Summary
Trapped ions are one of the most advanced technologies for quantum computing, offering multi-qubit control in a universal quantum computing architecture and the ability to perform calculations with unprecedented precision. In this project we construct a shared trapped-ion quantum computing platform, QuantumIon, that will enable a broader and interdisciplinary scientific community to access an advanced quantum computing platform, thereby accelerating the discovery of new methods and applications of quantum computing.To this end, we build appropriate control electronics, test the suitability of our chosen barium isotope for multi-qubit operations, and construct a 10-qubit processor and benchmark its performance in collaboration with Joseph Emerson. We then demonstrate quantum algorithms from a variety of applications areas: quantum simulation by Rajibul Islam in collaboration with Christine Muschik, quantum error correction in collaboration with Raymond Laflamme, and characterization of multi-level qudits by Crystal Senko in collaboration with Joseph Emerson and Joel Wallman. The QuantumIon will make trapped ion hardware more automated and accessible to users, opening up a range of new experiments from quantum optics to multi-level qudit manipulation to quantum error correction.

Zero-Dimensional Quantum Materials for the Next Generation of Highly-Selective Chemical Sensors
Summary Heavy metals are a major public health concern and their on-site detection in water supplies is not well served by existing lab techniques. We develop a new multi-modal platform comprising functionalized quantum dots of two-dimensional materials (2D-QDs) for the sensing of four highly-toxic heavy metal pollutants (arsenic, cadmium, lead and mercury). The zero-dimensional […]

Quantum State Tomography with Machine Learning
Summary An important challenge in building a quantum computer is quantifying the level of control obtained in the preparation of a quantum state. The state of a quantum device is characterized from experimental measurements, using a procedure known as tomography. Exact tomography requires a vast amount of computer resources, making it prohibitive for quantum […]
