Bolometer operating at the threshold for circuit quantum electrodynamics
R. Kokkoniemi, J. -P. Girard, D. Hazra +7
Radiation sensors based on the heating effect of the absorbed radiation are typically relatively simple to operate and flexible in terms of the input frequency. Consequently, they…
Photon-number-dependent effective Lamb shift
Arto Viitanen, Matti Silveri, Máté Jenei +8
The Lamb shift, an energy shift arising from the presence of the electromagnetic vacuum, has been observed in various quantum systems and established as the part of the energy shif…
Pauli Blockade in Silicon Quantum Dots with Spin-Orbit Control
Amanda Seedhouse, Tuomo Tanttu, Ross C. C. Leon +12
Quantum computation relies on accurate measurements of qubits not only for reading the output of the calculation, but also to perform error correction. Most proposed scalable silic…
Broadband Tunable Phase Shifter For Microwaves
Jinli Zhang, Tianyi Li, Roope Kokkoniemi +8
We implement a broadly tunable phase shifter for microwaves based on superconducting quantum interference devices (SQUIDs) and study it both experimentally and theoretically. At di…
