In superconducting circuits, are employed to suppress charge fluctuations and increase zero-point voltage, enabling features for hardware-protected qubits, metrological standards, and strongly coupled hybrid devices. Conventionally these devices are based on kinetic inductance, and can suffer from nonlinearity, additional complexity due to multiterminal structure, and the limited control and reliability of bottom-up fabrication. Making use of miniaturization and substrate engineering, the authors realize a geometrically defined, single-wavefunction superinductor—a high-performance, innovative circuit element that promises to expand the scope of quantum circuitry.

Acoustic metasurfaces offer remarkable control of wave transmission and reflection, but with limited power efficiency in traditional systems. Perfect wavefront transformation with perfect efficiency traditionally requires either nonreciprocal or nonlocal responses, which are challenging to implement with passive designs. This study uses the automatically excited surface waves to design impedance-based acoustic metasurfaces requiring only reciprocal and local responses; thus passive structures suffice. Counterintuitively, transmission-type metasurfaces require nonzero reflected fields for maximum efficiency, and reflection-type metasurfaces need nonzero transmitted fields.

Detecting the presence of photons in a propagating microwave mode has been demonstrated only recently, and an important tool still missing is a photocounter able to determine in a single shot the number of photons in an incoming mode. The authors create such a photocounter by catching an incoming wave packet in a stationary mode, and then measuring the photon number of that mode bit by bit, using an ancillary qubit. Additionally, this device can measure the envelope of the incoming wave packet . Beyond its direct applications in quantum sensing, this photocounter allows development of quantum information protocols that benefit from real-time feedback based on photon number.

One of the major challenges in building fully functional quantum computers based on superconducting circuits is a scalable, high-fidelity two-qubit gate. Microwave-induced gates are appealing, but so far have been restricted to small qubit detunings, leading to frequency crowding and reduced gate speed and qubit addressability, due to crosstalk. The authors present a high-fidelity all-microwave gate based on a Raman transition, which allows for detunings that are large compared to the anharmonicity of the qubits, setting the stage for scalable, resource-efficient quantum processors.

is a simple yet powerful means to stabilize and control laser oscillators, with many applications, but in the context of integrated photonics the technique has remained relatively unexplored. Here researchers demonstrate injection locking in a chip-integrated, all-silicon laser oscillator, and use this approach to achieve more than 23 dB of Brillouin-based on-chip amplification. Due to the phase-matched properties of the stimulated intermodal Brillouin process, this form of control is intrinsically , meaning that the laser oscillator is naturally impervious to unwanted backscattering.

Through the bulk photovoltaic effect (BPVE), devices based on ferroelectric (FE) perovskite oxides can overcome the Shockley-Queisser efficiency limit for solar cells. For efficient visible-light absorption, these oxides require the usually contradictory properties of small band gap and a transition metal at the site in their O structure. Here both first-principles calculations and experiment are used to study the cosubstitution of Mo and Ti for Nb in KNbO. This substitution yields a band gap of 2.2 eV while preserving the FE polarization. The obtained solid solution is a promising absorber material for photovoltaic applications exploiting the BPVE.
