It's a catastrophe!

Anderson perturbed his Fermi Sea, To his surprise, he found orthogonality,       He proclaimed: "A catastrophe indeed",       But now we must concede, That it's just due to energy-time uncertainty!

TUR de force

Extension Island

Alice and Bob: 't was love at a first glance. He thought she really was his one soulmate, But to be sure, one day, he set to rate How faithful she was in their romance. Alice was then invited to a weird place, A kind of mirror maze, in which she found Lots of lads, looking just like Bob all-round, And each of them eager for her embrace. A monogamy test was thus declared: The more clones Alice got entangled with, The less for her authentic Bob she cared. You may think this is nothing but a myth, But quantum social rules are so finespun: True love cannot be shared with more than one.

A (no-)distillation poem

This is a distillation poem In two parts: purely, the first one States the ground of the problem, The other shows it can be outdone. Part two is bound to half the lines But strictly words from the first piece. A no-go theorem undermines The rates of coherence to increase. Coherence is strictly bound But, from purely states, Distillation can ground The increase of rates.

Reaching for the stars

Night time. You cast a glance up in the air. You glimpse a spark of light: You want to know If it’s from just one star, or from a pair. How can you answer this? Well, read below. Light travels from the source up to your eye But gets a bit blurred out along its path. So, even though they’re spaced out in the sky, Two stars might look as one. Let’s do the math. If, on your image plane, you get two spots With smaller distance than the light’s wavelength, Lord Rayleigh says you can’t resolve the source. But quantum sensors let you beat this curse Even for very close points: That’s the strength! The applications of this study are lots. You can connect the dots… From bioscience to astral observation Up to 3D super-localization.

Every little quantum helps

Today we’re gonna play a guessing quiz. First, pick a little marble from your drawer. Then push it into a mystery box, whose core is like a maze of many paths. Now, whizz, Look at the ball when it comes out and guess: Which way, inside the box, did it go through? Was it path number one, or three, or two? Let’s try and assess your chances of success. If your marble’s a cheap, generic brand, the various paths won’t have that much effect. But, if you choose a rather high-spec ball, With every different turn, during its roll, a distinct shine the sphere’s going to reflect. Just spot the change and win! Do you understand? Let me briefly expand and give you the tagline (pardon the garble): Every quantum resource is a good marble.

The Office Aide

This is a story which may sound familiar: A man, called Bob, had lots of work to do. However, his condition was peculiar, His brains were tied, and his energy too. One day, a keen co-worker joined the office, Resourceful, with energy to spare, But with no tasks to do. Her name was Alice. She noticed Bob was swamped in despair. Then she proposed a deal: She’d do the thinking And give him clear instructions. Bob, in turn, Could sort stuff at his desk with zero sweating. They would share any revenue in return. And it worked out! They did a stellar job. It was such a dream team: Alice & Bob.

Single malt super spirit

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.

Survival of the infinitely fittest

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.

Paid as you go

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. ...

Welcome

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.
