12 Nov, 2020 - Nik awarded with best presentation award!
University of Waterloo and University of Strathclyde, Glasgow, UK hosted their first virtual research colloquium on 12 Nov, 2020. Nikolay presented a talk on behalf of the QuantumION project, focusing on our design for individual addressing of Barium qubits.
His talk was judged to be the best UW presentation of the day! Congrats, Nik!
20 Oct, 2020 - Rajibul honoured with President’s Excellence in Research award!
Rajibul received a President’s Excellence in Research award from the President and Vice-Chancellor of University of Waterloo in recognition of an Early Researcher Award from the Government of Ontario.
14 Aug, 2020 - Manas defends his MSc thesis!
Dr. Manas Sajjan defends his MSc thesis online! His MSc work included both theoretical and experimental aspects. On the theoretical side, Manas investigated the role of optical tweezer potentials on ions confined in a radio-frequency (RF) trap. Optical tweezers would allow for local control of the confining potential, which can be used for investigating quantum thermodynamics. On the experimental side, Manas was part of the team that built our four-rod trap. He fabricated the electrodes, built the RF resonator which powers them, and worked on optics.
Congrats, Manas!
16 July 2020 - Building a quantum simulator
Here is a feature of our lab by IQC. The students look very happy playing with ions!
1-5 Jun 2020 - DAMOP
DAMOP (online) talks presented by Chung-You (Gilbert) Shih on individual addressing of ions and Dr. Matt Day on QuantumION. Posters were presented by Nikolay Videnov and Sainath Motlakunta.
12 May 2020 - TUCAN meeting
Nikhil Kotibhaskar presents a talk at (virtual) TUCAN (Toronto Area Ultracold Atom Network), organized by University of Toronto. This is the third edition of the annual meeting. McMaster University and University of Waterloo hosted the meeting in the previous two years.
21 Jan 2020 - Paper on Machine learning published
“Machine learning design of a trapped-ion quantum spin simulator” is published in Quantum Science and Technology 5 (2020) 024001, ( arXiv.1910.02496). We numerically demonstrate that a machine learning neural network can be used to efficiently solve a non-linear inversion problem in an analog trapped-ion quantum simulator. The method generates experimental control parameters (such as laser intensities on each ions) needed to program a quantum simulator, in particular, to engineer an arbitrary spin lattice geometry in one, two, and three dimensions using a linear chain of ions!
17 Dec 2019 - A review on trapped-ion quantum simulation!
Here is a pre-print version of a review article on quantum simulation with trapped ions. The article focuses on analog spin simulation, and discusses the progress in this field so far. (arxiv.1912.07845).
8 Oct 2019 - Machine learning for a quantum simulator!
Our manuscript “Machine learning design of a trapped-ion quantum spin simulator” is on arXiv.1910.02496. We demonstrate that a machine learning neural network can be used to efficiently engineer an arbitrary spin-spin interaction graph on an analog quantum simulator.

13 Aug 2019 - Yb+ ions
Here’s a picture of eight laser-cooled Ytterbium (174 isotope) ions in a linear chain! The image was taken using an off-the-shelf Thorlabs 0.1 NA objective and a cheap (~$300) CMOS camera. The ions are approximately 8 microns apart. Read more on the Physics and Astronomy webpage.
