Scalable High-Performance Fluxonium Quantum Processor

Posted by klaurent Berkeley

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Long B. Nguyen, Gerwin Koolstra, Yosep Kim, Alexis Morvan, Trevor Chistolini | Summary: The technological development of hardware heading toward universal fault-tolerant quantum computation requires a large-scale processing unit with high performance. While fluxonium qubits are promising with high coherence and large anharmonicity, their scalability has not […]

Van der Waals pi Josephson junctions

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Kaifei Kang, Helmuth Berger, Kenji Watanabe, Takashi Taniguchi, Laszlo Forro | Summary: Proximity-induced superconductivity in a ferromagnet can induce Cooper pairs with a finite center-of-mass momentum. The resultant spatially modulated superconducting order parameter is able to stabilize Josephson junctions (JJs) with pi phase difference in superconductor-ferromagnet heterostructures […]
