Heralded single photons are prepared at a rate of approximately 100 kHz via conditional measurements on polarization-nondegenerate biphotons produced in a periodically poled potassium-titanyl phosphate crystal. The single-photon Fock state is characterized using high-frequency pulsed optical homodyne tomography with a fidelity of (57.6+/-0.1)%. The state(More)
We designed novel quantitative real-time polymerase chain reaction (qPCR) primers for the polyphosphate kinase 1 (ppk1) gene, targeting eight individual "Candidatus Accumulibacter" (referred to as Accumulibacter) clades. An evaluation of primer sets was conducted regarding the coverage, specificity, and PCR efficiency. (i) All primer sets were designed to(More)
