Spintronic terahertz emitters (STEs) are desirable broadband terahertz sources, but their limited signal strength has hindered practical application. By optimizing the photonic and thermal environment, the authors present an STE that could overcome this obstacle. Benchmarking against the state-of-the-art terahertz emitters based on optical rectification, this STE delivers strong terahertz pulses with comparable peak electric field and fluence, and offers additional features such as broadband radiation, easy alignment, and rotation of the terahertz polarization plane without power loss. This work will open up a promising pathway to nonlinear terahertz spectroscopy with spintronic sources.

Phys. Rev. Applied 19, 034023 (2023) – Published 8 March 2023

One of the world’s tiniest autonomous refrigerators can be realized by a single qutrit coupled to three thermal reservoirs. The authors analyze the performance of multiple collectively coupled qutrits, and observe a quantum boost in the steady-state cooling current with a quadratic scaling in the working fluid size. With additional interqutrit interactions, the quantum boost can be maintained also for larger systems and not perfectly collective scenarios, enabling efficient quantum cooling.

A distributed quantum network requires versatile and high-fidelity quantum memory nodes, but it remains challenging to make them scalable. This study investigates the use of multiple controllable quantum memories in silicon carbide—an established semiconductor material platform for various quantum technology applications—and provides a viable solution. The authors show that solid-state spins in silicon carbide are ideal quantum memories in a distributed quantum computing network, wherein a controlled generation of highly coherent qubit registers using nuclear spins is possible. This study will impact the future development of quantum networks with solid states spins as quantum memories.

Time-dependent external flux is ubiquitous across circuit quantum electrodynamics and calls for accurate modeling. Contrary to long-held belief, it is recently predicted—but not yet verified—that the allocation of time-dependent flux cannot be arbitrary in the Hamiltonian. This study provides an experimental verification of this prediction by applying fast flux pulses to a fluxonium qubit and taking measurements of the quantum state following the pulses. Given the widespread use of time-dependent flux in experiments with superconducting qubits, verification of this theory is critical to our understanding of circuit quantum electrodynamics.

Electron-beam sources are foundational in high-resolution electron microscopy and spectroscopy, but applications have been limited due to their relatively large energy spread. The authors fabricate a monocrystalline niobium nanotip electron field emitter and characterize it in superconducting and normal-conducting regimes. This bright, stable, coherent electron beam source features an exceptionally narrow energy spread. The authors also study the role of xenon adsorption and two-electron correlations. This work may improve aberration-corrected microscopy and electron energy-loss spectroscopy and enable high-resolution vibrational spectroscopy or quantum electron microscopy.

Phys. Rev. Applied 19, 034064 (2023) – Published 20 March 2023

To better understand decoherence in superconducting qubits, the authors develop a technique to measure the loss tangent of dielectric substrates and predict the impact of dielectric loss on qubit lifetimes. This is done with no need to fabricate planar devices; the technique is independent of material platform. Measurements of sapphire in a demonstration of the approach suggest that coherence of superconducting qubits on a common form of sapphire is limited significantly by bulk dielectric loss. The same technique also shows that another form of sapphire would substantially mitigate this bulk dielectric loss and prolong qubit coherence.

Here researchers investigate how well a coherent Ising machine (CIM), based on a network of degenerate optical parametric oscillators, simulates the thermodynamic properties of a two-dimensional square-lattice Ising model. Assuming that the CIM samples can be regarded as a canonical ensemble, the authors estimate the effective temperature of spins (optical pulses) using maximum-likelihood estimation. Using that temperature, the thermodynamic quantities obtained from the CIM exhibit phase-transition-like behavior that matches analytical and numerical results better than what the mean-field approximation produces. This result shows the promise of physical thermodynamics simulators.

Nonlinear parametric processes in optical fibers provide opportunities to expand advanced fiber-based technologies of lasers, communications, and sensors, but their efficiencies are significantly degraded by phase mismatching. This study proposes a strategy to accurately control the phase matching of optical harmonic generations in a microfiber, by applying a mechanical strain that modifies its structure and refractive index. This effective strategy to optimize nonlinear processes will be beneficial to all-fiber nonlinear optics and could extend their applications in optical communications and signal processing.

