“…Therefore the correlation between the two photons can be more clearly observed in the LR and LL channels. This is in contrast to scattering with indistinguishable photons in related systems where the corresponding two-photon correlation term cannot be separated out completely in the transmission and reflection amplitudes [32,38]. p + (B) q = 0, which is a constraint of energy conservation, and the width depends on the spectral widths of the incident photon wave packets and the coupling constants according to the energy denominators in Eq.…”

We investigate theoretically quantum scattering of two distinguishable photon wave packets from a -type three-level atom in a one-dimensional waveguide. The quantum state of scattered photons is solved analytically, and the solution indicates how the two photons become strongly correlated after the scattering. We determine the two-photon reflection and transmission properties, and analyze the quantum entanglement between the scattered photons. In particular, we show that the degree of entanglement can be enhanced by decreasing the spectral width of the incident photon wave packets.

“…One of the interesting topics in waveguide QED is correlated transport of photons when two or more photons interact with each other inside the waveguide [30][31][32][33][34][35][36][37][38][39]. The photonphoton interaction is mediated by atoms.…”

“…These include fully numerical approaches [15,23], as well as analytic approaches such as the input-output formalism [16], the real-space Bethe ansatz [24], the Lehmann-Symanzik-Zimmermann formalism [25], Laplace transforms [26], a wave-function-based approach [20,27], and master equation formalisms [18]. Several of these approaches allow for analytic determination of single-and two-photon scattering-matrix elements, which directly relate the scattered state to the initial state of the system.…”

Strong nonlinearity-induced correlations for counterpropagating photons scattering on a two-level emitter

We analytically treat the scattering of two counterpropagating photons on a two-level emitter embedded in an optical waveguide. We find that the nonlinearity of the emitter can give rise to significant pulse-dependent directional correlations in the scattered photonic state, which could be quantified via a reduction in coincidence clicks in a Hong-Ou-Mandel measurement setup, analogous to a linear beam splitter. Changes to the spectra and phase of the scattered photons, however, would lead to reduced interference with other photons when implemented in a larger optical circuit. We introduce suitable fidelity measures which account for these changes and find that high values can still be achieved even when accounting for all properties of the scattered photonic state.

“…Some novel quantum devices have been achieved due to dipole blockade, for example one can use it to make a light source with single photon and design single-photon subtractors and light switch with single photon [7]. There has a prediction on the form For a Wigner crystal of individual photon, Refs.…”
