Correcting quantum errors with the Zeno effect

The study to reduce and correcting quantum errors with the help of error correction codes was discussed. Quantum error correction schemes based on encoding consists of the various steps which includes encoding n logical qubits into m>n physical ones, introduction of errors, syndrome measurement and error correction. The error correction codes could correct the errors corresponding to the first few orders in the Taylor expansion of the time evolution operators corresponding to the Hamiltonian of the interaction with the environment. It was found that 'Zero regime' codes with less redundancy are sufficient to reduce and correcting quantum errors.
