Error Avoiding Quantum Codes


The existence is proved of a class of open quantum systems that admits a linear subspace C of the space of states such that the restriction of the dynamical semigroup to the states built over C is unitary. Such subspace allows for error-avoiding (noiseless) enconding of quantum information. PACS numbers: 71.10.Ad , 05.30.Fk
