Congratulations, Dr. Xuereb! 🔥🧊🖥️👹

I think becoming a Dulwich Quantum Meme is a good way to cap off the PhD

My mom: What have you been doing all these years? Me:

My deepest congratulations to my brother in arms, the freshly minted Dr. @mathsmire.bsky.social 🥳🥳🥳🥳🥳

One of the best introduction of thermodynamics I've ever read. Thermodynamics as the old man at house party of theories of physics being introduced by his granddaughter, entanglement theory. Douglas Adams like brilliance from Matteo Lostaglio and a good reminder that a phd thesis can be playful.

Beautiful @johncarlosbaez.bsky.social thread, feels like old quantum twitter again 😭

Here's how Hideki Yukawa predicted the mass of the particles that carry the nuclear force. It was a stunning episode in the history of physics, and the start of a new era. (1/9)

The Qalypso School on Quantum Science in Malta returns for its 3rd edition Aug 31 - Sep 4 this year! 🏖️ We have a great line up of lecturers covering Quantum Optimisation, Quantum Thermodynamics and Quantum Gibbs Sampling. Pre-registrations opens today at forms.gle/3NkMJ3Br9V8b... Do Share!

Landauer was such a gangster. Maybe I should get this on a t-shirt (ieeexplore.ieee.org/document/521...)

From one tick to the next, small timing uncertainties in clocks usually add up because of the independence of errors. Using fermions tunneling through a quantum wire as clock ticks, we found a way to build a clock where errors cancel out rather than accumulate. arxiv.org/abs/2601.10785

Can Gottesman–Kitaev–Preskill (GKP) encoding turn homodyne detection into a practical tool for revealing Bell nonlocality? The answer is yes, and in fact GKP states also lead to strong and robust multipartite nonlocality with homodyne detection! Today on arXiv: arxiv.org/abs/2601.16189 1/n.

(1/2) Got on a train a week ago headed from Vienna to Lausanne and spent some days hanging out at EPFL. Was fortunate to be able to share our insights from our recent PRX Q on Cooling a Qubit using N Others at -- recording here 👁 Warm thanks to @qzoeholmes.bsky.social and Jon Conrad for having me

🧵 Here is a thread reviewing what in my view were some of the stand out works in Quantum Thermodynamics that appeared on the arXiv for 2025. (1/14) #quantum #thermodynamics

Quite happy seeing this work out now in @prxquantum.bsky.social It was great fun working with my collaborators on this one. Especially pleased to have brought some graph theoretic combinatorics to Quantum Thermodynamics 🔥🧊 journals.aps.org/prxquantum/a...

Cooling a Qubit Using n Others

By extending the algorithmic cooling problem to qubit machines with arbitrary energy structure, this work reveals fundamental limits on quantum cooling and shows how a reservoir's internal energy land...

(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. scirate.com/arxiv/2506.1...

Here are a couple of neat theorems due to John Conway and Cameron Gordon (1983): Any embedding of K_6 in 3D has two linked triangles (red and blue below). Any embedding of K_7 in 3D has a knotted Hamiltonian circuit (red below). Article: people.reed.edu/~ormsbyk/138...

If you wanna know more about where I'm from, where it's at and why it's there -- this article is a good analysis of the economics and corruption that led to the current state of affairs in Malta.

POLITICO Europe@politico.eu · 9mo ago

After ex-premier Joseph Muscat took power in 2013, Malta witnessed an astonishing economic boom, fueled by a no-holds-barred drive to court the world’s wealthy. But the giddy growth spurt led to serious deformities — and a sprawling corruption trial.

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

arxiv.org/abs/2511.02683 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.

arxiv.org/abs/2511.00852 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.

No, classical gravity does not entangle quantized matter fields

"no amount of QFT machinery will ever change that fact" Who needs reality TV when you've got quant-ph arguments about the quantum nature of gravity I'm biased towards the guys with the peer reviewed careful math, not the overnight 2 eq arxiv posting tbh arxiv.org/abs/2510.19969

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!

Quantum arXiv today.

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!

A Thermometer for Measuring Quantumness | Quanta Magazine

“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 made a zine about quantum gates and distributed it at @unitary.foundation's unitaryCON this two weeks ago. check it out :) and lemme know what you think nates.place/static/ng01....

Good morning from TQC 2025 in Bengalore IISC 🇮🇳 I'm here spreading some Quantum Thermo propaganda to the Algo, Crypto people - pass by poster 72 if interested in (arxiv.org/abs/2505.15887) Bengalore has been overwhelming, awesome, beautiful and tasty so far

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?

Anyone else headed to TQC in Bengaluru and hanging out a bit the week after? Do send a message if yes and you're up for hanging out after the conference. 😄 tqc-conference.org

(1/n) I’ve been binging some golden oldies from the optomech boom of the late 2000s and was surprised to find that the currently popular gravitationally mediated entanglement "is gravity quantum" experimental proposals -- find their origin there. Here’s a little thread on that lineage. 🧵

I've gotten into dumpster diving through Scirate for old discussions. A journal club with a time machine. 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 scirate.com/arxiv/1909.0...

Warm and well deserved congratulations to @itsmealeale.bsky.social and coauthors on the most beautiful review to ever grace the pages of Physical Review 🎆 I'm sure many students will be thankful for years to come for having learnt about how to carry out thermodynamic exorcisms from this tutorial 😈

Alex@itsmealeale.bsky.social · 12mo ago

Our tutorial "A friendly guide to exorcising Maxwell's demon" (journals.aps.org/prxquantum/p...) is out! The big question after the tutorial is whether I’m finally done drawing demons?
