Cross-Architecture Quantum Teleportation via Hyperelliptic Curve Topology: Experimental Demonstration on Commercial QPUs

We report the first successful quantum tele-portation protocol between heterogeneousquantum processing units (QPUs) usingalgebraic-geometric structure as the entan-glement modulation framework. A 5-qubitquantum state was teleported from RigettiComputing’s Ankaa-3 superconducting QPUto IQM Quantum Computers’ Emerald su-perconducting QPU, achieving 80% bit-levelfidelity using only classical communicationchannels. The protocol employs eigen-phases extracted from the period matrix ofgenus-2 hyperelliptic curves to encode quan-tum correlation structure in a hardware-agnostic manner. Our implementation uti-lizes a novel database-coordinated classi-cal channel for Bell measurement trans-mission, demonstrating that standard dis-tributed systems infrastructure can supportquantum networking protocols.

We present comprehensive experimen-tal data, theoretical analysis, and a scal-able framework for heterogeneous quantumnetwork construction.
