Much ado about MOFs: Metal-Organic-Frameworks as Quantum Materials
Metal-organic frameworks (MOFs) are a highly tunable class of crystalline materials where metal atoms or clusters are connected by organic linkers. They offer a versatile platform for exploring quantum phenomena such as entangled magnetism, superconductivity, and topology. Particularly for magnetism, their modular chemistry enables extensive control over magnetic interactions, spin magnitudes, lattice geometries, and even light-responsiveness, making them a uniquely adaptable platform. However,…

Gear-shifting tunable meta-shaft for low-frequency torsional vibration suppression
Metastructures with band gaps provide a new solution for the torsional vibration attenuation in shaft systems, while tunable band gaps remain challenging, typically relying on additional physical fields or complex assembly processes. In this study, a gear-shifting tunable meta-shaft with self-locking gear (SLG) resonators is proposed, where a simple gear-shifting mechanism replaces complex tuning methods to achieve low-frequency torsional vibration suppression in tunable frequency ranges. First…

High-performance multiplexed readout of superconducting qubits with a tunable broadband Purcell filter
Fast, high-fidelity, and low back-action readout plays a crucial role in the advancement of quantum error correction (QEC). Here, we demonstrate high-performance multiplexed readout of superconducting qubits using a tunable broadband Purcell filter, effectively resolving the fundamental trade-off between measurement speed and photon-noise-induced dephasing. By dynamically tuning the filter parameters, we suppress photon-noise-induced dephasing by a factor of 7 in idle status, while enabling rap…

Single layer clathrane: A potential superconducting two-dimensional (2D) hydrogenated metal borocarbide
We propose a new family of two-dimensional (2D) metal-borocarbide clathrane superconductors, derived from three-dimensional (3D) MM$^\prime$B$_6$C$_6$ clathrates. First-principles calculations reveal that hydrogen passivation and surface metal decoration stabilize the M$_2$M$^\prime$B$_8$C$_8$H$_8$ monolayers. These 2D systems exhibit tunable superconductivity governed by hole concentration, structural anisotropy, and electron-phonon coupling. We find that in-plane anisotropy competes with supe…

Voltage-tunable field-free Josephson diode
We report a gate-tunable Josephson diode effect in hybrid nanowire junctions consisting of a spin-orbit-coupled semiconductor core coated with epitaxial ferromagnetic insulator and superconductor shells. The wires display a hysteretic superconducting window as a function of axial magnetic field. In the superconducting regime, the devices exhibit nonreciprocal supercurrent transport, with the diode efficiency showing a strong dependence on back-gate voltage. The effect persists in a remanent mag…

Controlling the recovery time of the superconducting nanowire single-photon detector with a voltage-controlled cryogenic tunable resistor
Superconducting nanowire single-photon detectors (SNSPD), owing to their unique performance, are currently the standard detector in most demanding single-photon experiments. One important metric for any single-photon detector is the deadtime (or recovery time), defined as the minimum temporal separation between consecutive detection events. In SNSPDs, the recovery time is more subtle, as the detection efficiency does not abruptly drop to zero when the temporal separation between detection event…

Fast CZ Gate via Energy-Level Engineering in Superconducting Qubits with a Tunable Coupler
In superconducting quantum circuits, decoherence errors in qubits constitute a critical factor limiting quantum gate performance. To mitigate decoherence-induced gate infidelity, rapid implementation of quantum gates is essential. Here we propose a scheme for rapid controlled-Z (CZ) gate implementation through energy-level engineering, which leverages Rabi oscillations between the |11> state and the superposition state in a tunable-coupler architecture. Numerical simulations achieved a 17 …
