“In the future, our system could be part of a global quantum network transmitting quantum signals to receivers on Earth or on other spacecraft,” says Aitor Villar, lead author of the study. “These signals could be used to implement any type of quantum communications application, from quantum key distribution for extremely secure data transmission to quantum teleportation, where information is transferred by replicating the state of a quantum system from a distance.”
OK, OK, so it’s not the first time quantum entanglement has been demonstrated. But it sure is the smallest. Only 20 cm by 10 cm!
Now we only need a few thousand of these things and a way of somehow making tangled photons actually carry encrypted messages…
(Sorry, thinking of the SF novel I should have published by now…still figuring out the last two chapters!)
See more at New Atlas (note: I seriously doubt the CubeSat actually looks like that picture when it’s doing its thing).
One day, maybe sooner than we think, a consideration of the ethics of the treatment of rational, sentient machines might turn out to be more than an abstract academic exercise.
From last June, but still a worthy topic for debate, particularly as the use of robots increases for retirement homes, nursery school programs, hotel reception lobbies… (also the topic of a short story I wrote in 2000 but still haven’t published outside of a grad student journal…)
NASA tellsInversethat the payloads will need to measure no more than 100 millimeters by 100 millimeters by 50 millimeters, around the size of a bar of soap. They will also need to weigh no more than 0.4 kilograms (0.88 pounds) and be able to withstand external temperatures between minus 120 degrees Celsius (minus 184 degrees Fahrenheit) and 100 degrees (212 degrees Fahrenheit). These are the maximum limits, but smaller and lighter is preferred.
Yow, that’s wicked tiny. But small price to pay to set up a Lunar Space Base from which humanity can expand into the expanse.
