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…
Quantum-circuit refrigeration of a superconducting microwave resonator well below a single quantum
Arto Viitanen, Timm Mörstedt, Wallace S. Teixeira +4
We experimentally demonstrate a recently proposed single-junction quantum-circuit refrigerator (QCR) as an in-situ-tunable low-temperature environment for a superconducting 4.7-GHz…
Long-distance transmon coupler with CZ gate fidelity above
Fabian Marxer, Antti Vepsäläinen, Shan W. Jolin +36
Tunable coupling of superconducting qubits has been widely studied due to its importance for isolated gate operations in scalable quantum processor architectures. Here, we demonstr…
