Scalable quantum computation with cavity QED systems
Vittorio Giovannetti, David Vitali, P. Tombesi, ARTUR K. EKERT · Physical Review A · 2000
We propose a scheme for quantum computing using high-$Q$ cavities in which the qubits are represented by single-cavity modes restricted in the space spanned by the two lowest Fock states. We show that single-qubit operations and universal multiple qubit gates can be implemented using atoms sequentially crossing the cavities.
