Będzie ciekawie.
Sąd Okręgowy w Gdańsku właśnie utrzymał w mocy decyzję o zwolnieniu notariusza z tajemnicy zawodowej w sprawie kawalerki pana Jerzego Ż.
Postanowienie jest już prawomocne. Prokuratura może więc wkrótce go przesłuchać.
I nagle pojawia się pytanie: dlaczego tak bardzo nie chciał mówić ?
Bo tajemnica notarialna to nie fanaberia. To obowiązek. Ale w tej sprawie chodzi o konkret: akt z 2012 roku, podpisany w areszcie, w którym Nawroccy oświadczyli, że zapłacili
Jerzemu Ż. całe 120 tys. zł, a on to potwierdził.
Potem wersja się zmieniła. „Płaciłem przez lata opieką, rachunkami, lekami”.
Akt mówi jedno. Wspomnienia drugie.
Notariusz był przy tym. Widział. Słyszał. Zapisał.
Teraz sąd powiedział: możesz mówić.
A on wcześniej mówił: nie chcę.
Ciekawe, co dokładnie usłyszał w tym areszcie.
I czy ktoś naprawdę liczył, że ta tajemnica wytrzyma do końca.

Always great to see hard work pay off!!! Huge congratulations to @GrzegorzŁukasiewicz for receiving the START scholarship from the Foundation for Polish Science (@FNP_org_p) - one of the best recognition at this stage! This is fully deserved! Keep it up! 🙌✨

Breaking astrophysical limits in the search for ultralight dark matter!

Our new paper @Nature demonstrates how a distributed network of quantum spin-based sensors beat the limits set by astrophysics.

Ever wondered if GNOME can search for ELFs? Turns out it’s possible — not only in fantasy books and movies!

Exciting moments at ECAMP in Innsbruck! 🚀 Arash Fard showcased our latest results in Quantum Process Tomography in rubidium vapor during the poster session. #ECAMP2025 was great conference with many facinating talks and interesting discussions. #QuantumPhysics

After discussions about physics, chemisty, neural networks, the structure of Korean industry, it’s time for the final lesson: how to, according to Korean culture, properly hold your glass when someone pours you a drink. @HongkunPark for this incredible year...

My year-long sabbatical at Harvard flew by like a blink. It was amazing. Huge thanks to everyone, especially my hosts @MikhailLukin and @HongkunPark. Paraphrasing Casablanca: "I think this is the beginning of a beautiful friendship/collaboration."

How can you harness #SpinSqueezing or #Entanglement in weak fields where the #LinearZeemanEffect prevails over the #QuadraticZeemanEffect? Our latest work in PRApplied demonstrates a simple yet highly effective way to achieve this goal.

Our latest paper in @NatureComms details a search for axion-like particles using a spin-based interferometer with a 1000 km baseline. While no DM signal was detected, we set new, stringent limits. Read more here: https://t.co/94G5BShexS #Physics #QuantumSensing #Axion

Some projects take a long time — and this was one of them. The good news? We've finally brought it to a happy end!
Check out our latest paper, where we present a new mode of optical magnetometry using light with continuously rotating linear polarization. More details online!

The journey of writing a scientific paper can be tedious, but it's worthwhile when it involves exciting research. That's why I'm thrilled to share our new review article on zero- and ultra-low-field nuclear magnetic resonance. Curious? Dive in: https://t.co/CDnK5XLpKh #NMR

🎉 Another successful PhD defense in our group! On Jan 10th, Marek Kopciuch impressed the referees and earned summa cum laude. Congrats, Marek, and best of luck with new challenges! 🌟 #PhD #Success

There are these moments at the conferences, when the session chair, despite its best efforts, is unable to make the speaker to conclude its talk (PQE 2025, Utah)

[Pustelny group @ JU @ExcitingAtomees]

On Oct 25, 2024, @MikhailPadniuk successfully defended his PhD thesis. During his doctorate he built an innovative sensor that has already advanced theoretical models, setting new boundaries on exotic interactions. Congratulations on this impressive achievement! #PhDSuccess

Not Kraków, but Cambridge. Not lab, but restaurant. Still this is reunion after 3 years

1000 years of clock technology by Andrey Derevianko. This may be the longest time span of clocks that I've ever seen.

Quantum metrology is exciting and vivid field we has been working on for years (even if it was called optical/atomic magnetometry then;-)... Here is a new angle to this theme that we exploited in collaboration with theorists - @KamilKorzekwa and his team.
