Quantum error correction of systematic errors using a quantum search framework
Ben W. Reichardt, Lov K. Grover · Physical Review A · 2005
Composite pulses are a quantum control technique for canceling out systematic control errors. We present a different composite pulse sequence inspired by quantum search. Our technique can correct a wider variety of systematic errors---including, for example, nonlinear over-rotational errors---than previous techniques. Concatenation of the pulse sequence can reduce a systematic error to an arbitrarily small level.
