Ab Initio Architectonics

In the paper's words

The current paradigm of quantum computing is increasingly constrained by a reliance on emergent quasiparticle ontologies and “epistemic patches” that obscure the underlying ab initio dynamics of quantum materials. This paper proposes a radical realignment through the “Signal-Worker” (S-W) framework, which distinguishes between fundamental fermionic workers (electrons) and bosonic signals (photons/forces). We critique the artificial truncation of fluxonium qutrit arrays and contrast them with the passive structural coherence of twistronic and Kagome lattices.

1. Millimeter-wave tuning (100 GHz) enhances coherence and readout fidelity, as demonstrated by Yale (2021).

2. The high SNR ensures that the readout fidelity remains above 95% even at higher “ambient” temperatures.

6. In the S-W framework, the 100 GHz signal is a high-frequency “coordination signal” that enhances the worker-signal synchronization.

How it is done

1. This “active” approach is a form of “rented” coherence that requires a constant input of external signals to maintain the quantum state.

   from 1.1 The Crisis of

2. While this approach is pragmatically useful, it is an epistemic choice that ignores the continuous nature of the underlying material lattice.

   from 1.2 Fluxonium and the

3. This is a “bottom-up” approach that contrasts with the “top-down” effective theory approach.

   from 1.3 The Signal-Worker (S-W)

4. The scalability of this approach is limited only by our ability to fabricate large-area, high-quality heterostructures.

What would falsify it

1. Unlike standard BCS theory, which treats the environment as a dissipative bath, the S-W framework predicts a “Coherence Ownership” threshold where certain lattice symmetries can suppress decoherence.

   from 4.1

2. For a Kagome lattice at 77K, S-W predicts a high coherence retention due to structural shielding, whereas BCS would predict a collapse.

Where the claim stops

1. Work The identification of limitations and future work is essential for providing a balanced and productive vision for the architectonic era.

   from 5.4 Limitations and Future

2. By focusing on these areas, future work can accelerate the transition to ambient operation.

   from 5.4 Limitations and Future

3. However, this critique is addressed by the fact that the “coherence crisis” of superconducting circuits is a fundamental physical limit, while the manufacturing challenges of 2D materials are technical hurdles.
