After years of efforts,

The Energy-Participation Ratio (EPR) for the design and quantization of a #quantumcomputing chip now on the #arXiv

Glad the EPR method seems to already be useful to some 25+ groups…

“Where is the energy?”

is the only question you need to ask & answer to design both the dissipative budget and the quantum #Hamiltonian of any #quantum device

— irrelevant of its topology or the constitution of its nonlinear elements.
The answer to this question is the Energy-Participation Ratio (EPR) p — a number between 0 and 1,

which says how much of the energy of a mode is stored in a nonlinear element (e.g., Josephson junction).

The EPR is the key to the classical-to-quantum bridge for #quantumcircuits
