1. A method for improving fidelity of a quantum operation on a quantum bit of interest, comprising: performing respective controlled quantum gate operations using physical qubit assemblies and a corresponding control, each controlled by the quantum bit of interest, on a plurality of ancillary quantum bits; measuring an energy state of each of the plurality of ancillary quantum bit to facilitate the improvement of the fidelity of the quantum operation; and determining one of an energy state of the quantum bit of interest and an effectiveness of the quantum operation based on the energy states of a majority of the ancillary quantum bits.
