Author(s): Christopher Corlett, Ieva Čepaitė, Andrew J. Daley, Cica Gustiani, Gerard Pelegrí, Jonathan D. Pritchard, Noah Linden, and Paul Skrzypczyk A new scheme can speed up quantum measurement in different physical platforms through a space-time trade-off — using additional ancillary qubits in place of longer measurement time.
