Engineering multi-photon dissipation with a dc-voltage-biased Josephson junction
Marco Paradina, Ambroise Peugeot, Roberto Negrin +8
Multi-photon dissipation -- a key resource for bosonic qubits -- is usually realized by parametrically pumping a Josephson coupler at the cost of spurious nonlinear terms. Here we…
