An error model of under- or over-rotation of the signal processing operator parameterized by is introduced. Model for which the approximation incurs only $O(q^w)$ error for some integer We present a first step in achieving error correction at the level of quantum algorithms by combining a unified perspective on modern quantum algorithms via quantum signal processing (QSP). ![]() These errors can be mitigated by classical postprocessing given theĪccess of an experimental \emph\big)\right)$, which we motivate using a simplified error To the empirical probability distribution sampled from the output of a quantumĬircuit.

The main issue of quantum error correction techniques are that generally they require a large overhead in terms of additional qubits on top of those required. ![]()
