Quantization of Mechanical Motion
... A measurement affects the quantum state by transforming it into another state with a definite value of the measured variable. The corresponding transformation of the wave function can be viewed as the action of some operator. This is the reason to attribute to any physical variable an operator of th ...

... In Bob’s site, the 1 GHz pulse stream is input to a PLC-MZI. Two pairs of SSPDs [20] (Det1 and Det2, Det3 and Det4) are connected to each of the output ports of Mach-Zehnder interferometer with a 50:50 coupler. The detected signals are input into a time interval analyzer (TIA) via a logic gate to re ...
