Proud to see this finding a home in Physical Review Letters 😌 journals.aps.org/prl/abstract/1…

Congratulations to QuITter Mohammad Mehboudi on being awarded the FWF's prestigious Principal Investigator grant! He will be using this grant to research non-equilibrium quantum sensing here in Vienna! fwf.ac.at/forschungsrada…

Novel bounds on the equilibration of observables in isolated quantum systems help resolve the apparent contradiction between the second law of thermodynamics and unitary evolution. @quitphysics TU Wien @MathsMire Tom Rivlin Jake Xuereb Marcus Huber go.aps.org/3CkRsjk

This is now out in the journal Physical Review X Quantum! Super excited to be able to share this piece of work with everyone. I'm incredibly proud of it journals.aps.org/prxquantum/abs…

New preprint from QuITter Florian! He's involved in this huge new review article on communication using continuous-variable quantum systems. Check it out here: arxiv.org/abs/2501.12801

New preprint: QuITters Shuheng and Giuseppe continue their work studying high-dimensional entanglement and quantum metrology. Here they derive a criterion for witnessing entanglement dimensionality using the Quantum Fisher Information arxiv.org/abs/2501.14595

This paper from our group has now been given a lovely write-up on the Atominstitut's website by Florian Aigner from TU Wien (with contributions from the authors of the paper) Check it out in English: tuwien.at/en/phy/ati/new… ...or in German: tuwien.at/phy/ati/news/a…

New preprint! Florian, Marcus, and Pauli join a big group studying tiny clocks. How do the thermodynamic costs of creating clock ticks compare to the cost of recording them? How does this relate to the quantum-to-classical transition? Find out here: arxiv.org/abs/2502.00096

New Phys. Rev. Lett. from QuITters Nayeli, Nico, Marcus, and Pharnam! It's freezing cold here in Vienna, so we're definitely in the mood for a cool new paper on efficient cooling methods for quantum systems 😎🥶 journals.aps.org/prl/abstract/1…

Congrats to theory hotshots Phila, Nico, & Eliza, who join a crack team of Atominstitut experimentalists in this new preprint. They propose a new method for certifying entanglement in electron-photon pairs, with applications to electron microscopy arxiv.org/abs/2502.19536

Congrats to Gláucia, Eliza, and their teams and collaborators for securing a big FFG grant to work on some very cool science! Stay tuned for some exciting developments in quantum cryptography from our department tuwien.at/en/tu-wien/new…

New preprint! QuITter Jakob brings us this cool new work on randomness generation in the classical and quantum realms. Featuring a very fun title page image: arxiv.org/abs/2503.05528

This preprint is now out in npj Quantum Information! nature.com/articles/s4153…

🪄Do 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! 🧙✨🤩 arxiv.org/abs/2503.18734

This paper has now been published in the journal Quantum! quantum-journal.org/papers/q-2025-…

"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 bsky.app/profile/did:pl…

Here's a preprint roundup from the last 10 days while admin was away 😎 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 arxiv.org/abs/2504.07814

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 arxiv.org/abs/2504.08298

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 arxiv.org/abs/2504.13163

Finally, Philipp and his collaborators study the theory of high harmonic generation using quantum optics, and in particular the notion of optical coherence arxiv.org/abs/2504.13287
