Query: Sequential measurements of conjugate observables   We present a unified treatment of sequential measurements of two conjugate
observables. Our approach is to derive a mathematical structure theorem for all
the relevant covariant instruments. As a consequence of this result, we show
that every Weyl-Heisenberg covariant observable can be implemented as a
sequential measurement of two conjugate observables. This method is applicable
both in finite and infinite dimensional Hilbert spaces, therefore covering
sequential spin component measurements as well as position-momentum sequential
measurements.
