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

[Gelard Patrick <[e-mail]>]

Yes, what I meant, is that the packet-switching approach (base on Quantum frame structure), proposed in the paper, seems unable to be used to harness entanglement swapping.

And thus the concept of "quantum packet/frame" can it be useful in an  distribution method based on "entanglement swapping" ?

Not necessarily. One can always distribute entanglement via direct transmission (or any other method) over some distance and then stitch groups of these with entanglement swapping. Completely of the top of my head so I haven't thought this through, but one could perhaps use direct transmission within a network, but entanglement swap at boundaries with other networks. Either way, my point was that I don't think it's an either/or situation.

Thanks for this fix.

Note that the approach proposed in the paper is not compatible with an entanglement distribution based on the technique of "entanglement swapping".

Hi, for some reason the URL encoded for the first link encodes a "%20" space at the end, resulting in a 404. This seems to work: https://techblog.cisco.com/blog/making-a-quantum-ready-internet/<https://urldefense.com/v3/__https:/techblog.cisco.com/blog/making-a-quantum-ready-internet/__;!!PAKc-5URQlI!6k225HWelkGQr7Df6JZOAuRQ778MvDUUA1oNn0u1yNPwSKNwHEPcunBSTyAbB905OxebTFckbByH1MU3Vyxe1IRdOaeKW8_5$>

Dear Qirg group,



For information, a « Classical-Quantum Hybrid Frame Structure » proposed by Cisco (Stephen DiAdamo Et al) https://techblog.cisco.com/blog/making-a-quantum-ready-internet <https://urldefense.com/v3/__https:/techblog.cisco.com/blog/making-a-quantum-ready-internet*20/__;JQ!!PAKc-5URQlI!6k225HWelkGQr7Df6JZOAuRQ778MvDUUA1oNn0u1yNPwSKNwHEPcunBSTyAbB905OxebTFckbByH1MU3Vyxe1IRdOcQvv6eG$>  /  https://arxiv.org/pdf/2205.07507.pdf<https://urldefense.com/v3/__https:/arxiv.org/pdf/2205.07507.pdf__;!!PAKc-5URQlI!6k225HWelkGQr7Df6JZOAuRQ778MvDUUA1oNn0u1yNPwSKNwHEPcunBSTyAbB905OxebTFckbByH1MU3Vyxe1IRdOctq8P0V$> to unified Internet for Classical and Quantum Communication :



FIG. 1. Quantum frame structure. The frame is composed of three components: A classical header, a quantum payload, and a classical trailer.

The classical header and trailer ([PG]classical control plan)  and the ([PG] physical/wave packet) quantum payload can be generated using different photonic sources and multiplexed into a hybrid data frame by using a different degree of freedom of light, such as time, wavelength, polarization, spatial mode, and so on, or any combinations of them
