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 first derive general analytical conditions under which arbitrary qubit decays can be mapped to wavevector-dependent couplings that guarantee perfect state transfer in the continuum limit of infinitely many coupling points. Then, for experimentally relevant configurations with a finite number of coupling points, we demonstrate that high transfer fidelities can still be achieved by optimization, reaching 87% with only two coupling points and exceeding 99% with ten or more.

C2weakest assumption

That the nonlocal interaction engineered via finite coupling points can be optimized to produce sufficiently time-reversal-symmetric wavepackets for high-fidelity transfer, without post-hoc data selection or unstated constraints on the optimization landscape.

C3one line summary

Giant atoms in waveguides enable high-fidelity passive quantum state transfer via optimized nonlocal couplings, reaching 87% with two points and over 99% with ten or more.
