Proceedings ArticleDOI
Gate reflectometry for probing charge and spin states in linear Si MOS split-gate arrays
Louis Hutin,Theodor Lundberg,Anasua Chatterjee,A. Crippa,Jing Li,Romain Maurand,Xavier Jehl,M. Sanquer,M. F. Gonzalez-Zalba,Ferdinand Kuemmeth,Yann-Michel Niquet,Benoit Bertrand,S. De Franceschi,Matias Urdampilleta,Tristan Meunier,M. Vinet,E. Chanrion,H. Bohuslavskyi,Fabio Ansaloni,Tsung-Yeh Yang,J. Michniewicz,D. J. Niegemann,C. Spence +22 more
TL;DR: In this article, the authors implemented two different gate reflectometry-based readout schemes to either probe spin-dependent charge movements by a coupled electrometer with single-shot precision, or directly sense a spindependent quantum capacitance.
Journal ArticleDOI
A Spin Quintet in a Silicon Double Quantum Dot: Spin Blockade and Relaxation
Theodor Lundberg,Jing Li,Louis Hutin,Benoit Bertrand,David J. Ibberson,Chang-Min Lee,David J. Niegemann,Matias Urdampilleta,N. A. Stelmashenko,Tristan Meunier,Jason W. A. Robinson,Lisa Ibberson,Maud Vinet,Yann-Michel Niquet,M. Fernando Gonzalez-Zalba +14 more
TL;DR: In this article, the authors present spin blockade physics in a tunnel-coupled silicon double quantum dot defined in the corners of a split-gate transistor and report successive steps of spin blockade and spin blockade lifting involving spin states with total spin angular momentum up to 3.
Journal ArticleDOI
Large Dispersive Interaction between a CMOS Double Quantum Dot and Microwave Photons
David J. Ibberson,David J. Ibberson,Theodor Lundberg,Theodor Lundberg,J. A. Haigh,Louis Hutin,Benoit Bertrand,Sylvain Barraud,Chang-Min Lee,N. A. Stelmashenko,Giovanni A. Oakes,Giovanni A. Oakes,Laurence Cochrane,Laurence Cochrane,Jason W. A. Robinson,Maud Vinet,M. Fernando Gonzalez-Zalba,Lisa Ibberson +17 more
TL;DR: In this article, a dual-chip architecture is presented for gate dispersive readout of charge states in quantum electronic devices, which outperforms previous fully-integrated systems and may facilitate scaling of spin-qubits.

Spin Quintet in a Silicon Double Quantum Dot: Spin Blockade and Relaxation
Theodor Lundberg,Theodor Lundberg,Jing Li,Louis Hutin,Benoit Bertrand,David J. Ibberson,David J. Ibberson,Chang-Min Lee,David J. Niegemann,Matias Urdampilleta,N. A. Stelmashenko,Tristan Meunier,Jason W. A. Robinson,Lisa Ibberson,Maud Vinet,Yann-Michel Niquet,M. Fernando Gonzalez-Zalba +16 more
TL;DR: A new method for identifying spin arrangements leads to the discovery of a novel spin system in a pair of silicon quantum dots, a promising testbed for studying high-spin systems.
Journal ArticleDOI

Giovanni A. Oakes,Virginia N. Ciriano-Tejel,David F. Wise,Michael A. Fogarty,Theodor Lundberg,C. Lain'e,Simon Schaal,F. L. B. Martins,David Ibberson,Louis Hutin,Benoit Bertrand,N. A. Stelmashenko,Jeffrey A. Robinson,Lisa Ibberson,A.E. Hashim,Irfan Siddiqi,A. Lee,Maud Vinet,John J. L. Morton,M. F. Gonzalez-Zalba +19 more
TL;DR: In this article , the authors present two complementary demonstrations of fast high-fidelity single-shot readout of spins in silicon quantum dots using a compact, dispersive charge sensor: a radio-frequency single-electron box.
