Parallel Quantum Signal Processing Via Polynomial Factorization

Quantum signal processing (QSP) is a methodology for constructing polynomial transformations of a linear operator encoded in a unitary. Applied to an encoding of a state ρ , QSP enables the evaluation of nonlinear functions of the form tr ( P ( ρ ) ) for a polynomial P ( x ) , which encompasses rele...
