The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We demonstrate a CMOS-compatible, centimetre-scale, multi-band on-chip THz data link achieving an aggregate throughput of 1.004 Tbps. The performance is enabled by suppressing Bragg-induced stopbands using dispersion-engineered, effective-medium-supported unclad silicon waveguides, resulting in flat transmission and low-ripple group delay across multiple THz bands.

C2weakest assumption

That the dispersion-engineered effective-medium-supported unclad silicon waveguides will reliably suppress Bragg stopbands and deliver the stated low propagation loss, bending loss, and GVD (0.15 ps²/mm) over the full 220-500 GHz band in fabricated devices without unaccounted penalties.

C3one line summary

Demonstrates dispersion-engineered unclad silicon THz waveguides enabling 1.004 Tbps aggregate throughput across multiple bands with low GVD and dual-polarization support in a CMOS-compatible platform.
