DESCRIPTION:The continued evolution of quantum technologies in diamond requ
 ires heterogenous material platforms for sophisticated functionalities\, d
 evice integration and packaging\, and improved qubit performance. At UChic
 ago and Argonne National Laboratory\, we are creating pristine single-crys
 tal diamond membranes that host coherent color center qubits and integrati
 ng them with a wide range of materials including fused silica\, sapphire\,
  thermal oxide\, lithium niobate\, tantalum\, silicon and YIG. The membran
 e uniformity and robustness to fabrication enables several varieties of in
 tegrated nanophotonic cavities – critical elements in quantum photonics 
 - with record quality factors. Furthermore\, we show that our ultra-thin d
 iamond membranes are compatible with total internal reflection fluorescenc
 e (TIRF) microscopy\, which enables interfacing coherent diamond quantum s
 ensors with living cells while rejecting unwanted background luminescence.
  Remarkably\, we demonstrate that membrane integration can improve the spi
 n coherence and microwave addressability of tin vacancy qubits while maint
 aining exceptional optical coherence\, allowing us to create an operationa
 l spin-photon interface at 4 Kelvin. In total\, the combination of qubit p
 erformance\, high-performance device fabrication\, and flexible materials 
 integration will enable a broad range of quantum photonic\, acoustic\, and
  sensing science and technologies. We will also demonstrate that color cen
 ters can function as optical antennas that can efficiently concentrate opt
 ical energy in solids\, with up to million-fold local intensity enhancemen
 t under resonant excitation\, and discuss potential applications in spectr
 oscopy\, sensing\, and quantum science.
