Hey quantum twitter, we're on Bluesky! Follow us there for updates from us all here at the Atominstitut's theory division, including new papers, event announcements, and more. https://t.co/CXpjRfD77G
Congrats to QuITter Phila Rembold on being awarded an FWF ESPRIT award! Among other things, she'll be using her expertise in quantum optimal control to develop new techniques for entanglement estimation, sensing and metrology ๐ฅณ๐ฅณ
https://t.co/TIFXhixD6j
This has now been published in Phys. Rev. Lett.! Congrats! https://t.co/fRwwEiy1EE
New from QuITters Florian and Marcus: in this preprint they propose a new framework for computing key rates in quantum key distribution, for the tricky case of high-dimensional entanglement
https://t.co/biMG52c4Og
New preprint from Alberto: how long do quantum systems take to thermalise? Here the authors show that quantum theory imposes a fundamental lower bound on this time!

Father of twins, theoretical physicist, quantum thermodynamicist;
Thermodynamics and control of information in complex quantum systems.
New preprint, featuring Jake, Alberto, Marcus, and Pharnam, along with two people who worked with us here at the Atominstitut. They find that the sorting involved when cooling a quantum system using another one is dictated by a simple set of inequalities

New preprint: Moha and colleagues get into the swing of things with a study of the thermodynamics of... pendulum clocks?
...oh, right! QUANTUM pendulum clocks!
https://t.co/aOTIH7Xfts
Florian, Yuri, Pauli, and Marcus have a new paper out in Nature Physics! The snappy title says it all: Precision is not limited by the second law of thermodynamics! https://t.co/q2CyGFLYMn
This paper is now out in PRL! https://t.co/15P605lJ3J
In this new preprint, QuITters Shuheng, Marcus, and Giuseppe contributed to experiments that used randomised measurements to robustly certify high-dimensional entanglement
https://t.co/TxZ14rUPh9
This paper is now out in Nature Communications! https://t.co/jAtVG7Ce9R
New preprint: Marcus joins a team which managed to produce strongly entangled, high-dimensional quantum states of photons in a lab, expanding the range of entangled states that it's possible to study and use
https://t.co/k1GR0vCikX
And here you can read Yuri explain the result in his own words to Der Standard (auf Deutsch!)
https://t.co/23dT6m2BWd
Congrats to Yuri for having his new PRL be an Editors' Suggestion! A model of boson transport with dissipation turns out to have surprising connections to a fermionic scenario, via its link to a universality class for surface growth models
https://t.co/foT9yK0MrR
To us, every year is the International Year of Quantum Science and Technology, but it's nice that it's official now...
And this week, Marcus spoke to esteemed science journo Emily Conover about the future of quantum theory, with some hot takes ๐

https://t.co/k1GR0vCikX
Time crystals! There's been a lot of hype around them recently. In this new preprint, Marcus and others explore an overlooked aspect of them: how good are they as (quantum) clocks? The answer: potentially very good!
https://t.co/rtjOsJ2xWs
Finally, Philipp and his collaborators study the theory of high harmonic generation using quantum optics, and in particular the notion of optical coherence
https://t.co/jOaRkmKkUe
Third, Phila has a preprint working with experimentalists to verify entanglement between position and momentum degrees of freedom in electron-photon pairs using a transmission electron microscope
https://t.co/tCTjORmHX7
Next, Florian has a preprint on quantum key distribution, where he and colleagues succeed in transmitting quantum keys 10 km aways at over 1.2 Gbits per second
https://t.co/gBSROL1xVT
Here's a preprint roundup from the last 10 days while admin was away ๐
First, the first preprint of PhD student Julia (along with Giuseppe) is out: They looked at entanglement monotones for many-body systems, including near phase transitions https://t.co/7GpqllJuSG
"X" is asking us to celebrate our third anniversary on the platform! A perfect excuse to remind everyone to get off of here! Follow us elsewhere! Stop reading this! Go! #MyXAnniversary
https://t.co/e8otaZgzn5
This paper has now been published in the journal Quantum! https://t.co/uavwFkWN6m
Here's a new post-Xmas arXiv posting from QuITters Klรกra Baksovรก, Elizabeth Agudelo and Nicolai Friis, looking at continuous variable GME activation! https://t.co/ISeZWqG9FV
๐ชDo you believe in magic? In this enchanting preprint, new PhD student Patrick conjures up a proof that Bell Inequalities can witness an arcane quantum computing resource called non-stabilizerness, also known as magic! ๐งโจ๐คฉ
