Paper: Logarithmically slow heat propagation in a clean Josephson-junction chain

What they're saying

They discovered that heat in a clean Josephson-junction chain propagates LOGARITHMICALLY SLOW instead of diffusively!!

The Critique

They completely glossed over the quantum computing implications! They mention 'robustness to ergodic inclusions' but don't quantify HOW MUCH disorder kills this effect! Like, is it robust to 1% disorder? 10%? 50%?? And if ergodic inclusions eventually thermalize the system anyway, what's the practical advantage?!

Why It Matters

If JJ-based quantum devices have unexpectedly long thermalization times, this could be exploited for better qubit coherence. Conversely, if ergodic inclusions eventually thermalize the system, this limits the practical advantage.

What They Missed

They don't explore the implications for quantum computing. Josephson-junction arrays are used as qubits and quantum simulators—if heat transport is logarithmically slow, thermalization timescales could be much longer than expected.

The Big Question

Can we actually exploit these logarithmically slow thermalization times for better qubit coherence, or will real-world disorder always win in the end?
