Tiny spacecraft tested as part of plan for interstellar travel

A list of tech needed to build such a craft[1]. I was interested in how they are thinking about getting a signal back to Earth from Alpha Centauri. It looks like they are hoping a 1W laser might be detectable from such a distance[2].

I hope quantum entanglement (QE) it will be achieved. It's hard to have QE now between billions of chips to achieve an internet without wires/delay, but between 2 chips one on board of the tiny spaceship and the other here on Earth to have instant communication without having 4 years delay is totally feasible right now. I know, I'm a dreamer :)

Very cool. I always thought that the path to interstellar exploration has two options: small devices like this with adequate AI for exploration, and better, larger devices that would have human DNA, micro factories to build bigger factories, and bootstrap life.

Clearly option 1 is much more feasible in the next hundred years or so.
