- Abstract: In this work we propose the generation of a hybrid entangled resource (HER)
and its further application in a quantum teleportation scheme from an
experimentally feasible point of view. The source for HER preparation is based
on the four wave mixing process in a photonic crystal fiber, from which one
party of its output bipartite state is used to herald a single photon or a
single photon added coherent state. From the heralded state and linear optics
the HER is created. In the proposed teleportation protocol Bob uses the HER to
teleport qubits with different spectral properties. Bob makes a Bell
measurement in the single photon basis and characterizes the scheme with its
average quantum teleportation fidelity. Fidelities close to one are expected
for qubits in a wide spectral range. The work also includes a discussion about
the fidelity dependence on the geometrical properties of the medium through
which the HER is generated. An important remark is that no spectral filtering
is employed in the heralding process, which emphasizes the feasibility of this
scheme without compromising photon flux.

We propose a scheme to teleport a continuous variable optical qubit, encoded in an optical qumode, onto a discrete variable solid-state qubit, associated with a single nitrogen-vacancy center spin in diamond, via a hybrid entanglement.
We find that the average teleportation fidelity can still exceed the classical limit, enabling substantial teleportation distances under realistic experimental conditions.

This work employs a bright QD single-photon source to generate a complete set of quantum states for information processing with OAM photons.
We first study the hybrid intra-particle entanglement between the OAM and the polarization degree of freedom of a single-photon.
Then, we investigate the hybrid inter-particle entanglement, by exploiting a probabilistic two qudit OAM-based entangling gate.
