Parametric-Resonance Entangling Gates with a Tunable Coupler [PDF]
Physical Review Applied, 2021 High-fidelity parametric gates have been demonstrated with superconducting qubits via rf flux modulation of the qubit frequency. The modulation however leads to renormalization of the bare qubit-qubit coupling, thereby reducing the gate speed.

Floating Tunable Coupler for Scalable Quantum Computing Architectures [PDF]
, 2021 We propose a floating tunable coupler that does not rely on direct qubit-qubit coupling capacitances to achieve the zero-coupling condition. We show that the polarity of the qubit-coupler couplings can be engineered to offset the otherwise constant qubit-

Ultracompact Fiber-to-Chip Metamaterial Edge Coupler
ACS Photonics, 2021 Compact fiber-to-chip light coupling with low loss and large bandwidth, SMF-to-chip edge coupler in particular, is extensively demanded in integrated photonics. The inescapable challenge of edge coupler is the difficulty and complexity in fabrication and

Low-Loss and Broadband Nonvolatile Phase-Change Directional Coupler Switches [PDF]
ACS Photonics, 2018 An optical equivalent of the field-programmable gate array (FPGA) is of great interest to large-scale photonic integrated circuits. Previous programmable photonic devices relying on the weak, volatile thermo-optic or electro-optic effect usually suffer ...

Reconfigurable nanoscale spin-wave directional coupler [PDF]
Science Advances, 2017 We propose a nanoscale spin-wave directional coupler that allows the realization of magnonic integrated circuits. Spin waves, and their quanta magnons, are prospective data carriers in future signal processing systems because Gilbert damping associated ...

A 12.4–32 GHz CMOS Down-Conversion Mixer for 28 GHz 5G New Radio (NR)
Applied Sciences, 2023 We report a low voltage (VDD) and power (PDC) 12.4–32 GHz CMOS down-conversion mixer with high conversion gain (CG) for 28 GHz 5G communications. A quarter-wavelength (λ/4) transmission line (TL) and a coupling capacitor (Cc), named the λ/4-TL-C-based ...

A magnonic directional coupler for integrated magnonic half-adders [PDF]
Nature Electronics, 2019 Magnons, the quanta of spin waves, could be used to encode information in beyond-Moore computing applications, and magnonic device components, including logic gates, transistors and units for non-Boolean computing, have already been developed.
