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

[Joseph D Touch <[e-mail]>]

FWIW, IMO, your second premise is false, especially as it relates to how packets flow through devices, as you show later in your approach – which, FWIW, revisits the approach already attempted in numerous optical network switch designs (and has proven less than useful for a reason).

Some of the other claims are also dubious; the QIRG arch doc does include descriptions of switches for quantum nets (I added it; Sec 5.3.2), e.g., there HAS been an “equivalent design proposed analogous to packet switching”. In fact, the entire doc appears to ignore this RG’s arch doc.

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

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://techblog.cisco.com/blog/making-a-quantum-ready-internet%20/>  /  https://arxiv.org/pdf/2205.07507.pdf 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

Kind Regards
Patrick
