Telewave cavities do support the dynamic change of the "Q" of a cavity by adjusting the angle of the loop (s) in relation to the inner conductor. Turning the loop (s) to add insertion loss increases the "Q", decreasing the insertion loss decreases "Q". The pass or reject band symmetry can also be changed by adjusting the loop angles ...

Abstract. Cavity-assisted quantum memory storage has been proposed for creating efficient (close to unity) quantum memories using weakly absorbing materials. Using this approach, we experimentally demonstrate a significant (∼20-fold) enhancement in quantum memory efficiency compared to the no cavity case.

The energy storage rate is accelerated and stored heat power is also increased by mounting cavity partitions and fins, though the storage capacity is not changed much. Compared to the baseline case without partitions and fins, the power could be increased by 117.5 %–242.6 % and 128.1 %–348.5 % with 4 fins and 8 fins, respectively.
