Port-based teleportation of continuous quantum variables
Quantum teleportation allows to transmit quantum information using classical information and entanglement only. Port-based teleportation is a variation of this procedure that involves simpler recovery operations to obtain the transmitted quantum information. This provides significant advantages in different applications such as instantaneous non-local computation. We study port-based teleportation for continuous variable systems. We connect this problem to hypothesis testing, generalizing a result already known for finite-dimensional systems. Similarly, we present a relation between entanglement fidelity and average fidelity valid for both finite and infinite-dimensional systems. Finally, we present a protocol that reduces port-based teleportation for infinite-dimensional systems to port-based teleportation of finite-dimensional systems which allows us to show that the former task is, at least in principle, possible with a finite amount of resources.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
