SC-1 Etching of Niobium and Titanium Nitride Thin Films
Adrián Gutiérrez-Cruz, K. A. C. Rathnathilaka, Jani M. Taskinen +6
Dry etching techniques, ubiquitous in microelectronics fabrication, often result in challenging levels of undesired collateral plasma-induced damage. In this work, we demonstrate a…
Multiplexed microwave resonators by frequency comb spectroscopy
Angelo Greco, Jukka-Pekka Kaikkonen, Luca Chirolli +4
Coplanar waveguide resonators are central to the thriving field of circuit quantum electrodynamics. Recently, we have demonstrated the generation of a broadband microwave-frequency…
Native-oxide-passivated trilayer junctions for superconducting qubits
Pankaj Sethi, Om Prakash, Jukka-Pekka Kaikkonen +15
Superconducting qubits in today's quantum processing units are typically fabricated with angle-evaporated aluminum--aluminum-oxide--aluminum Josephson junctions. However, there is…
Wafer-scale CMOS-compatible graphene Josephson field-effect transistors
Andrey A. Generalov, Klaara L. Viisanen, Jorden Senior +5
Electrostatically tunable Josephson field-effect transistors (JoFETs) are one of the most desired building blocks of quantum electronics. JoFET applications range from parametric a…
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…
Superconductivity from a melted insulator
S. Mukhopadhyay, J. Senior, J. Saez-Mollejo +4
Quantum phase transitions typically result in a broadened critical or crossover region at nonzero temperature. Josephson arrays are a model of this phenomenon, exhibiting a superco…
Detecting induced pairing at the Al-InAs interface with a quantum microwave circuit
D. Phan, J. Senior, A. Ghazaryan +5
Superconductor-semiconductor hybrid devices are at the heart of several proposed approaches to quantum information processing, but their basic properties remain to be understood. W…
Heat rectification via a superconducting artificial atom
Jorden Senior, Azat Gubaydullin, Bayan Karimi +3
In miniaturising electrical devices down to nanoscales, heat transfer has turned into a serious obstacle but also potential resource for future developments, both for conventional…
Utilization of the Superconducting Transition for Characterizing Low-Quality-Factor Superconducting Resonators
Yu-Cheng Chang, Bayan Karimi, Jorden Senior +5
Characterizing superconducting microwave resonators with highly dissipative elements is a technical challenge, but a requirement for implementing and understanding the operation of…
Tunable photonic heat transport in a quantum heat valve
Alberto Ronzani, Bayan Karimi, Jorden Senior +4
Quantum thermodynamics is emerging both as a topic of fundamental research and as means to understand and potentially improve the performance of quantum devices. A prominent platfo…
Multiplexing Superconducting Qubit Circuit for Single Microwave Photon Generation
R E George, J Senior, O-P Saira +4
We report on a device that integrates eight superconducting transmon qubits in lambda/4 superconducting coplanar waveguide resonators fed from a common feedline. Using this multipl…
Direct measurements of the extraordinary optical momentum and transverse spin-dependent force using a nano-cantilever
M. Antognozzi, C. R. Bermingham, R. L. Harniman +8
Known since Kepler's observation that a comet's tail is oriented away from the sun, radiation pressure stimulated remarkable discoveries in electromagnetism, quantum physics and re…
