Josephson junctions (JJs) with Josephson energy \(E_J \lesssim 1K\) are widely employed as non-linear elements in superconducting circuits for quantum computing, operating at milli-Kelvin temperatures. Here we experimentally study incoherent phase slips (IPS) in low-\(E_J\) Aluminum-based JJs at \(T...
