Conditional phase gate between two photons through control of the interaction time with a single atom in a cavity
Arkan Hassan, Julio Gea-Banacloche
We show that the simultaneous interaction of two single-photon fields with a single atom in the V configuration can in principle produce a conditional phase gate of arbitrarily hig…
Input-output wavepacket description of two photons interacting with a V-type three-level atom in an optical cavity
Arkan Hassan, Julio Gea-Banacloche
We study the interaction of a V-type atom in a cavity with incident single- and two-photon wavepackets and derive an exact formula, valid in all parameter regimes, relating the spe…
Stimulated emission of superradiant atoms in waveguide QED
Rui Asaoka, Julio Gea-Banacloche, Yuuki Tokunaga +1
We investigate the stimulated emission of superradiant atoms coupled to a waveguide induced by a coherent-state photon pulse. We provide an analytical result when a short pulse…
Passive, deterministic photonic CPHASE gate via two-level systems
William Konyk, Julio Gea-Banacloche
We show that an array of identical two level systems coupled losslessly to a one dimensional waveguide is able to realize a high fidelity conditional phase shift useful for quantum…
Analytical results for a conditional phase shift between single-photon pulses in a nonlocal nonlinear medium
Balakrishnan Viswanathan, Julio Gea-Banacloche
It has been suggested that second-order nonlinearities could be used for quantum logic at the single-photon level. Specifically, successive two-photon processes in principle could…
One- and Two-Photon Scattering by Two Atoms in a Waveguide
William Konyk, Julio Gea-Banacloche
We consider the interaction of one- and two-photon pulses in a waveguide with two two-level systems (TLS) that are also able to interact directly either through an exchange- or a d…
