Measurement Back-Action in Quantum Point-Contact Charge Sensing

Measurement Back-Action in Quantum Point-Contact Charge Sensing

Charge sensing with quantum point-contacts (QPCs) is a technique widely used in semiconductor quantum-dot research. Understanding the physics of this measurement process, as well as finding ways of suppressing unwanted measurement back-action, are therefore both desirable. In this article, we presen...
