can anyone ELI5 what's the impact of this research?

Quantum computers are difficult to scale because of noise. Applying a quantum gate to a qubit using teleportation is a protocol for performing fault-tolerant quantum computation.

I don't know what 5 year olds you hang out with, but I think this would have gone over their heads ;)

On Hacker News everybody's five year old kids:

1. Configure and run their own Minecraft Server

2. Are fully proficient with the linux commandline

3. Are skilled in basic safe cracking techniques such as auto-dialling, weak point drilling, scoping and the use of brute force methodologies including the use of thermal lances (having acquired relevant Health and Safety accreditations).

And besides that they are on their third startup, have a blog, will debate the finer points of faking it until you make it with gusto, and are proficient in LISP, Rust and Elixir.

And will explain monads to their parents

Which is why we got them in the first place! Failure to contain I mean.

So did any of these five year olds notice this sentence?

> Using a theoretical protocol developed in the 1990s, Yale researchers experimentally demonstrated a quantum operation, or “gate,” without relying on any direct interaction.

They're basically saying it's magic. But no 5 year olds I hang out with are any good at magic yet.

Quantum teleportation is the transmission of a quantum state using an entangled pair and two classical bits. No magic needed.

It's a huge step for building the next generation of computers. Imagine you want to listen to your favorite music in a very busy street with lots of cars and people without headphones. Not very enjoyable. These guys figured out a way to suppress all noise with a special headphone. They move the information from your phone directly to your ears. That's obvious for you I suppose, but it was really hard to do that on vert very small scales these computers operate on.
