Preparation of engineered two-photon entangled states for multidimensional quantum information

Abstract: We put forward an experimentally feasible technique to generate engineered entangled states in d-dimensional Hilbert spaces in parametric down-conversion of photons. The scheme is based on the orbital angular momentum of light and translates the classical, topological information imprinted in the light beam that pumps the two-photon source into quantum information contained in the weights and phases of the quantum entangled two-photon states.Peer ReviewedPostprint (published version

“…In contrast, Eq. (12) shows that the required quantum state could be obtained through appropriate engineering of the spatial properties of the pump beam [26]. It also shows that the phase of the state |n, n > corresponds to the phase of the corresponding mode of the classical pump beam, arg{C 2n }, a result consistent with the experimental observation by Ou et.…”

“…In fact, this source also produces frequency entangled [245][246][247] and both linear [248,249] and orbital angular momentum entangled [250][251][252][253][254][255] photon pairs. In our case, we will use photon pairs produced by SPDC to propose a novel method to swap linear momentum entanglement into polarization entanglement by means of CR.…”

“…(6) and (7), we have utilized the relation C −ℓ,ℓ = C ℓ,−ℓ , owing to the symmetry of the SPDC process [38]. In contrast to the case with only a single pair of hybrid entangled photons, here we have two pairs and thus we could write the combined state as…”
