UC Santa Barbara Proposes CN Center - Stable Silicon Defect for Quantum Networking

UCSB researchers proposed the CN center silicon defect as a structurally stable telecom-band qubit emitter - solving the fragility problem of T centers caused by hydrogen migration during fabrication. Photonic Inc. is simultaneously exploring deuterium-substituted T centers for improved magnetic field control.

Telecom-band emitters are the foundation of modular quantum architectures that link distributed processors via standard optical fiber.
