Quantum computing with incoherent resources and quantum jumps

Santos, Marcelo Franca; Terra Cunha, T; Chaves, R; Carvalho, Andre


Spontaneous emission and the inelastic scattering of photons are two natural processes usually associated with decoherence and the reduction in the capacity to process quantum information. Here we show that, when suitably detected, these photons are sufficient to build all the fundamental blocks needed to perform quantum computation in the emitting qubits while protecting them from deleterious dissipative effects. We exemplify this by showing how to efficiently prepare graph states for the...[Show more]
