Circumventing Detector Backaction on a Quantum Cyclotron
نویسندگان
چکیده
Detector backaction can be completely evaded when the state of a one-electron quantum cyclotron is detected, but it nonetheless significantly broadens quantum-jump resonance lineshapes from which frequency deduced. This limits accuracy with electron magnetic moment determined to test standard model's most precise prediction. A steady solution master equation, first calculation for open system, illustrates method circumvent detection upon measured frequency.

Detector-induced backaction on the counting statistics of a double quantum dot
Full counting statistics of electron transport is of fundamental importance for a deeper understanding of the underlying physical processes in quantum transport in nanoscale devices. The backaction effect from a detector on the nanoscale devices is also essential due to its inevitable presence in experiments. Here we investigate the backaction of a charge detector in the form of a quantum point...

متن کاملQuantifying the Quantum Backaction of a Non-Linear Dispersive Measurement
Quantum mechanics emerged triumphantly in the 1920s as a unifying explanation for a century’s worth of experiments: Michael Faraday’s discovery of cathode rays in 1838, blackbody radiation, and of course the photoelectric effect. The quantum explanation for all of these effects lies in a detailed understanding of a single atom and its interaction with light. What is surprising, however, is that...

Semiconductor-based quantum structures integrated into mechanical resonators have emerged as a unique platform for generating entanglement between macroscopic phononic and mesocopic electronic degrees of freedom. A key challenge to realizing this is the ability to create and control the coupling between two vastly dissimilar systems. Here, such coupling is demonstrated in a hybrid device compos...
