A case study against QSVT: assessment of quantum phase estimation improved by signal processing techniques
Sean Greenaway, William Pol, Sukin Sim
In recent years, quantum algorithms have been proposed which use quantum phase estimation (QPE) coherently as a subroutine without measurement. In order to do this effectively, the…
