High-power readout of a transmon qubit using a nonlinear coupling
Cyril Mori, Vladimir Milchakov, Francesca D'Esposito +13
The field of superconducting qubits is constantly evolving with new circuit designs. However, when it comes to qubit readout, the use of simple transverse linear coupling remains o…
A Superconducting Qubit-Resonator Quantum Processor with Effective All-to-All Connectivity
Michael Renger, Jeroen Verjauw, Nicola Wurz +62
In this work we introduce a superconducting quantum processor architecture that uses a transmission-line resonator to implement effective all-to-all connectivity between six transm…
On-Premises Superconducting Quantum Computer for Education and Research
Jami Rönkkö, Olli Ahonen, Ville Bergholm +13
With a growing interest in quantum technology globally, there is an increasing need for accessing relevant physical systems for education and research. In this paper we introduce a…
Transmon-qubit readout using in-situ bifurcation amplification in the mesoscopic regime
R. Dassonneville, T. Ramos, V. Milchakov +8
We demonstrate a transmon qubit readout based on the nonlinear response to a drive of polaritonic meters in-situ coupled to the qubit. Inside a 3D readout cavity, we place a transm…
Observation of quantum many-body effects due to zero point fluctuations in superconducting circuits
Sebastien Leger, Javier Puertas-Martinez, Karthik Bharadwaj +11
Electromagnetic fields possess zero point fluctuations (ZPF) which lead to observable effects such as the Lamb shift and the Casimir effect. In the traditional quantum optics domai…
Fabrication and characterization of aluminum SQUID transmission lines
Luca Planat, Ekaterina Al-Tavil, Javier Puertas Martinez +10
We report on the fabrication and characterization of 50 Ohms, flux-tunable, low-loss, SQUID-based transmission lines. The fabrication process relies on the deposition of a thin die…
