Quasiparticle Dynamics in a Superconducting Qubit Irradiated by a Localized Infrared Source.

A known source of decoherence in superconducting qubits is the presence of broken Cooper pairs, or quasiparticles. These can be generated by high-energy radiation, either present in the environment or purposefully introduced, as in the case of some hybrid quantum devices. Here, we systematically study the properties of a transmon qubit under illumination by focused infrared radiation with various powers, durations, and spatial locations.

Hybrid Integration of Silicon Photonic Devices on Lithium Niobate for Optomechanical Wavelength Conversion.

The rapid development of quantum information processors has accelerated the demand for technologies that enable quantum networking. One promising approach uses mechanical resonators as an intermediary between microwave and optical fields. Signals from a superconducting, topological, or spin qubit processor can then be converted coherently to optical states at telecom wavelengths.

Reconstructive plastic surgery in hemophiliacs.

Major surgery can be safely performed in hemophiliacs when adequate factor activity is provided, i.e., 100 percent activity perioperatively and 50 percent activity thereafter.

The vastus lateralis myocutaneous flap.

Four case reports of decubiti treated with vastus lateralis myocutaneous flaps are presented. The operative technique is described in detail. This method, closing the donor site primarily over Hemovac drains and eliminating the use of skin grafts, can be used to cover defects in a variety of locations.
