Quantum interference between two different locations. D. Kienzler et al. Phys. Rev. Lett. 116, 140402 (2016)
We observe directly the quantum interference between an atom superposed at two locations separated by 240 nm. We use a squeezed reconstruction to access large quantum states - the largest "Schrodinger's cats" observed to date.
Estimation of a general single-qubit Hamiltonian. L.E. de Clerq et al. Nature Comms. 7, 11218 (2016)
We devise a method for reconstructing any unknown Hamiltonian on a single spin, and demonstrate it using a single travelling ion.
Bang-bang control of trapped ion motion. J. Alonso et al. Nature Comms. 7, 11243 (2016)
Cryogenic CMOS electronics allows nano-second control of trapped-ion motional states
