Abstract

Laser direct write with ultrashort pulses allows high-resolution, high-precision modification inside transparent materials. In diamond, and other wide bandgap semiconductors such as silicon carbide, this provides many opportunities to engineer devices for use in quantum technology. A single ultrashort laser pulse can induce vacancies in the diamond lattice, that may then be mobilized to form stable colour centre defects, which can then be employed as quantum bits. The laser write process can additionally be used to manufacture electrically conductive wires in 3D in the substrate, providing options for control over the qubits.
