Quantum computer based on shuttling trapped ions

Pino et al.3 report the construction and operation of a prototype microchip-based, trapped-ion quantum computer that incorporates a promising architecture based on ion shuttling. In principle, a single quantum-computing module built according to the quantum-CCD design could hold hundreds or even thousands of usable qubits. Pino and colleagues’ paper describes the realization of a prototype microchip-based, trapped-ion quantum computer. However, there have been few comprehensive demonstrations of quantum-computing architectures capable of being scaled up to thousands of quantum bits (qubits). Because of its similarity to microchips known as charge-coupled device (CCD) arrays, this design has been termed the quantum-CCD architecture5,6. In a computing platform known as the quantum charge-coupled device (CCD) architecture, atomic ions hover above the surface of a microchip. The concept of quantum computing relies on the strange phenomena of quantum physics, the counter-intuitive predictions of which Albert Einstein referred to as spooky.
