Some Remarks on Noncollapsing Target’s State in an Ideal Weak Measurement

  • Published:
Journal of Russian Laser Research Aims and scope

Abstract

We review the concept of strong and weak measurements and show that one can find eigenvalues and the related probability distribution of an observable, no matter how strong the measurement is. Considering the reduced density operator of the measurement device, we demonstrate that exact invariance of the target’s quantum state has physical consequences that are not true.
