I’m hiring a strike-team of 10 intellectual ‘Swiss-knives’ who will forge #quantum technology advances with me at NTU Singapore. The team (5 PhD students, 3 Postdocs, 2 RAs) will operate along the following 3 profiles *Profile A.* From mathematics to algorithms: Geometrically designing quantum […]

Very cool long #chess puzzle, in fact an instructive position to figure out https://lichess.org/training/0ixxe

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]

Geometric cartoon of a useful class of quantum algorithms: At any stage of a #quantum computation the state of the quantum computer corresponds to a vector. Think of an arrow pointing from the center of a sphere to its surface. A quantum computing operation […] [Original post on mathstodon.xyz]

One pesky fineprint wipes out startups wildly more efficiently than any political circus you could name - failing to win clients cause startups to lose. Weak client pool invariably and sooner than later causes them to lose regardless idea, team, funding […] [Original post on mathstodon.xyz]

The Siam #Quantum Square is the new platform for quantum technologies in Thailand with goals to develop talents, foster excellence in research and consult i.e. be quantum-ready. Sounds all reasonable because wholesome people are organizing. Here in the photo […] [Original post on mathstodon.xyz]

More than 10 years ago, I have been shadowing Shantanav Chakraborty at a #quantum computing workshop. It was my first workshop ever and it was a big one - Matthias Troyer, Elham Kashefi, Peter Love and Barbara Terhal were among the speakers. Shantanav seemed […] [Original post on mathstodon.xyz]

This is a typical liquid sample which is used for NMR experiments. In the background you see a cross section of a typical NMR setup. The sample enters from the top inside of the red vertical pipe. The outer chambers serve cooling. The surroundings of the red […] [Original post on mathstodon.xyz]

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 […]

When we'll find extraterrestrial intelligence we will learn that they like Radiohead #music too.

RE: https://mathstodon.xyz/@quantumjournal/115768000388571692 Our paper with Yudai Suzuki, Bi Hong Tiang, Jeongrak Son, Zoe Holmes and Nelly Ng: We find unitaries which require no auxiliary qubits and yet achieve quantum signal processing transformation. The unitaries are state dependent and […]

- What should more people be passionate about? 3m - Little girls not getting appropriate education. 🎤👇👌

How would you rotate |ψ⟩ to |0⟩? In https://arxiv.org/abs/2510.00302 we show that no measurements are required. I say measurements, because if one would make measurements on |ψ⟩ then tomographic analysis will reveal how to parametrize the appropriate single qubit rotation. However what if no […]

A set of exercise sheets for classical and quantum statistical mechanics that I was tutoring in 2026. Quite advanced and covering many doable theoretical peoblems. The format (and the larger chunk of content) was based on earlier courses tutored by Christian Gogolin and Martin Kliesch which […]

I visited Munich and was thrilled to bump into Spyros Sotiriadis at the cafeteria. He is an expert on quantum field theory and we have researched memory loss effects and structures of light cones together in the context of 1d experiments in Vienna. Even […] [Original post on mathstodon.xyz]

Very neat #chess puzzle 😀 https://lichess.org/training/cLuGg

Don't get put off from this book by the author's glaringly whitened teeth on the cover. It does a good job at - motivating to get into action through the relief of removing clutter and resolving pending commitments by completing them - building a mindset of […] [Original post on mathstodon.xyz]

Oh look, it's me on @standupmaths's YouTube channel again! https://youtu.be/nsj3gTGh9K0 I didn't enjoy this project while I was making it, but it's alright now it's finished, don't you think?

The debate around Musk and the Royal Society is just so frustrating. If those who think it is right to retain him as an FRS were to say "Here, despite his having been a direct accomplice to the dismantling of scientific institutions, destruction of scientific data, spreading of...

Grover's brilliant quantum algorithm has all along been an approximation to imaginary-time evolution. https://lnkd.in/eFMBFUw8 This makes Grover's algorithm no less exciting and makes ITE the more exciting. Our derivation is based on the framework of […] [Original post on mathstodon.xyz]

I wish I had something to say about science today but I don't so here, instead, is an elephant. :)

DB-QITE outperforms QPE - at least in the foreseeable future. We updated our manuscript https://arxiv.org/pdf/2412.04554 and thanks to the contribution of #quantum compilation by Rene Zander and Raphael Seidel(pip install qrisp) we were able to show these results:

Terrific #painting by Min Wae Aung at the National #art#paintingGallery in Kuala Lumpur. The feet in each side seem to be part of a continuous motion so I'm wondering if the concept of this painting could be based on several stills from a video processed to high contrast with a filter?

Cool book about the perspective of #medical doctors onto the art of making a #diagnosis#medical I think the fact that Dr. Cuddy in House M.D. is called Lisa is no coincidence?

We proposed a new way of implementing quantum signal processing even though we didn't plan for it https://scirate.com/arxiv/2504.01077 In most applications, a matrix exponential $e^A$ is defined by an infinite series in A which cannot be truncated without […] [Original post on mathstodon.xyz]
