Quantum information technology offers the potential to realize unprecedented computational resources via secure channels distributing entanglement between quantum computers. Diamond, as a host optically-accessible spin qubits, is leading platform memory nodes needed extend such links. Photonic crystal (PhC) cavities enhance light-matter interaction and are essential for an efficient interface spins photons that used store communicate respectively. Here, we demonstrate one- two-dimensional...
The T center in silicon has recently emerged as a promising candidate for scalable quantum technologies, due to its telecommunications band optical transition and microwave addressable ground state spin. immense promise of the is driven by host material; far most mature, manufacturable semiconductor material integrated photonic electronic devices.

Systems of spins engineered with tunable density and reduced dimensionality enable a number advancements in quantum sensing simulation. Defects diamond, such as nitrogen-vacancy (NV) centers substitutional nitrogen (P1 centers), are particularly promising solid-state platforms to explore. However, the ability controllably create coherent, two-dimensional spin systems characterize their properties, density, depth confinement, coherence is an outstanding materials challenge. We present refined...
Color centers have emerged as a leading qubit candidate for realizing hybrid spin-photon quantum information technology. One major limitation of the platform, however, is that characteristics individual color are often strain dependent. As an illustrative case, silicon-vacancy center in diamond typically requires millikelvin temperatures order to achieve long coherence properties, but strained been shown operate at beyond 1 K without phonon-mediated decoherence. In this work, we combine...
