A recent @nature.com article claims that classical (unquantised) gravity produces entanglement. We show that their model does not produce entanglement. Even if the model produced entanglement, it would be mediated by the quantised matter interaction, and not gravity. scirate.com/arxiv/2511.0... 🧪⚛️
Classical gravity cannot mediate entanglement

Gravity mediated entanglement arXiv posting of the day.
This time from across the road, IQOQI Vienna's Andrea di Biagio reminds us about important assumptions different models make and why it's hard to make a model independent no-go theorem.

The saga continues, my favourite of the reactions to the Aziz, Howl paper so far.
A sharp and straightforward passage from Diosi makes clearer why the semi-classical treatment does not agree with the calculation of Aziz and Howl.

V3 of this manuscript is on the arXiv today : arxiv.org/abs/2505.15887
You'll find :
-a friendlier presentation for people from outside the quantum thermosphere
-a probabilistic bipartite heat exchange that approaches the capabilities of the n-partite interaction of V1
-cleaner inequalities!

Amazing to see the work of @itsmealeale.bsky.social and Partyk L Bartosik highlighted like this.
Having followed it as it was written and knowing the hard work that was poured into it, really brings a smile to one's face to see it highlighted.
Yes to detecting entanglement using thermodynamics!

“Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect quantum entanglement without destroying it.

Considering creating an anonymous google form survey for researcher in QInfo with questions on what roles collaborators have in projects.
E.g. What roles does a last author have in a project vs What roles does a first author have
Would you fill it out? What questions would be interested in?

I think the number of single author arXiv postings on quant-ph is steadily increasing. E.g. today 7/48 postings were single author.
Has anyone else been noticing this?
Surely it's due to GPTs being good paper writing assitants, right?

Here's one on how you could build a Qcomputer out of 1 photon but "a photon as wide as the universe would be like ∼100 qubits" from @mankei-tsang.bsky.social

Easy to feel powerless in times like these.
Trying to remember that science is a political act and a force that brings people together from all over the world out of excitement for the beauty of nature.
In this sense, science is an act of defiance against those that wish to divide humanity.

(1/n) Today on the arXiv, we examine the folklore that cooling a quantum system with access to another requires one to order their joint state eigenvalues in decreasing order and find that this sorting is actually dictated by a simple set of inequalities.

I think a lot about how Aaron Swartz committed suicide while facing a probably long jail sentence for download some of JSTOR, but no one at Meta is going to face any repercussions for using all of Libgen to train its AI.
Someone else said something very similar to this the other day, but.
It really burns me that our (millennials') generation was legally terrorized for like, downloading Radiohead discographies
But we're supposed to be ok with billionaires stealing human intellectual output in its entirety bc AI

What started as informal discussions on the Danube beach in Vienna during QTD2023 has been published at last. Trying to come up with an experimentally feasible quantum clock we came across a rich model – the ring clock – that overturned a common wisdom in the community. doi.org/10.1038/s415...
