Phys. Rev. Applied 20, 034001 (2023) - Published 1 September, 2023

Hot-carrier solar cells (HCSCs) are one option for achieving solar-energy conversion more efficiently than conventional single-junction cells. Due to challenging material requirements, the development of HCSCs has been limited to proof-of-concept devices. By examining heat flow in HCSCs, this study suggests expanding their characterization to include the study of carrier temperatures for various contact configurations and biases. The authors show that hotter is not always better: High carrier temperatures may be a sign of excessively high barriers to extraction—an insight that could adjust expectations and interpretations of hot-carrier temperatures in devices.

Ultrashort Electron Wave Packets via Frequency-Comb Synthesis

Matteo Aluffi, Thomas Vasselon, Seddik Ouacel, Hermann Edlbauer, Clément Geffroy, Preden Roulleau, D. Christian Glattli, Giorgos Georgiou, and Christopher Bäuerle

Phys. Rev. Applied 20, 034005 (2023) - Published 5 September, 2023

Single-electron sources are vital for modern nanoelectronics, enabling advances in the emerging field of electron quantum optics. However, their performance is limited by the current method for generating single electrons by applying Lorentzian voltage pulses on the Fermi sea of a quantum conductor. The authors introduce a Fourier synthesis-based voltage pulse generator, allowing the generation and in-situ characterization of a 27-ps electron wave packet in an electronic Mach-Zehnder interferometer. This advancement can potentially enable the study of ultrafast dynamics in quantum nanoelectronic systems and the generation of high-frequency flying-electron qubits.

Phys. Rev. Applied 20, 034006 (2023) - Published 6 September, 2023

The efficiency of spin-transfer-torque magnetic random-access memory (MRAM) critically depends on the damping of the free layer. As MRAM cells operate above room temperature, it is crucial to determine the damping parameter of the free layer at elevated temperatures. This study uses ferromagnetic resonance techniques to measure the damping of MRAM free layers up to 520 K. The data show significant differences in temperature dependence between conventional and low-damping free-layer designs, paving the way for MRAM cells with lower switching current. These insights could impact the development of more efficient and thermally stable MRAM technologies.

Acoustically Induced Spin Resonances of Silicon-Vacancy Centers in $4 H$ -SiC

T. Vasselon, A. Hernández-Mínguez, M. Hollenbach, G.V. Astakhov, and P.V. Santos

Phys. Rev. Applied 20, 034017 (2023) - Published 11 September, 2023

Silicon vacancies in 4 $H$ -SiC are color centers with promising applications in quantum technologies, but spin control of the centers generated in a hexagonal local crystallographic environment has yet to be demonstrated above cryogenic temperatures. The authors use the dynamic strain of surface acoustic waves to overcome this limitation and efficiently excite spin transitions in the excited states of these color centers up to room temperature. The acoustic spin control of silicon vacancies opens possibilities for the implementation of efficient quantum spin control and sensing protocols using spin optomechanics.

Long-Lived Singlet State in an Oriented Phase and its Survival across the Phase Transition Into an Isotropic Phase

Vishal Varma and T.S. Mahesh

Phys. Rev. Applied 20, 034030 (2023) - Published 14 September, 2023

Long-lived states (LLSs) in nuclear magnetic resonance have diverse applications, from medical imaging to chemical analysis to quantum information processing, but were hitherto observed primarily in isotropic phases. The authors prepare LLS in an anisotropic environment of a liquid crystal and observe its survival across the phase transition to the isotropic phase. This study could pave the way for trapping LLS in the symmetric spin pair of an isotropic phase after breaking symmetry in an anisotropic phase, and motivate the realization of LLS in the solid phase, which will have implications for solid-state qubits toward achieving longer lifetimes in addition to long-range interactions.

