Nonlocal Josephson coupling and current redistribution in a large-area graphene multiterminal Josephson junction
Luojia Zhang, Kushagra Aggarwal, Jay D. Sau +4
Multiterminal Josephson junctions (MTJJs) extend conventional two-terminal Josephson physics to devices defined by multiple superconducting phases, where rich phenomena have been p…
Fabrication-free assessment of microwave losses in germanium-based dielectrics and superconductors
Haoran Lu, Kushagra Aggarwal, Xiangqin Wang +10
We present a flip-chip-based sensing scheme to measure effective microwave losses associated with target materials for quantum technologies, without requiring any device fabricatio…
Sources of nonlinearity in the response of a driven nano-electromechanical resonator
Sofia Sevitz, Kushagra Aggarwal, Jorge Tabanera-Bravo +9
Nanoelectromechanical resonators provide an ideal platform for investigating the interplay between electron transport and nonlinear mechanical motion. Externally driven suspended c…
Low barrier ZrO-based Josephson junctions
Jaehong Choi, Maciej Olszewski, Luojia Zhang +8
The Josephson junction is a crucial element in superconducting devices, and niobium is a promising candidate for the superconducting material due to its large energy gap relative t…
Rapid optimal work extraction from a quantum-dot information engine
Kushagra Aggarwal, Alberto Rolandi, Yikai Yang +8
The conversion of thermal energy into work is usually more efficient in the slow-driving regime, where the power output is vanishingly small. Efficient work extraction for fast dri…
Coupling a single spin to high-frequency motion
Federico Fedele, Federico Cerisola, Lea Bresque +12
Coupling a single spin to high-frequency mechanical motion is a fundamental bottleneck of applications such as quantum sensing, intermediate and long-distance spin-spin coupling, a…
Parity-conserving Cooper-pair transport and ideal superconducting diode in planar Germanium
Marco Valentini, Oliver Sagi, Levon Baghumyan +16
Superconductor/semiconductor hybrid devices have attracted increasing interest in the past years. Superconducting electronics aims to complement semiconductor technology, while hyb…
Stability of long-sustained oscillations induced by electron tunneling
Jorge Tabanera-Bravo, Florian Vigneau, Juliette Monsel +9
Self-oscillations are the result of an efficient mechanism generating periodic motion from a constant power source. In quantum devices, these oscillations may arise due to the inte…
Ultrastrong coupling between electron tunneling and mechanical motion
Florian Vigneau, Juliette Monsel, Jorge Tabanera +8
The ultrastrong coupling of single-electron tunneling and nanomechanical motion opens exciting opportunities to explore fundamental questions and develop new platforms for quantum…
Enhancement of Proximity Induced Superconductivity in a Planar Ge Hole Gas
Kushagra Aggarwal, Andrea Hofmann, Daniel Jirovec +9
Hole gases in planar germanium can have high mobilities in combination with strong spin-orbit interaction and electrically tunable g-factors, and are therefore emerging as a promis…
Development of On Board Computer for a Nanosatellite
Saurabh Raje, Abhishek Goel, Shubham Sharma +3
This paper describes the process of conceptualization, design, and testing of the Onboard Computer (OBC) Software for a 3U nanosatellite. The on-board computer of the satellite is…
