A coherent two-level system residing in the tunable coupler is shown to couple simultaneously to two distant qubits, producing tunable non-local non-Markovian decoherence and a 1/f noise spectrum spanning ten orders of magnitude.

LIMINAL fits nested Lindblad models to tomographic data and uses likelihood-ratio tests to identify minimal dynamics for a five-qubit superconducting processor, supporting three-local Hamiltonian terms and two-local dissipation but not three-local dissipation.
Tunneling splittings for H and D in bcc Nb match experiment only in a 5D nonadiabatic lattice-renormalized Born-Oppenheimer model; adiabatic separation holds solely in the muon mass limit.
Optimization of doping, bias, and geometry in SiC p-i-n diodes reduces charge noise and optical linewidth for embedded divacancy spin centers, with a new leakage-current noise formalism mitigated by defect placement away from surfaces.
