Programmable and scalable radio-frequency pulse sequence generator for multi-qubit quantum information experiments
Ben Keitch, Vlad Negnevitsky, Weida Zhang
We present a versatile rf pulse control system that has been designed for multi-qubit quantum experiments. One instrument can be scaled to provide 32 channels of rf between 10 - 45…
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…
Fast quantum control and light-matter interactions at the 10,000 quanta level
J. Alonso, F. M. Leupold, Z. U. Soler +5
Fast control of quantum systems is essential in order to make use of quantum properties before they are degraded by decoherence. This is important for quantum-enhanced information…
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…
An ion trap built with photonic crystal fibre technology
F. Lindenfelser, B. Keitch, D. Kienzler +5
We demonstrate a surface-electrode ion trap fabricated using techniques transferred from the manufacture of photonic-crystal fibres. This provides a relatively straightforward rout…
Spin-motion entanglement and state diagnosis with squeezed oscillator wavepackets
Hsiang-Yu Lo, Daniel Kienzler, Ludwig de Clercq +4
Mesoscopic superpositions of distinguishable coherent states provide an analog to the Schrödinger's cat thought experiment. For mechanical oscillators these have primarily been rea…
