New preprint! arxiv.org/abs/2602.10882 We measure anti-bunching and witness quantum non-Gaussian states from high-harmonic generation. High-harmonics are generated in a strong field process with unique properties, distinguishing it from the established quantum light sources.

10 years ago today, we told the world "We have detected gravitational waves. We did it!" Relive the moment we shared our result with the world www.youtube.com/live/aEPIwEJ... #GW10Years #OTD 🔭🧪⚛️ 🎂

Vor ziemlich genau 8 Jahren hat Jörg Meuthen, ehem. Vorsitzender der AfD, gesagt, er sehe in den Innenstädten "noch vereinzelt Deutsche". Die Vorsitzende der CDU, Angela Merkel, hat ihm umgehend widersprochen. Friedrich Merz hat heute die Sprache und Position der AfD übernommen.

“The shining star of our family has dimmed his light for us in this life … We are heartbroken to announce that Michael D’Angelo Archer, known to his fans around the world as D’Angelo, has been called home." More on D'Angelo's life and legacy: www.rollingstone.com/music/music-...

High-order harmonics are non-classcial! This has recently been further substantiated by @kittenstate.bsky.social and his colleagues of the QUANTUM group at LOA. loa.ensta-paris.fr/2025/09/09/q... Their observation of a displaced squeezed state is now published in @physrevresearch.bsky.social.

Did you know your MacBook has a sensor that knows the exact angle of the screen hinge? It’s not exposed as a public API, but I figured out a way to read it and make it sound like an old wooden door.

Are you a student or early-career researcher in quantum computing or quantum information? Then the following is for you. We're organising a focused, community-driven conference at Leibniz Universität Hannover, hosted by Prof. Robert Raussendorf. 🗓️ Save the date: August 27–29, 2025

Spending a lovely afternoon of writing and watching tour de france

Nature study: when do girls fall behind in #maths? During their 1st year at primary school. 4 yr study, 2.6M French children. By comparing kids born a month apart but in diff school years they show it's education, not age, that triggers the gap☹️ 🧪👩‍🔬 ℹ️: www.nature.com/articles/s41... 👇Excellent 🧵

Fuck. RIP to Sly Stone. One of the greatest ever.

Wow - I don't remember seeing Magnus choking like this. Props to Gukesh for playing on and sensing the opportunity to take down his predecessor for the first time in classical control. #NorwayChess

After correcting tens of unintended features in my code, I finally arrived at finding yet another one

1.8% was enough for Dallas. Lucky for them, they will draft the tall guy and possibly win their fan support back

Now replacing the lofi girl with the Vatican chimney cam. Same vibes, just with a bit more suspense.

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back. This was the largest political gathering in Denver since Obama in 2008. Also bigger than the 2024 DNC. And the largest ever rally in Bernie’s career (and obviously, mine too).

They probably will only start to worry when the size of funds will be cut under new government

Vinnie winnin'

As a sphere, I couldn't handle the social pressure exhibited by unit spheres. Unrealistic stereotypes also exist in the world of spheres.

Klasse, Habeck ein Buch geschrieben, in dem er das BWV durcharbeitet schön mit Harmonieanalyse und allem drum und dran, dem Titel nach zu urteilen. Werde ich mir auf jeden Fall geben!

No chatbot will ever trigger the same feelings in me as clippy did

A team led by physicist Chien-Shiung Wu obtained the first experimental confirmation of “parity violation,” in the decay of Cobalt-60, #OTD in 1956. Her theory colleagues received a Nobel for the prediction, but she was left off the prize. 🧪 ⚛️ 👩‍🔬 Image: Smithsonian Institution Archives

In 1994 when I worked at Kitt Peak National Observatory, @todlauer.bsky.social made an off-hand comment about grape plasma in the microwave. Being an experimental physicist (read as “nerd”) I immediately tried it during night lunch. Who knew it was come to this? 🧪🔭⚛️

Chess is now taken over completely by the youth. Amazing

Science bluesky is so serious - feels more like LinkedIn sometimes. I am also not helping though

Data data data

LOA's QUANTUM group, with @kittenstate.bsky.social as lead author, have ou published a Phy.Rev.X Quantum-paper, proving high-harmonic-generatio to produce non-classical light states. loa.ensta-paris.fr/2024/11/12/e... doi.org/10.1103/PRXQ...

Können die bei phoenix mal zu linder rüberschalten? So Champions League Konferenz mäßig

New pre-print out! Following up on our most recent work, we analyse the nonclassical state from high-harmonic generation. Estimation of the squeezer distribution and Schmidt number further confirm HHG as a promising quantum source of light. arxiv.org/abs/2411.02311

when a baby is screaming in public i think about them as a little metal singer and honestly it does help

Pretty figures win over referees

Implementing corrections to a draft. A } is missing somewhere now. It doesn't compile anymore. I had better starts to a Friday.

Got my first article accepted! It will be soon available on PRX Q. Studying the photon statistics of high-harmonic generation, we found surprising results. Apparently, HHG light can be squeezed and has non-classical properties ! journals.aps.org/prxquantum/a...

Time Tagging technology is still far from reaching Planck time resolution, and it will probably remain like that

What's the impact factor of 'GEOlino' ?

First glance at new data: Wow, that looks actually pretty nice ! Second glance at new data: omg, what is happening I don't get it

Do a PhD, they said. You will get to use the latest high-tech. Found while cleaning the lab.

First time having an article in peer review feels like: Why so critical? Can't you just trust me, please?

Grand Swiss was pretty exciting to follow - so nice seeing the 'youngsters' quickly establishing themselves at the top. Incredible tournament by vidit.

"Being a physics researcher is very demanding but very rewarding as well. I am strongly against the idea that you need to devote your whole life to your career. You can have a family and a life outside physics and still be successful in your field." I feel this is sometimes not stressed enough.

Awesome choice of laureates! This field is getting some well deserved recognitio. Glad to be working on it - still many open questions left to answer

This is impressive on atleast 5 + 1 levels.
