Discrimination power of a quantum detector
We investigate the ability of a quantum measurement device to discriminate two states or, generically, two hypotheses. In full generality, the measurement can be performed a number n of times, and arbitrary preprocessing of the states and postprocessing of the obtained data are allowed. There is an intrinsic error associated with the measurement device, which we aim to quantify, that limits its...
متن کاملLow Power and Low Latency Phase-Frequency Detector in Quantum-Dot Cellular Automata Nanotechnology
Nowadays, one of the most important blocks in telecommunication circuits is the frequency synthesizer and the frequency multipliers. Phase-frequency detectors are the inseparable parts of these circuits. In this paper, it has been attempted to design two new structures for phase-frequency detectors in QCA nanotechnology. The proposed structures have the capability of detecting the phase ...
