Quantum imaging of spin states in optical lattices
James Douglas, Keith Burnett
We investigate imaging of the spatial spin distribution of atoms in optical lattices using non-resonant light scattering. We demonstrate how scattering spatially correlated light f…
Quantum key distribution system in standard telecommunications fiber using a short wavelength single-photon source
R. J. Collins, P. J. Clarke, V. Fernandez +8
A demonstration of the principles of quantum key distribution is performed using a single-photon source in a proof of concept test-bed over a distance of 2 km in standard telecommu…
General optimality of the Heisenberg limit for quantum metrology
Marcin Zwierz, Carlos A. Perez-Delgado, Pieter Kok
Quantum metrology promises improved sensitivity in parameter estimation over classical procedures. However, there is an extensive debate over the question how the sensitivity scale…
Geometric derivation of the quantum speed limit
Philip J. Jones, Pieter Kok
The Mandelstam-Tamm and Margolus-Levitin inequalities play an important role in the study of quantum mechanical processes in Nature, since they provide general limits on the speed…
