Poetry for Physical Review Letters #PoetRL

There was a system in a physical state, that could not escape its thermal fate. The description was hard, and with obstacles marred, but tensor networks still did great. About this #PoetRL Paper Title:   Tensor Network Annealing Algorithm for Two-Dimensional Thermal States Authors:   A. Kshetrimayum, M. Rizzi, J. Eisert, and R. Orús Reference:   Phys. Rev.

We are a bunch of teeny quantum flecks. We all are in a state - no, not a rage, I mean, we've got weird features, and you gauge each of these on a scale of 1 to X. One such feature is bliss: It gives us clearance to be both heads and tails, both up and down, to walk concurrently all streets in town, and fuel computers. We call this coherence . But some of us are not that well endowed, so here we ask: How well can you pick out the most coherent critters from the crowd? You will need a distillery! No doubt, it should be fit for purpose, even though sometimes it fails, and you need one more go. About this #PoetRL This is a double feature for two papers. Paper 1 Title:   One-Shot Coherence Distillation Authors:   Bartosz Regula, Kun Fang, Xin Wang, and Gerardo Adesso Reference:   Phys. Rev. Lett. 121, 010401 – Published 3 July 2018 URL:    https://doi.org/10.1103/PhysRevLett.121.010401 Paper 2 Title:   Probabilistic Distillation of Quantum Coherence Au

Our world is big and messy, but we agree that certain facts are objectively true: Earth is not flat, despite a minority of people still dispute this hitherto. What else, we all concur a billiard ball hit by a cue with ordinary force, will never just go through a masonry wall without leaving a hole in a brick course. But in the microscopic quantum realm particles can be in two places at once, so how does objectivity unwhelm? It's natural selection: At a glance, the more observers look at the same cat, the more consensus will be formed hereat. This Darwinian revue was known to occur for atoms and all that. We prove it holds for infinite "cats" too. About this #PoetRL Paper Title:   Generic Emergence of Objectivity of Observables in Infinite Dimensions Authors:   Paul A. Knott, Tommaso Tufarelli, Marco Piani, and Gerardo Adesso Reference:   Phys. Rev. Lett. 121, 160401 – Published 17 October 2018 URL:    https://doi.org/10.1103/PhysRevLett.12

Two friends, Alice and Bob, loved to converse, they liked to exchange their secrets and their views, but when they tried to swap a quantum verse, price was too high: they couldn't pay their dues. So they had to resort to a clever trick: investing in good hardware and their wits, each of the two got a quantum sidekick to assist in the transmission of the bits. From then onwards, messaging was a breeze, and - how surprising - actually so cheap, that they got credit back with each new bill, The more they talked, the more they gained, at will, resources (like entanglement) to keep. ... This must be what convinced the Referees!

Hi there! I am a mathematical physicist based at the  University of Nottingham  (UK). My main  research focus  is quantum information theory and its applications. As a late new year resolution for 2019, I am launching the #PoetRL challenge! I pledge to write a small poem for each paper I publish in  Physical Review Letters . (Disclaimer: I am not affiliated with PRL or with the  American Physical Society !) Hopefully this will make the papers more accessible to a broader community, and overall it could give rise to an interesting crossover experiment between physical sciences and literary arts. Calling all my colleagues here: If you find this idea cool and you wish to contribute, please write your own #PoetRL and send it over via the contact page . It could then be published on this website.
