computing architectures. Many ASI studies use the metal permalloy, which facilitates geometry-driven studies but leaves material-driven factors largely unexplored. Here the authors study nanoisland magnetic states in ASIs fabricated from the complex oxide La 0 . 7 Sr 0 . 3 MnO 3 (LSMO), and find that both Ising and vortex states can be stabilized through a careful balance of inter- and intraisland energetics enabled by LSMO’s magnetic parameters. These tunable magnetic states provide opportunities to introduce exotic phases into ASI arrays.

Sasaki, Rajesh V. Chopdekar, Scott T. Retterer, Daniel Y. Jiang, Jeremy K. Mason, Michael S. Lee, and Yayoi Takamura Phys. Rev. Applied 17, 064057 (2022) – Published 29 June 2022 Artificial spin ices (ASIs) are arrays of Isinglike magnetic nanoislands that are of interest for magnetically reconfigurable computing architectures. Many ASI studies use the metal permalloy, which facilitates geometry-driven studies but leaves material-driven factors largely unexplored. Here the authors study nanoisland magnetic states in ASIs fabricated from the complex oxide La 0 . 7 Sr 0 . 3 MnO 3 (LSMO), and find that both Ising and vortex states can be stabilized through a careful balance of inter- and intraisland energetics enabled by LSMO’s magnetic parameters. These tunable magnetic states provide opportunities to introduce exotic phases into ASI arrays.

Applied 17, 064060 (2022) – Published 29 June 2022 Metasurfaces could have transformational impact on emerging applications, from smart antennas and 6G communication to the Internet of Things and wireless power transfer, thanks to their ultracompact dimensions and tailored designs. To fully realize this potential, metasurfaces that can implement different functionalities and dynamically switch between them are desired. This study presents a multifunctional microwave metasurface architecture that incorporates electronic components within the unit cell to exert control over the metasurface’s response. Bridging applied physics and device engineering, this work is a concrete step toward readily deployable and versatile metasurface technology.

Applied 17, 064061 (2022) – Published 29 June 2022 Qubit calibration and characterization are important for attaining high-fidelity gates in quantum computing, but require a significant amount of time, which limits a device’s ability to run useful quantum circuits. This study uses r e s t l e s s measurement, in which the qubits are never reset, to speed up characterization and calibration tasks. The authors also show how quantum process tomography may be performed in a restless setting. This approach reduces the footprint of characterization and calibration on quantum processors by quickly and faithfully executing the corresponding circuits. Show Abstract
