论文摘要
当检测到一个单电子量子回旋子的状态时，可以完全逃避检测器的反作用，但是，它仍然显着扩大了可以推论回旋体频率的量子跳跃共振线路。这限制了可以确定电子磁矩来测试标准模型最精确预测的准确性。一种对主方程的稳态解决方案，是开放量子回旋系统的第一个量子计算，说明了一种在测得的频率下绕过检测背相距的方法。
Detector backaction can be completely evaded when the state of a one-electron quantum cyclotron is detected, but it nonetheless significantly broadens the quantum-jump resonance lineshapes from which the cyclotron frequency can be deduced. This limits the accuracy with which the electron magnetic moment can be determined to test the standard model's most precise prediction. A steady state solution to a master equation, the first quantum calculation for the open quantum cyclotron system, illustrates a method to circumvent the detection backaction upon the measured frequency.
