Thank you for visiting my website.

My name is Minho Kwon.

I am a postdoc in the group of Sebastian Will at Columbia University. 

I received my Ph.D. in Physics at the University of Wisconsin-Madison in the group of Mark Saffman, where we explored interesting dynamics of Rydberg atoms in the context of

quantum information and computation. 


|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.

Gave a talk at the Midwest Cold Atom Workshop (MCAW) 2019 at Northwestern University.




|14 W @ 770 nm SHG paper, Sep. 3rd, 2019

Our work on high power SHG has been posted on arXiv:1909.00106. We use an LBO crystal with an enhancement cavity to achieve high conversion efficiency.

Update Nov. 11th: Accepted to Optics Letters

Update Jan. 6th: Published, Opt. Lett. 45, 339-342 (2020) 




|Rydberg gate paper, Aug. 19th, 2019

Trent and Mark posted our work on two-qubit Rydberg gates in a 2-dim atomic array on arXiv:1908.06103. Complementary work from Harvard is on PRL 123,170503.

Update Nov. 8th: Accepted to PRL
