We present a 10 GHz dual loop optoelectronic oscillator (OEO), with very low phase noise (−144.7 dBc/Hz at 10 kHz) and low spur level (−145 dBc/Hz), despite using short fibers (1 km/100 m). The OEO is ...

We significantly strengthen and generalize the theorem lifting Nullstellensatz degree to monotone span program size by Pitassi and Robere (2018) so that it works for any gadget with high enough rank, ...
