Optimal Tight Frames and Quantum Measurement
Y. C. Eldar, G. David Forney
Tight frames and rank-one quantum measurements are shown to be intimately related. In fact, the family of normalized tight frames for the space in which a quantum mechanical system…

On Quantum Detection and the Square-Root Measurement
Yonina C. Eldar, G. David Forney
In this paper we consider the problem of constructing measurements optimized to distinguish between a collection of possibly non-orthogonal quantum states. We consider a collection…
