    "abstract": "A general strategy to maintain the coherence of a quantum bit is proposed.\nThe analytical result is derived rigorously including all memory and\nback-action effects. It is based on an optimized $\\pi$-pulse sequence for\ndynamic decoupling extending the Carr-Purcell-Meiboom-Gill (CPMG) cycle. The\noptimized sequence is very efficient, in particular for strong couplings to the\nenvironment.",
