Hi! Thank you for visiting my website.

My name is Minho Kwon. I am a postdoc in the group of Sebastian Will at Columbia University. We study quantum physics of atoms and lights. Particular system of interest is a programmable atomic tweezer array, where single atoms are trapped with reconfigurable optical tweezers. In this versatile platform we are addressing key questions below.

  • Can atoms collectively interact in a way so their collective quantum state live longer than their intrinsic lifetime?

Supported by NSF QII-TAQS grant, in collaboration with Asenjo-Garcia group and Yu group

  • Can we develop and implement quantum algorithms with real-world relevance in materials science, quantum chemistry and optimization?

Supported by NSF Convergence Accelerator grant, in collaboration with Brookhaven National Lab, CUNY, Flatiron Institute, Atom Computing, QuEra, IBM and Bloomberg. Press release.


Before I join Will Lab, I was in the group of Mark Saffman at University of Wisconsin-Madison. As a postdoc I contributed to Cesium atomic qubit array experiment, after finishing my Ph.D in Rubidium Rydberg super-atom project in the same group.

|Strontium 2D MOT, Sep. 28th, 2020

Atoms are great. Laser cooled atoms are even better. We saw the first signature of laser cooled Strontium in our chamber.

|First signal of Strontium, Sep. 1st, 2020

We observed the very first fluorescence from our home-built Strontium atom source only 2 month after the lab reopening.

|Started a new position at Columbia University, Mar. 9th, 2020

In the group of Sebastian Will, we are setting up Strontium tweezer (namely TweeSr project) experiments to explore how collective effects can be used to extend quantum coherence of atoms. This work is supported by NSF grant #1936359.
