Absorptive Quantum Measurements via Coherently Coupled Quantum Dots
Gerard J Milburn, Haoyu Sun, Ben Upcroft · Australian Journal of Physics · 2001
We propose an absorptive measurement scheme via coupled quantum dots based on studies of the quantum dynamics of coherently coupled dots. The system is described through a Markov master equation that is related to a measurable quantity, the current. We analyse the measurement configuration and calculate the correlations and noise spectra beyond the adiabatic approximation.
