Abstract
We describe a scheme for quantum error correction that employs feedback and weak measurement. This provides a method of protecting an unknown quantum state against errors that does not use the standard tools of quantum error correction - projective measurements and fast controlled unitary gates - and is practicably implementable because of the little side processing required. We evaluate the performance of our scheme by simulating a simple scenario of protection against bit-flips.
