Observation of quantum interference between separated mechanical oscillator wavepackets
D. Kienzler, C. Flühmann, V. Negnevitsky +4
The ability of matter to be superposed at two different locations while being intrinsically connected by a quantum phase is among the most counterintuitive predictions of quantum p…

Time-dependent Hamiltonian estimation for Doppler velocimetry of trapped ions
L. E. de Clercq, R. Oswald, C. Flühmann +7
The time evolution of a closed quantum system is connected to its Hamiltonian through Schroedinger's equation. The ability to estimate the Hamiltonian is critical to our understand…

Parallel transport quantum logic gates with trapped ions
Ludwig E. de Clercq, Hsiang-Yu Lo, Matteo Marinelli +6
We demonstrate single-qubit operations by transporting a beryllium ion with a controlled velocity through a stationary laser beam. We use these to perform coherent sequences of qua…
