Abstract

I will discuss progress at NIST towards scaling up ion-trap quantum information processing. This will include developments in segmented trap microfabrication, sympathetic cooling, and new methods for reducing the complexity of control fields.

Scalable quantum computing architecture with mixed species ion chains

John Wright, Carolyn Auchter, Chen-Kuan Chou +5 more

We describe our work on trapping, cooling and detecting mixed ion species for a scalable ion trap quantum information processing architecture. These mixed species chains in linear RF traps may help solve several problems with scaling ion trap quantum computation to large numbers of qubits. Initial temperature measurements of linear Coulomb crystals containing barium and ytterbium ions indicate that the mass difference does not significantly impede sympathetic cooling of normal modes that couple well to the coolant ions (Ba in our case). Average motional occupation numbers are estimated to be 10 to 20 quanta per mode for these well cooled modes for chains with small numbers of ions, consistent with the Doppler limit temperature. For normal modes that do not couple significantly to the coolant atoms, the occupation numbers are significantly higher, of order several thousand. Strategies for better cooling of these modes are discussed. Further, we are working to implement these techniques in microfabricated surface traps in order to exercise greater control over ion chain ordering and positioning.

Quantum information processing (QIP) has become a hot research topic as evidenced by S. Haroche and D. J. Wineland receiving the Nobel Prize in Physics in 2012. Various MEMS-based microfabrication methods will be a key enabling technology in implementing novel and scalable ion traps for QIP. This paper provides a brief introduction of ion trap devices, and reviews ion traps made using conventional precision machining as well as MEMS-based microfabrication. Then, microfabrication methods for ion traps are explained in detail. Finally, current research issues in microfabricated ion traps are presented. The QIP renders significant new challenges for MEMS, as various QIP technologies are being developed for secure encrypted communication and complex computing applications.

Silicon microfabricated linear segmented ion traps for quantum technologies

Kaushal Choonee, G. Wilpers, Alastair G. Sinclair

This paper describes a microfabricated linear segmented RF Paul trap for atomic quantum technologies. The microtrap geometry, initially demonstrated in [1], has been augmented and includes a linear array of trapping segments. Trapping of individual and strings of 88Sr+ ions is demonstrated. The fabrication process has been optimized such that for 80 % of the fabricated devices, the achieved geometry is within ± 5 μm (or ± 3 %) of a prescribed design. This is critical for scalable quantum information processing, where arrays of traps with consistent parameters are required.
