Journal ArticleDOI

Torsten Gaebel,M. Domhan,I. Popa,Christoffer Wittmann,Philipp Neumann,Fedor Jelezko,James R. Rabeau,N. Stavrias,Andrew D. Greentree,Steven Prawer,Jan Meijer,Jason Twamley,Philip R. Hemmer,Joerg Wrachtrup +13 more
TL;DR: In this article, a single pair of strongly coupled spins in diamond, associated with a nitrogen-vacancy defect and a nitrogen atom, respectively, can be optically initialized and read out at room temperature.
Journal ArticleDOI
Quantum register based on coupled electron spins in a room-temperature solid.
Philipp Neumann,Roman Kolesov,Boris Naydenov,J. Beck,F. Rempp,Matthias Steiner,Vincent Jacques,Gopalakrishnan Balasubramanian,Matthew Markham,Daniel J. Twitchen,S. Pezzagna,Jan Meijer,Jason Twamley,Fedor Jelezko,Jörg Wrachtrup +14 more
TL;DR: In this article, coherent coupling between two electron spins separated by almost 10 nm has been demonstrated, which might enable the construction of a network of connected quantum registers at room temperature, at this distance, the spins can be addressed individually.
Journal ArticleDOI
Observation and control of blinking nitrogen-vacancy centres in discrete nanodiamonds
Carlo Bradac,Torsten Gaebel,N. Naidoo,Matthew Sellars,Jason Twamley,Louise J. Brown,Amanda S. Barnard,Taras Plakhotnik,Andrei V. Zvyagin,James R. Rabeau +9 more
TL;DR: The first direct observation of nitrogen-vacancy centres in discrete 5-nm nanodiamonds at room temperature is reported, including evidence for intermittency in the luminescence (blinking) from the nanod diamonds, and it is shown that it is possible to control this blinking by modifying the surface of the nanODiamonds.
Journal ArticleDOI
High-dynamic-range magnetometry with a single nuclear spin in diamond
G. Waldherr,J. Beck,Philipp Neumann,Ressa S. Said,Ressa S. Said,M. Nitsche,Matthew Markham,Daniel James Twitchen,Jason Twamley,Fedor Jelezko,Fedor Jelezko,Jörg Wrachtrup +11 more
TL;DR: A quantum phase estimation algorithm on a single nuclear spin in diamond is implemented to combine both high sensitivity and high dynamic range and achieves a scaling of the precision with time to T(-0.85), which improves the sensitivity and dynamic range.
Journal ArticleDOI
Two-photon quantum walks in an elliptical direct-write waveguide array
J. O. Owens,Matthew A. Broome,D. N. Biggerstaff,M. E. Goggin,M. E. Goggin,Alessandro Fedrizzi,Trond Linjordet,Martin Ams,Graham D. Marshall,Jason Twamley,Michael J. Withford,Andrew White +11 more
TL;DR: In this article, the evolution of two-photon states in an elliptic array of waveguides was studied using coherent light tomography and the results were used to predict distinct differences between temporally indistinguishable and distinguishable twophoton inputs.
