论文摘要
证明了一个单电子振荡器的阻尼速率的可能性，该电子对于沿着笔陷阱沿磁场轴振荡的电子。可以打开强轴向阻尼，以使该振荡用于量子非隔离检测，对电子的量子和自旋量子状态。可以打开弱轴向阻尼，以避开过去测量值有限的检测运动的背部。新开发的开关将通过两个数量级减少单电子转变的线宽。
The possibility to switch the damping rate for a one-electron oscillator is demonstrated, for an electron that oscillates along the magnetic field axis in a Penning trap. Strong axial damping can be switched on to allow this oscillation to be used for quantum nondemolition detection of the cyclotron and spin quantum state of the electron. Weak axial damping can be switched on to circumvent the backaction of the detection motion that has limited past measurements. The newly developed switch will reduce the linewidth of the cyclotron transition of one-electron by two orders of magnitude.
