    "abstract": "We present a protocol to construct an arbitrary quantum circuit. The quantum\nbits (qubits) are encoded in polarisation states of single photons. They are\nstored in spatially separated dense media deposed in an optical cavity.\nSpecific sequences of pulses address individually the storage media to encode\nthe qubits and to implement a universal set of gates. The proposed protocol is\ndecoherence-free in the sense that spontaneous emission and cavity damping are\navoided. We discuss a coupling scheme for experimental implementation in Neon\natoms.",
