Fundamental Coherence Limits in Google and IBM Quantum Architectures via ψ-field Rheology

This paper presents a theoretical substantiation of the fundamental limit of quantum coherence in superconducting qubit architectures (exemplified by Google Sycamore and IBM Falcon chips). Within the framework of the Fermionic Universe Hypothesis (FUH), decoherence is treated not as a result of material technological imperfections (TLS model), but as the dissipation of excitation energy into a viscous vacuum condensate (η = 1.2 × 10^−15 Pa·s). It is established that the observed ”plateau” in qubit lifetimes (T1 ≈ 50–150 µs) corresponds to the calculated limit of viscous friction. An experimental protocol is proposed to overcome this barrier by initiating a local phase transition of the vacuum into a superfluid state upon reaching the injection energy threshold E > 7.76 keV (the Shlyapik effect).
