Bell-state measurement and quantum teleportation using linear optics:
two-photon pairs, entangled coherent states, and hybrid entanglement
   [PDF]

Seung-Woo Lee, Hyunseok Jeong
We review and compare Bell-state measurement and quantum teleportation schemes using linear optics with three different types of resources, i.e., two-photon pairs, entangled coherent states and hybrid entangled states. Remarkably, perfect teleportation with linear optics is possible in principle based on a hybrid approach that combines two-photon pairs and entangled coherent states. It turns out that hybrid approach allows to perform Bell-state measurement and local Pauli operations in a deterministic way, while it requires photon number resolving measurements.
