Journal ArticleDOI
Will Spin-Relaxation Times in Molecular Magnets Permit Quantum Information Processing?
Arzhang Ardavan,Olivier Rival,John J. L. Morton,Stephen J. Blundell,Alexei M. Tyryshkin,Grigore A. Timco,Richard E. P. Winpenny +6 more
TL;DR: In this article, the intrinsic spin-lattice and phase-coherence relaxation times in molecular nanomagnets were reported for the first time using pulsed electron-spin resonance.
Journal ArticleDOI
Solid-state quantum memory using the 31 P nuclear spin
John J. L. Morton,Alexei M. Tyryshkin,Richard M. Brown,Shyam Shankar,Brendon W. Lovett,Arzhang Ardavan,Thomas Schenkel,Eugene E. Haller,Eugene E. Haller,Joel W. Ager,Stephen Aplin Lyon +10 more
TL;DR: In this article, the authors demonstrate coherent storage and readout of information between electron-spin processing elements and memory elements based on a nuclear spin, using a combination of microwave and radio-frequency pulses applied to 31P donors in an isotopically pure 28Si crystal.
Journal ArticleDOI
Electron paramagnetic resonance of individual atoms on a surface
Susanne Baumann,Susanne Baumann,William Paul,Taeyoung Choi,Christopher P. Lutz,Arzhang Ardavan,Andreas J. Heinrich +6 more
TL;DR: This work used a spin-polarized scanning tunneling microscope tip to measure EPR spectra of single iron atoms adsorbed on a magnesium oxide surface at cryogenic temperatures, and drove the spin resonance with an oscillating electric field between tip and sample.

Journal ArticleDOI
Magnetic Field Sensing Beyond the Standard Quantum Limit Using 10-Spin NOON States
Jonathan A. Jones,Steven D. Karlen,Joseph F. Fitzsimons,Joseph F. Fitzsimons,Arzhang Ardavan,Simon C. Benjamin,Simon C. Benjamin,G. Andrew D. Briggs,John J. L. Morton +8 more
TL;DR: Compared the magnetic field sensitivity of a classical (unentangled) system with that of a 10-qubit entangled state, realized by nuclei in a highly symmetric molecule, and observed a 9.4-fold quantum enhancement in the sensitivity to an applied field for the entangled system.
