Dr Vadim Vorobev was our guest for the February 2021 QuSCo on-air session with his talk “Quantum measurements and quantum computation with electron-nuclear spin quantum register.”

Abstract:

The problem of quantum measurements stands as an independent fundamental problem since the Gedanken Stern-Gerlach experiment. The collapse of the wave function was the main triggering source of numerous scientific debates. Different tractations were adopted, and eventually, up to now the concept of generalized quantum measurements is accepted which be the central line in our discussion.  In our lecture, we will consider a simplified model of a quantum spin bath, probed with a quantum sensor – ancilla.

The possible scenarios of measurements would be discussed, including generalized weak measurements, and quantum phase estimation.  By the end of the lecture, you will learn the main concepts of generalized measurements,  measurement induced quantum back-action and its influence on applications as well as the ways to control it.
