British Science Fesival
As part of the British Science Fesival we exhibit a walk-in quantum computer model, 5-9 September, 11am until 3.30pm, on Sussex campus. Winfried Hensinger will also give a public lecture on Tuesday September 5th, 2017 14:30 A2, Asa Briggs Arts, University of Sussex campus. Click here for more information.
Blueprint for a microwave trapped-ion quantum computer
We unveil the first industrial blueprint on how to build a large-scale quantum computer. The work features a new invention permitting actual quantum bits to be transmitted between individual quantum computing modules in order to obtain a fully modular large-scale machine. The work is published in Science Advances. (more…)
Trapped-ion quantum logic with global radiation fields
We describe a new approach for trapped-ion quantum computing based on the application of global radiation fields and voltages applied to individual gate zones. Using this technique we demonstrate a two-qubit quantum gate producing a maximally entangled state with fidelity close to the fault-tolerant threshold. This quantum gate also constitutes a simple-to-implement tool for quantum metrology, sensing and simulation. (more…)

Ground-state cooling of a trapped ion using long-wavelength radiation
We demonstrate ground-state cooling of a trapped ion using long-wavelength radiation. This is a powerful tool for the implementation of quantum operations, where long-wavelength radiation instead of lasers is used for motional quantum state engineering.
