Fabricating electronics from solid-state quantum emitters is a promising strategy for the miniaturization and integration of electronic devices. However, the practical realization of solid-state quantum devices and circuits for signal transmission and processing at room temperature has remained challenging. Herein, we investigated the multi-bunching phenomenon by generating multi-order fluorescence from a pseudo-thermal source at room temperature using the nitrogen-vacancy (NV) center in diamond. We demonstrate the shift in time of multi-bunching by controlling the effect of dressing to realize logical gates and transistor switching operations. We also suggest the optimization of the time propagation delay (TPD) of the gate circuit by changing the boxcar gate position.
In this paper, we study the realization of a multi-contact switch using the double-dressing regularity of probe, fluorescence, and six-wave mixing signals in a five-level Rb atomic system. For the first time, we compare the dressing regularity of Rydberg states by observing electromagnetically induced transparency and signals. With the scanning probe and dressing fields, both large and small line shifts in signals are observed. The small line shifts are induced by double-dressed line shifts. Also, the big line shifts result from the Rydberg dressing. In addition, with an increase in the principal quantum number of the Rydberg state, all the signals become weaker, while the line shifts of the signals become enhanced. Using the regularity in line shifts of the signals and an acoustic optical modulator to modulate the frequency detuning, we can realize a multi-contact switch action and fast conversion between different contacts.
