"tune energy and rate of quasiparticle injections via bias voltage and tunneling current... injected power and injection rate yield reduced critical current on nanowire... STM to locate and measure nanodevice... each quasiparticle injected relaxed energy to phonons, broke hundreds of Cooper pairs generate out-of-equilibrium quasiparticles formed hotspot... injecting quasiparticle current several magnitudes lower... field-effect transistors and photon detectors, superconducting quantum circuits"
