Simultaneous Estimation of Nonlinear Functionals of a Quantum State

Kean Chen, Qisheng Wang, Zhan Yu +1

We consider a fundamental task in quantum information theory, estimating the values of $t r (O ρ)$ , $t r (O ρ^{2})$ , $\dots$ , $t r (O ρ^{k})$ for an observable $O$ and a quantum state $ρ$ . We…

Exploring experimental limit of deep quantum signal processing using a trapped-ion simulator

J. -T. Bu, Lei Zhang, Zhan Yu +12

Quantum signal processing (QSP), which enables systematic polynomial transformations on quantum data through sequences of qubit rotations, has emerged as a fundamental building blo…
