Materials challenges for quantum technologies based on color centers in diamond

Abstract

Emerging quantum technologies require precise control over quantum systems of increasing complexity. Defects in diamond, particularly the negatively charged nitrogen-vacancy (NV) center, are a promising platform with the potential to enable technologies ranging from ultra-sensitive nanoscale quantum sensors, to quantum repeaters for long distance quantum networks, to simulators of complex dynamical processes in many-body quantum systems, to scalable quantum computers. While these advances are due in large part to the distinct material properties of diamond, the uniqueness of this material also presents difficulties, and there is a growing need for novel materials science techniques for characterization, growth, defect control, and fabrication dedicated to realizing quantum applications with diamond.

Two-Dimensional Diamond—Diamane: Current State and Further Prospects

“…105 2D diamane itself, with photon extraction superior to 3D diamond, offers potentially better medium for similar qubit-forming color centers (Figure 3c) for quantum technologies. 106 We believe that this mini review can motivate further research on this nanoscale film class and its particular synthetics route where an active surface chemistry converts a predesigned van der Waals layered precursor into covalently bonded films of targeted properties, contributing to the technological innovation in materials and devices.…”
