In-situ tunable nonlinearity and competing signal paths in coupled superconducting resonators
Michael Fischer, Qi-Ming Chen, Christian Besson +10
We have fabricated and studied a system of two tunable and coupled nonlinear superconducting resonators. The nonlinearity is introduced by galvanically coupled dc-SQUIDs. We simula…
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…
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…
