Deterministic and cascadable conditional phase gate for photonic qubits
Previous analyses of conditional φ[subscript nl]-phase gates for photonic qubits that treat cross-phase modulation (XPM) in a causal, multimode, quantum field setting suggest that a large (∼π rad) nonlinear phase shift is always accompanied by fidelity-degrading noise [J. H. Shapiro, Phys. Rev. A 73...