The ultrahigh-frequency magnetization dynamics of antiferromagnets and ferrimagnets is a key property that could be exploited for terahertz technology and spintronics. Despite recent advances in measuring bulk samples, no techniques have been available to characterize such fast dynamics in the thin films that are important for devices. In this Letter the authors use a gyrotron to demonstrate electrical detection of subterahertz magnetization dynamics in thin films, revealing peculiar antiferromagnetic behavior in Gd-Co.

The detection of fluctuating electromagnetic fields through single-spin relaxometry affords important insight into the dynamics of solid-state systems and chemical processes, but its sensitivity is often limited by the proximity of the sensor spin to the target. This study proposes the use of an auxiliary reporter spin to improve sensitivity by as much as a factor of 100, and experimentally verifies the method with a single shallow nitrogen-vacancy center in diamond. This work motivates the development of engineered spin systems as relaxation sensors without the need for optical initialization or readout.

Tomorrow’s quantum Internet will be powered by light and will work over today’s telecommunication infrastructure, so we need low-noise, high-bandwidth, telecom-band quantum optical memory to enable scaling in the presence of loss and quantum operations. The authors have built such a device, using coherent two-photon absorption in warm rubidium vapor. This quantum memory stores gigahertz-bandwidth telecom-band light pulses with mean photon number less than one, and retrieves them with a signal-to-noise ratio exceeding 10

Understanding the Quality Factor of Mass-Loaded Tensioned Resonators
R. Shaniv, S. Kumar Keshava, C. Reetz, and C.A. Regal
Phys. Rev. Applied 19, L031006 (2023) – Published 29 March 2023

Mass-loaded tensioned microresonators are important in mass-dependent applications like inertial sensing and fundamental research in e.g. quantum gravity, as they combine superb displacement detection with low mechanical dissipation. However, loading a resonator often changes its mode structure and enhances its mechanical loss. The authors study the effect of loading on mode quality factor, varying the load from much smaller to larger than the resonator’s total mass. Surprisingly, the quality factor becomes independent of the mass in the large-load regime, which explains previous related results and provides fresh perspective for design.

To better understand decoherence in superconducting qubits, the authors develop a technique to measure the loss tangent of dielectric substrates and predict the impact of dielectric loss on qubit lifetimes. This is done with no need to fabricate planar devices; the technique is independent of material platform. Measurements of sapphire in a demonstration of the approach suggest that coherence of superconducting qubits on a common form of sapphire is limited significantly by bulk dielectric loss. The same technique also shows that another form of sapphire would substantially mitigate this bulk dielectric loss and prolong qubit coherence.

Phys. Rev. Applied 19, 037001 (2023) – Published 22 March 2023

The familiar work function 
Φ
 (the energy barrier for an electron to move across a material’s surface into the vacuum) is central to a vast array of surface and interfacial processes, and thus is fundamental to technologies ranging from vacuum and solid-state electronics to catalysis. Despite this importance, multiple issues associated with the varying vacuum level of electrons near surfaces often obscure how 
Φ
 is being defined, measured, and used. This Review clarifies the definition of 
Φ
 with extra care, summarizes recent approaches for calculating and predicting 
Φ
, and discusses how tuning bulk electronic structure and surface dipoles can be used to engineer 
Φ
.

Near-Field Thermophotovoltaic Energy Conversion: Progress and Opportunities
Rohith Mittapally, Ayan Majumder, Pramod Reddy, and Edgar Meyhofer
Phys. Rev. Applied 19, 037002 (2023) – Published 29 March 2023

Thermophotovoltaic (TPV) energy conversion is a promising power-generation technology for converting heat to electricity. Recent studies have explored TPV devices featuring nanoscale gaps, which take advantage of near-field effects that enable much larger radiative fluxes and power density. The authors review the physics of near-field thermal radiation, and assess theoretical and experimental advances in predicting and validating near-field enhancements of power output and efficiency in TPV devices. Their discussion of the near-field photonic heat engines presented here will help to guide future engineering solutions in developing practical near-field energy-conversion devices.
