New thin-film diamond photonic crystal platform achieved record quality factors up to 1.8x10^5
Realized high-performance photonic crystal cavities challenging to fabricate previously
Demonstrated efficient coupling between silicon vacancy qubit and photonic crystal cavity
New platform based on planar fabrication is higher yield and expands quantum diamond capabilities
Photonic crystals serve as efficient interfaces between spin qubits and photons for networking
Efficient diamond photonic crystal platform enables high-performance quantum interfaces
Researchers developed a new fabrication approach for diamond photonic crystals that achieved record-high quality factors, using a thin-film diamond platform. This enables more efficient spin-photon interfaces critical for quantum technologies. The new platform simplifies fabrication and expands design flexibility compared to previous diamond undercut etching approaches.
