We discuss our experimental exploration of how spontaneous photonic crystals form supported by polarization supercrystals (PSCs) in near-transition potassium-lithium-tantalate-niobate (KTN:Li) and its implications for topologically-protected photonic waveguides and memory bits.
In Linear Optics Quantum Computing, the research aims to optimize a Silicon Photonic Integrated Circuit, focusing on the universal two-qubit Controlled-NOT gate prototype, which operates on a linear, coincidence basis with single-photon inputs.
