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.

Stochastic liberation

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.

Spectacular connection

I could not see your side However hard I tried I had to know it In order to commit He said “There is a limit in our separation” But something is found beyond our imagination The empathy is finally around And together we are bound About this #PoetRL Paper Title:   Towards Superresolution Surface Metrology: Quantum Estimation of Angular and Axial Separations Authors:   Carmine Napoli, Samanta Piano, Richard Leach, Gerardo Adesso, and Tommaso Tufarelli Reference:   Phys.

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.
