It's immensely satisfying when something that you have been thinking about for eight years gets finished - thanks to two outstanding @TCD_physics @QuSysTCD students Laetitia and Artur - the story of Information Geometry of NESS to NESS transitions is out:

This paper shows how resource theory provides a unified language to describe all Mpemba effects, demonstrating that both the thermal Mpemba effect and its symmetry-restoring analogues arise from the overlap of initial states with the slowest relaxing mode: https://t.co/22Pe6n4RNC

In todays preprint we uncover universal thermodynamic scaling in dissipative quantum phase transitions
https://t.co/jwdYv7lsKO . Using information geometry we show that the nonadiabatic entropy production scales universally with quench time

Very happy to be involved in this great work - a PRB editor’s suggestion by @tcddublin student Peter O Donavan

Physicists disagree wildly on what quantum mechanics says about reality, Nature survey shows https://t.co/a2yH0vscYC

[Goold_Group @QuSysTCD]

Our latest work is finally out - unifying many seemingly disparate instances of the notorious Mpemba effect in classical and quantum dynamics such as symmetry restoration and thermalisation using a resource theoretical approach: read here: https://t.co/EbNqMeckLa

[Goold_Group @QuSysTCD]

Great to see the latest @QuSysTCD @tcddublin paper on Physical Review Letters today - where we show that quantum batteries with higher charge can discharge faster than less charged ones and other anomalous effects https://t.co/4A9ruNyqiP

Minister @lawlessj has secured Government approval to sign the European Quantum Pact, a joint declaration by EU science ministers recognising the transformative potential of quantum technologies.

[Goold_Group @QuSysTCD]

The latest work from @QuSysTCD @tcddublin. Great work by postdoc Sam Jacob who derived Kubo formulae without time dep classical driving but rather autonomously by another quantum particle. A generalised FDT appears outside of linear response read here https://t.co/injng6s6dj

And it’s done - now time for a beer

@jfitzsimons @horizon_quantum @NiccoloDeMasi Congratulations Joe !

[Joe Fitzsimons @jfitzsimons]

Delighted to announce that we've signed a non-binding letter of intent with dMY Squared Technology Group to take @horizon_quantum public. We couldn't ask for better partners on the journey to the public markets than Harry You and @NiccoloDeMasi.

All You Ever Wanted to Know About Quantum Error Correction

In a brief yet thorough summary that appeared last week on the pre-print server, a group of quantum computing experts discussed the challenges on the way to commercially relevant quantum computers. Among other things, they confirm that speedups from quantum computers can reliably be expected for certain problems but that quantum error correction still has a long way to go to scale with platform size.

Nice to have this one published - well done again to @QuSysTCD PhD student Laetitia Bettmann: Information geometry approach to quantum stochastic thermodynamics https://t.co/JuaBr1Pf9w

[François Damanet @DamanetFrancois]

I really like this perspective paper that provides some (as neutral as possible) consensus on timely questions in the field of quantum computing, as well as debunking myths. We need more of this. Thanks for the initiative!

[John Preskill @preskill]

Useful perspective, clearly written and well-reasoned.

[Zoe Holmes @qZoeHolmes]

We had fun arguing about the prospects of near-term quantum computing in Lapland/Oxford

In https://t.co/O5pDQfIFok we frame our (reasonably converged) conclusions around common 'myths' concerning error mitigation, VQAs and resource estimates.

Feedback/discussion welcomed!

[Zoltán Zimborás @ZoltanZimboras]

To reach some consensus about the prospects of near-term (nisq and early ft) quantum computing, we had a 3-day discussion event (“Quantum Now”) in Lapland with both optimists and pessimists. This continued at SeeQA 2024 in Oxford. See our conclusions here https://t.co/UaQB9LmTqF
