    "abstract": "Decoherence-free subspaces allow for the preparation of coherent and\nentangled qubits for quantum computing. Decoherence can be dramatically\nreduced, yet dissipation is an integral part of the scheme in generating stable\nqubits and manipulating them via one and two bit gate operations. How this\nworks can be understood by comparing the system with a three-level atom\nexhibiting a macroscopic dark period. In addition, a dynamical explanation is\ngiven for a scheme based on atoms inside an optical cavity in the strong\ncoupling regime and we show how spontaneous emission by the atoms can be highly\nsuppressed.",
