If objects in motion are like rainwater flowing through a gutter and landing in a puddle, then quantum objects in motion are like rainwater that might end up in a bunch of puddles, all at once. Figuring out where quantum objects actually go has frustrated scientists for years.

Now a Yale-led group of researchers has derived a formula for understanding where quantum objects land when they are transmitted. It’s a development that offers insight for controlling open quantum systems in a variety of situations.

“The formula we derive turns out to be very useful in operating a quantum computer,” said Victor Albert, first author of a study published in the journal Physical Review X. “Our result says that, in principle, we can engineer ‘rain gutters’ and ‘gates’ in a system to manipulate quantum objects, either after they land or during their actual flow.”

This is a nice vid but there are two things to note.

1. he does not mention Callisto in place of Europa. Europa gets enough radiation to kill you in a day where on Callisto you would not even get the radiation you get here on Earth.

2. It might be possible to puff up a given asteroid by creating a cylinder within as he points out, but filling it with water and then heating it from outside and once it’s molten the water will expand and blow the asteroid to a larger size. It may be possible to turn a 1 mile wide asteroid into a ten mile wide habitat. I do not know how well it scales up to larger asteroids.


Professor Stephen Hawking has warned that mankind will not survive another millenia unless it makes a home beyond Earth’s atmosphere.

The celebrated physicist was addressing a lecture audience at the Oxford Union debating society on Monday evening when he gave the stark warning.

“Most recent advances in cosmology have been achieved from space where there are uninterrupted views of our Universe,” he said “but we must also continue to go into space for the future of humanity.
