A microchip-based quantum computer has been built incorporating an architecture in which calculations are carried out by shuttling atomic ions (with excellent performance and potential scaling up).

"Trapped ions have delivered world records in reducing errors that occur in the operation of quantum gates used to carry out calculations, but many demonstrations have not been chip-based or have been accomplished with only 2–15 qubits."
"New prototype microchip-based, trapped-ion quantum computer [is] somewhat reminiscent of the Pac-Man video game: ions hover above the surface of the microchip and are moved along tracks by the adjustment of voltages applied to electrodes located on the chip surface."
"The device has a quantum volume of 64, which means that it can do generalized computations using up to 6 qubits. In principle, a single quantum-computing module built according to the quantum-CCD design could hold hundreds or even thousands of usable qubits."
