Cryogenic microwave link for quantum local area networks
W. K. Yam, M. Renger, S. Gandorfer +16
Scalable quantum information processing with superconducting circuits is expected to advance from individual processors located in single dilution refrigerators to more powerful di…
Effect of ion irradiation on superconducting thin films
Katja Kohopää, Alberto Ronzani, Robab Najafi Jabdaraghi +8
We demonstrate ion irradiation by argon or gallium as a wafer-scale post-processing method to increase disorder in superconducting thin films. We study several widely used supercon…
Broadband continuous variable entanglement generation using Kerr-free Josephson metamaterial
Michael Perelshtein, Kirill Petrovnin, Visa Vesterinen +13
Entangled microwave photons form a fundamental resource for quantum information processing and sensing with continuous variables. We use a low-loss Josephson metamaterial comprisin…
Spatial and energy resolution of electronic states by shot noise
E. S. Tikhonov, A. O. Denisov, S. U. Piatrusha +5
Shot noise measurements are widely used for the characterization of nonequilibrium configurations in electronic conductors. The recently introduced quantum tomography approach was…
Magnetometry with low resistance proximity Josephson junction
R. N. Jabdaraghi, J. T. Peltonen, D. S. Golubev +1
We characterize a niobium-based superconducting quantum interference proximity transistor (Nb-SQUIPT) built upon a Nb-Cu-Nb SNS weak link. The Nb-SQUIPT and SNS devices are fabrica…
Noise of a superconducting magnetic flux sensor based on a proximity Josephson junction
R. N. Jabdaraghi, D. S. Golubev, J. P. Pekola +1
We demonstrate simultaneous measurements of DC transport properties and flux noise of a hybrid superconducting magnetometer based on the proximity effect (superconducting quantum i…
Non-hysteretic superconducting quantum interference proximity transistor with enhanced responsivity
Robab Najafi Jabdaraghi, Matthias Meschke, Jukka Pekola
This letter presents fabrication and characterization of an optimized SQUIPT (superconducting quantum interference proximity transistor). The present device, characterized with red…