Semiconductor-Quantum-Dot Modulator for Cryogenic Operation of Quantum Circuitry

M. R. Hogg, M.G. House, P. Pakkiam, and M.Y. Simmons

Phys. Rev. Applied 20, 034066 (2023) - Published 27 September, 2023

Quantum computing devices have the potential to solve problems that are beyond even the most powerful modern supercomputers. Most quantum hardware operates at temperatures near absolute zero, but controlling a quantum computer at cryogenic temperatures using signals propagating from room temperature becomes infeasible for large-scale processors. The authors explore a device that allows control signals to be generated on-chip at cryogenic temperatures, potentially mitigating this cryogenic bottleneck. Their device is fabricated in silicon using established technologies for quantum processors, providing a pathway towards a hybrid quantum-classical integrated circuit.

Tuning Arrays with Rays: Physics-Informed Tuning of Quantum Dot Charge States

Joshua Ziegler, Florian Luthi, Mick Ramsey, Felix Borjans, Guoji Zheng, and Justyna P. Zwolak

Phys. Rev. Applied 20, 034067 (2023) - Published 28 September, 2023

Many methods to automatically tune silicon spin qubits are limited by reliability and data efficiency, which makes them less likely to be scalable. The authors demonstrate a reliable, efficient, physics-informed tuning algorithm (PIT) for navigating to a target charge configuration⏤a prerequisite to forming qubits. This tuning method combines machine learning and physical intuition with an algorithm that leverages one-dimensional scans (rays) and conventional peak-finding to navigate from a coarse, unknown device state to a desired charge occupation efficiently and effectively. PIT enables the transformation of an uncalibrated circuit to a functioning quantum processor.

Highly Sensitive Temperature Sensing Using the Silicon Vacancy in Silicon Carbide by Simultaneously Resonated Optically Detected Magnetic Resonance

Yuichi Yamazaki, Yuta Masuyama, Kazutoshi Kojima, and Takeshi Ohshima

Phys. Rev. Applied 20, L031001 (2023) - Published 5 September, 2023

Quantum sensors based on silicon vacancies ( $V_{Si}$ ) in SiC are crucial for precise device design and simulations, but their practical application is hampered by the low sensitivity of temperature. This study introduces a temperature measurement protocol that increases signal intensity by an order of magnitude. By diverting part of the ground state optically detected magnetic resonance signal for temperature measurement, and leveraging simultaneous resonance of the ground state and excited state, the protocol significantly boosts performance. This leap in measurement sensitivity could make $V_{Si}$ -based quantum sensors far more effective and versatile.

Quantum computing devices have the potential to solve problems that are beyond even the most powerful modern supercomputers. Most quantum hardware operates at temperatures near absolute zero, but controlling a quantum computer at cryogenic temperatures using signals propagating from room temperature becomes infeasible for large-scale processors. The authors explore a device that allows control signals to be generated on-chip at cryogenic temperatures, potentially mitigating this cryogenic bottleneck. Their device is fabricated in silicon using established technologies for quantum processors, providing a pathway towards a hybrid quantum-classical integrated circuit.

Many methods to automatically tune silicon spin qubits are limited by reliability and data efficiency, which makes them less likely to be scalable. The authors demonstrate a reliable, efficient, physics-informed tuning algorithm (PIT) for navigating to a target charge configuration⏤a prerequisite to forming qubits. This tuning method combines machine learning and physical intuition with an algorithm that leverages one-dimensional scans (rays) and conventional peak-finding to navigate from a coarse, unknown device state to a desired charge occupation efficiently and effectively. PIT enables the transformation of an uncalibrated circuit to a functioning quantum processor.

Phys. Rev. Applied 20, 037001 (2023) - Published 18 September, 2023

Technological progress in optical communication and signal-processing systems looks to ultrafast optical switches and modulators, and to ultrafast electron sources for imaging. This review discusses how to use surface plasmons to advance miniaturization and reduce energy consumption. Obstacles here include integrating such devices with conventional techniques, and the diffraction limit preventing the realization of subwavelength scale. In particular, the authors offer insight on the development trends and design of such ultrafast devices, in terms of the various advantages of surface plasmons in different nanostructures and materials.
