Re: [Qirg] Fwd: [Quantum packet] Quantum frame structure to unified Internet for Classical and Quantum Communication

[Gelard Patrick <[e-mail]>]

Dear Stephen,

Your concept of “Quantum frame structure” is interesting to be known.

Now, for long distance communications it is necessary to correct the quantum information to be able to relay it. This therefore requires progress on quantum error correction scheme to have a reliable transmission of quantum information over a quantum relay channel which is a hard task due to the limitations of the no-cloning theorem.

Will switches based on error correction code techniques to relay quantum information emerge before switches based on entanglement swapping techniques ?

Hi All,

Thanks for the interest in the paper and thanks Wojtek for explaining that.

Indeed we believe the proposal doesn't exclude entanglement swapping-based networks, this would just be a change in how the channels connecting nodes are allocated for transportation. This could also potentially reduce the number of total swaps needed to create the end-to-end entanglement as some nodes could simply relay quantum data, rather than storing entanglement at each intermediate node.

We included a preliminary analysis of entanglement distribution under the "quantum packet" model, which may give further clarification.

Further, the point you make Wojtek regarding swapping at the boundary, we have discussed a bit in a similar line in the paper in the last section.

If there is interest and capacity, I could present the paper to the group.

Thank you,
Stephen
