Is teleporting a death sentence?

“Beam us down, Mr. O’Brien! No, wait, I didn’t meaaaannnnnnnnn……”

Some would argue that having one’s “molecules scrambled,” as Dr. McCoy would put it, is actually the surest way to die. Sure, after you’ve been taken apart by the transporter, you’re put back together somewhere else, good as new. But is it still you on the other side, or is it a copy? If the latter, does that mean the transporter is a suicide box?

An old article (2017, whose impetus was the imminent release of ST: Discovery) but a good one.

Is the copy of you, you? Or is it a brand new person with the same memories? Would it have ANY memories? Would it have the same consciousness? (Or ANY consciousness?)

Of course, you can always stick to the “David Brin Theory” of teleportation: “Some dude in the future will figure this all out.”

Lazy writers!

(This is why, in my novel, I stick to quantum teleportation of inanimate objects only. That includes quantum communication relays, chunks of asteroids…miniature nuclear bombs…you know, “realistic” things like that.)

And, yes, quantum teleportation is real. Just very, very tiny. For now.

“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!)

Black holes, Hawking radiation, and quantum physics: Feeling dense yet?

Modern physics dictates that, after being consumed, information about this matter should be forever lost to the universe. But a new experiment suggests that there might be a way to use quantum mechanics to gain some insight into the interior of a black hole.
