Noise-induced quantum-circuit refrigeration
Heidi Kivijärvi, Arto Viitanen, Timm Mörstedt +1
We use a transmon qubit and its dispersively coupled readout resonator to measure the Fock state populations of another microwave resonator, to which we have attached a quantum-cir…
Rapid on-demand generation of thermal states in superconducting quantum circuits
Timm Fabian Mörstedt, Wallace Santos Teixeira, Arto Viitanen +13
We experimentally demonstrate the fast generation of thermal states of a transmon using a single-junction quantum-circuit refrigerator (QCR) as an in-situ-tunable environment. Thro…
Many-excitation removal of a transmon qubit using a single-junction quantum-circuit refrigerator and a two-tone microwave drive
Wallace Teixeira, Timm Mörstedt, Arto Viitanen +7
Achieving fast and precise initialization of qubits is a critical requirement for the successful operation of quantum computers. The combination of engineered environments with all…
