Fast control of dissipation in a superconducting resonator
Vasilii Sevriuk, Kuan Yen Tan, Eric Hyyppä +8
We report on fast tunability of an electromagnetic environment coupled to a superconducting coplanar waveguide resonator. Namely, we utilize a recently-developed quantum-circuit re…
A low-noise on-chip coherent microwave source
Chengyu Yan, Juha Hassel, Visa Vesterinen +5
The scaleup of quantum computers operating in the microwave domain requires advanced control electronics, and the use of integrated components that operate at the temperature of th…
Tunable refrigerator for non-linear quantum electric circuits
Hao Hsu, Matti Silveri, András Gunyhó +3
The emerging quantum technological applications call for fast and accurate initialization of the corresponding devices to low-entropy quantum states. To this end, we theoretically…
Compact 3D quantum memory
Edwar Xie, Frank Deppe, Michael Renger +8
Superconducting 3D microwave cavities offer state-of-the-art coherence times and a well controlled environment for superconducting qubits. In order to realize at the same time fast…
Optimized heat transfer at exceptional points in quantum circuits
Matti Partanen, Jan Goetz, Kuan Yen Tan +12
Superconducting quantum circuits are potential candidates to realize a large-scale quantum computer. The envisioned large density of integrated components, however, requires a prop…
Parity-Engineered Light-Matter Interaction
Jan Goetz, Frank Deppe, Kirill G. Fedorov +6
The concept of parity describes the inversion symmetry of a system and is of fundamental relevance in the standard model, quantum information processing, and field theory. In quant…
