The emerging quantum technological applications call for fast and accurate initialization of the corresponding devices to low-entropy states. To this end, we theoretically study a recently demonstrated quantum-circuit refrigerator in case nonlinear electric circuits such as superconducting qubits. maximum refrigeration rate transmon flux qubits is observed be roughly an order magnitude higher than that usual linear resonators, increasing flexibility design. We find typical experimental...
We present here our recent results on qubit reset scheme based a quantum-circuit refrigerator (QCR). In particular, we use the photon-assisted quasiparticle tunneling through superconductor--insulator--normal-metal--insulator--superconductor junction to controllably decrease energy relaxation time of during QCR operation. experiment, transmon with dispersive readout. The is capacitively coupled its normal-metal island. employ rapid, square-shaped control voltage pulses durations in range...
Previous studies of photon-assisted tunneling through normal-metal–insulator–superconductor junctions have exhibited potential for providing a convenient tool to control the dissipation quantum-electric circuits in situ. However, current literature on such quantum-circuit refrigerator (QCR) does not present detailed description charge dynamics processes or phase coherence open quantum system. Here, we derive master equation describing both and degrees freedom, discover that typical...
Quantum computing has tremendous potential to overcome some of the fundamental limitations present in classical information processing. Yet, today's technological quality and scaling prevent exploiting its full potential. based on superconducting quantum processing units (QPUs) is among most promising approaches towards practical advantage. In this article basic approach IQM Computers described covering both QPU rest full-stack computer. particular, focus a 20-qubit computer featuring Garnet...
Here, we discuss the development of an all-wet back-channel etch process chemistry with high metal selectivity that is capable shaping structures IGZO TFT to customer specifications. Our approach involves a two-step etching first selectively removes only conductor (Cu) while temporarily stopping at underlying adhesion layer (Mo or Ti). The then minimal impact semiconductor. By pursuing approach, where each designed target specific selectivity, risk excessive undercutting generally associated...
