    "abstract": "Decoherence is the main obstacle to the realization of quantum computers.\nUntil recently it was thought that quantum error correcting codes are the only\ncomplete solution to the decoherence problem. Here we present an alternative\nthat is based on a combination of a decoherence-free subspace encoding and the\napplication of strong and fast pulses: ``encoded recoupling and decoupling\u0027\u0027\n(ERD). This alternative has the advantage of lower encoding overhead (as few as\ntwo physical qubits per logical qubit suffice), and direct application to a\nnumber of promising proposals for the experimental realization of quantum\ncomputers.",
