The first member of Nelly Ng' group on #quantum information at NTU was Jeongrak Son and he recently became her first graduated PhD student. Together they have very unique collegial dynamic and camaraderie, there is some kindness in it that is hard to pin down […] [Original post on mathstodon.xyz]

In work published in @physrevlett.bsky.social, CQT researchers and collaborators describe how a math technique first introduced 35 years ago can be repurposed to help quantum computers find many-body ground states. Our story: www.cqt.sg/highlight/20... The paper: journals.aps.org/prl/abstract...

Double-bracket quantum imaginary-time evolution - a #quantum algorithm for implementing ground-states of local Hamiltonians is now published at PRL. https://journals.aps.org/prl/abstract/10.1103/rw81-k8vk and the equivalent freely accessible preprint is here https://arxiv.org/abs/2412.04554 […]

Two double-bracket works just jumped out🧑‍🍳🧑‍🍳— (1) PRL journals.aps.org/prl/abstract... With coauthors @marekgluza.mathstodon.xyz.ap.brid.gy @perp-waterfall.bsky.social @nellynghy.bsky.social @qzoeholmes.bsky.social, Yudai Suzuki, René Zander, Raphael Seidel

Last week I defended my thesis "Quantum Qomrades: Catalysts in Resource Theories and Memories in Dynamic Programming". This journey was possible thanks to all my human comrades, especially my amazing adviser @nellynghy.bsky.social !

Our Grover preprint just popped up! (with Yudai Suzuki, @qzoeholmes.bsky.social, @marekgluza.mathstodon.xyz.ap.brid.gy, @nellynghy.bsky.social, @perp-waterfall.bsky.social) Turns out… Grover's algorithm is secretly moonlighting as a first-order approximation to the imaginary time evolution!
