New results on asymptotic state interconversion open the way for novel coherent thermodynamic protocols. @marcotomamichel @QuantumChubb @joerenes

@FRevson @siddhantphy Yeah our decoder (https://t.co/K88DMCeng9) would be impractical for larger codes.
But we shouldn't be too quick to conclude that an impractical TN is needed.
Our hope is that new tricks can be developed; there's no shortage of TN research! (I'm still hopeful that BP can work.)

@stotti_alex @quantum_graeme Congrats on the result! Also, the short paper was very readable, not an easy task.

[Joe Renes @joerenes]

@FRevson @siddhantphy Ideally, yes. But we're essentially working at fixed bond dimension, so the approximate contraction method deviates more and more from ideal contraction as the size of the tensor network increases.

[Joe Renes @joerenes]

@earltcampbell @siddhantphy It's TEBD-style layer by layer contraction from one face, where the face at each stage is described by a PEPS or similar. Truncation is done using the "simple update" rule. Unfortunately we didn't get much improvement from recent methods, eg BP https://t.co/w4IPX1mPUY

@siddhantphy Thanks! The full paper (Christophe, @QuantumChubb, and myself) is here: https://t.co/mACyGHGvs0

New paper on quantum dichotomies and quantum thermodynamics is finally out! https://t.co/naszSltTte

Together with Patryk Lipka-Bartosik, @joerenes, @marcotomamichel, and Kamil Korzekwa we look at asymptotic conversion rates of quantum dichotomies beyond the first-order. (1/6)

Happy to announce some light reading: https://t.co/mdSQ2iyrZ7

@felix_led @enclanglement @markwilde @quantum_graeme @kenbrownquantum @RichardKueng I don't think that's in the contract. I'll have to ask about a pdf on my website. If I ever do this again, I'll be sure to keep that possibility -- can correct all the mistakes right away! Also, wide availability is nice. (At the moment, ETH library does not even have access. 😅)

@octonion @markwilde @quantum_graeme @felix_led @kenbrownquantum @RichardKueng Thanks!

[Joe Renes @joerenes]

@enclanglement @markwilde @quantum_graeme @felix_led @kenbrownquantum @RichardKueng well ...
