The synchronous oscillator (SO) and the coherent phase-locked synchronous oscillator (CPSO) are universal multifunctional networks that track, synchronize, and amplify as much as 80 dB; improve SNR by ...

The phase determines the oscillation frequency, and gain is a criterion for oscillation to exist. The four poles in the loop equation each contribute –45° phase shift accumulating the required total ...

Optical loss degrades quantum correlations, hindering the use of quantum quadrature entanglement for many applications. Researchers have now experimentally demonstrated that this entanglement can be ...

Phase transitions and critical phenomena are the changes of a system from one regime or state to another exhibiting very different properties, and the unusual effects that occur on the boundary ...
