The Gertsenshtein effect could in principle be used to detect a single graviton by firing it through a region filled with a constant magnetic field that enables its conversion to a photon, which can be efficiently detected via standard techniques. The quantization of the gravitational field could then be inferred indirectly. We show that for currently available single-photon detector technology, the Gertsenshtein detector is generically inefficient, meaning that the probability of detection is ≪1. The Gertsenshtein detector can become efficient on astrophysical scales for futuristic single-photon detectors sensitive to frequencies in the Hz to kHz range. It is not clear whether such devices are in principle possible.

引力子-光子振荡作为量子引力探针


原则上，Gertsenshtein 效应可用于检测单个引力子，方法是将其发射穿过充满恒定磁场的区域，使其能够转换为光子，这可以通过标准技术有效地检测到。然后可以间接推断引力场的量子化。我们表明，对于目前可用的单光子探测器技术，Gertsenshtein 探测器通常效率低下，这意味着检测概率为 ≪1。Gertsenshtein 探测器可以在天体物理尺度上变得高效，适用于对 Hz 到 kHz 范围内频率敏感的未来主义单光子探测器。目前尚不清楚这种设备原则上是否可行。
