The challenge for the platform + now is to maintain these high quality operations while expanding the system size beyond the ∼10-30 qubits that + are available in today’s devices. Currently we are near completion of the construction of our trapped ion quantum + computer that will incorporate multiple isotopes of barium as qubits/qudits. Barium has several favourable properties + that make it the ideal ion for QIP and the aim of our device in the near future is to develop this species into + the premiere ion for QIP. The device in the future is hoped to serve as a cloud based resource for the Waterloo + research community, fostering collaborations between algorithms, error correction and atomic physics researchers, + that is ultimately hoped to expedite the development of trapped ion QIP. This thesis discusses the robust optical + engineering that went into the construction of this trapped ion quantum computer. We describe the details of the + continuous wave optical subsystems used for ion initialization, cooling, and measurements of the quantum states, + including the imaging system used to collect ion fluorescence. In addition, this thesis discusses the unique individual + addressing system that we have designed and built for performing single and two-qubit gates based on Raman transitions. + With this system we attain a relative intensity crosstalk between neighbouring ions on the order of 1e−4. + This is comparable to the best currently available implementations but our system provides additional optical + frequency and phase control knobs that allow for more control over quantum simulation and computation experiments. + Finally we will discuss the trap, its associated electronics and the vacuum system that houses our ions and atomic source. diff --git a/content/publications/2024-Greenberg-microgram-ablation-paper.md b/content/publications/2024-Greenberg-microgram-ablation-paper.md new file mode 100644 index 00000000..07c70fcb --- /dev/null +++ b/content/publications/2024-Greenberg-microgram-ablation-paper.md @@ -0,0 +1,27 @@ +--- +title: "Microgram BaCl_2 Ablation Targets for Trapped Ion Experiments" +authors: [['Noah Greenberg'], ['Akbar Jahangiri Jozani','a2jahang'], ['Collin JC Epstein'], ['Xinghe Tan','Hawking Tan'], ['Rajibul Islam', 'krislam'], ['Crystal Senko']] +link: "" +journal: "" +volume: "" +issue: "" +date: 2024-02-06T00:00:00-00:00 +DOI: +draft: false +arXiv: "2402.06632" +tags: + - "QITI" +image: "images/publications/2024-Greenberg.png" +--- + +**Abstract:** Trapped ions for quantum information processing has been an area of intense study due to the extraordinarily high + fidelity operations that have been reported experimentally. Specifically, barium trapped ions have been shown to have + exceptional state-preparation and measurement (SPAM) fidelities. The 133Ba+ (I=1/2) isotope in particular is a promising candidate + for large-scale quantum computing experiments. However, a major pitfall with this isotope is that it is radioactive and + is thus generally used in microgram quantities to satisfy safety regulations. We describe a new method for creating microgram + barium chloride (BaCl_2) ablation targets for use in trapped ion experiments and compare our procedure to previous methods. We outline + two recipes for fabrication of ablation targets that increase the production of neutral atoms for isotope-selective loading of barium ions. + We show that heat-treatment of the ablation targets greatly increases the consistency at which neutral atoms can be produced + and we characterize the uniformity of these targets using trap-independent techniques such as energy dispersive x-ray spectroscopy (EDS) + and neutral fluorescence collection. Our comparison between fabrication techniques and demonstration of consistent neutral fluorescence + paves a path towards reliable loading of 133Ba+ in surface traps and opens opportunities for scalable quantum computing with this isotope. \ No newline at end of file diff --git a/static/images/publications/2024-Greenberg.png b/static/images/publications/2024-Greenberg.png new file mode 100644 index 00000000..76032ec3 Binary files /dev/null and b/static/images/publications/2024-Greenberg.png differ
