Abstract

Practical-scale quantum computing using trapped atomic ions requires non-conventional integration technologies in mechanical and optical domains. We present the design and operation of our system where MEMS technology provides critical enabling components.

Ion trap quantum computing using integrated photonics

Karan K. Mehta, Alfredo Ricci Vásquez, Carmelo Mordini +6 more

Atomic ions controlled by laser light are among the leading candidates for large scale quantum computing. However operational systems today require vast scaling to reach levels capable of useful computational tasks. The integration of light delivery will be an essential component of this for the trapped-ion approach. I will describe results in which the use of photonics integrated into ion trap chips has allowed us to perform high fidelity two-qubit gates, which are an essential building block for quantum computers. These systems have now been extended to the operation of multiple trap zones, and the creation of novel optical fields for ion trap control while a new generation of chips allowing integration of all required wavelengths as well as optimised light delivery offers further enhancements in performance and scaling.

Trapped atomic ions manipulated by laser beams is a leading candidate to construct scalable and practical quantum computers. Fully programmable quantum computers have been constructed using this technology, offering the highest performance quantum computing in commercial setting. Controlling atomic qubits with lasers is at the heart of constructing reliable trapped ion quantum computers.

Application of OMEMS technology in trapped ion quantum computing

Scalability is one of the main challenges of trapped ion based quantum computation, partly limited by the ability to manipulate the increasing number of quantum bits (qubits). For individual addressing of qubits, microelectromechanical systems (MEMS) technology allows one to design movable micromirrors to focus laser beams on individual ions and steer the focal point in two dimensions. This system is able to scale to multiple beams, has switching speeds comparable to typical single qubit gate times, and has negligible crosstalk on neighboring ions.

Trapped-ion quantum computing: Progress and challenges

Colin Bruzewicz, John Chiaverini, Robert McConnell +1 more

Trapped ions are among the most promising systems for practical quantum computing (QC). The basic requirements for universal QC have all been demonstrated with ions, and quantum algorithms using few-ion-qubit systems have been implemented. We review the state of the field, covering the basics of how trapped ions are used for QC and their strengths and limitations as qubits. In addition, we discuss what is being done, and what may be required, to increase the scale of trapped ion quantum computers while mitigating decoherence and control errors. Finally, we explore the outlook for trapped-ion QC. In particular, we discuss near-term applications, considerations impacting the design of future systems of trapped ions, and experiments and demonstrations that may further inform these considerations.
