Prof John J. L. Morton is Professor of Nanoelectronics & Nanophotonics at UCL, and leads the Quantum Spin Dynamics research group. He has a played a key role in the development of donor spin qubits in silicon.

He first showed how the nuclear spin of P donors could be used as a quantum memory for electron spins [Nature 455 1085 (2008)], and demonstrated the first on-demand quantum entanglement between electron and nuclear spins in an ensemble, using P donors in Si [Nature 470 69 (2011)]. More recently, he and his collaborators have shown that donor spins in silicon have the longest coherence times of any solid state systems: 3 seconds for the electron spin [Nature Nanotechnology 8 561 (2013)], 3 minutes for the neutral donor nuclear spin [Science 336 6086 (2012)] and up to 3 hours for the ionised donor nuclear spin [Science 342 830 (2013)].

Morton has also shown how Stark shifts of donors can be used to perform conditional control on nuclear spins, using electric fields [Phys Rev Lett 113 157601 (2014)]. Most recently, working together with collaborators on this proposal, namely CEA and Hitachi Cambridge Laboratory, Morton’s team has shown that how donors and dots can be coupled to form singlet and triplet states in a finFET structure, showing spin blockade [Urdampilleta et al., arXiv:1503.01049 (2015)].

Morton’s awards include the Nicholas Kurti European Science prize (2008) and the Institute of Physics Moseley Medal (2013) in experimental physics. He has published over 80 papers in the past 10 years with over 3700 citations and has an h-index of 29. He is active in the public engagement of science, including public exhibitions, documentaries, radio broadcasts and popular articles on quantum science and technology.
