SUMMARY:Quantum Nanophotonics Hardware: From Nanofabrication to Quantu
 m Circuit Mapping\, Wisconsin Quantum Institute\, Marina Radulaski\, D

DESCRIPTION:Photonic systems are the leading candidates for determinis
 tic quantum sources\, quantum repeaters\, and other key devices
\nfor 
 quantum information processing. Scalability of this technology depends
  on the stability\, homogeneity and coherence
\nproperties of quantum 
 emitters. Here\, color centers in wide band gap materials offer favora
 ble properties for applications in
\nquantum memories\, single-photon 
 sources\, quantum sensors\, and spin-photon interfaces [1\,2]. Silicon
  carbide\, in particular\,
\nhas been an attractive commercial host of
  color centers featuring fiber-compatible single photon emission\, lon
 g spincoherence
\ntimes and nonlinear optical properties [3]. Integrat
 ion of color centers with nanophotonic devices has been a
\nchallengin
 g task\, but significant progress has been made with demonstrations up
  to 120-fold resonant emission enhancement
\nof emitters embedded in p
 hotonic crystal cavities [4]. A novel direction in overcoming the inte
 gration challenge has been the
\ndevelopment of triangular photonic de
 vices\, recently shown to preserve millisecond-scale spin-coherence in
  silicon carbide
\ndefects [5\,6]. Triangular photonics has promising 
 applications in quantum networks\, integrated quantum circuits\, and
\
 nquantum simulation. Here\, open quantum system modeling provides insi
 ghts into polaritonic physics achievable with realistic
\ndevice param
 eters through evaluation of cavity-protection\, localization and phase
  transition effects [7]. Mapping of this
\ndynamic to gate-based quant
 um circuits opens doors for quantum advantage in understanding cavity 
 quantum
\nelectrodynamical (QED) effects using commercial Noisy Interm
 ediate-Scale Quantum (NISQ) hardware [8].
