Poetry for Physical Review Letters #PoetRL

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.

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.

There was a wee patient with flu Whose temperature couldn't be seen through.     What would be super     As thermometer? A two-level atom will do.

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.

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.

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.

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!
