Quantum Links in Time and Space May Form the Universe’s Foundation

In November, construction workers at the Massachusetts Institute of Technology came across a time capsule 942 years too soon. Buried in 1957 and intended for 2957, the capsule was a glass cylinder filled with inert gas to preserve its contents; it was even laced with carbon-14 so that future researchers could confirm the year of burial, the way they would date a fossil. MIT administrators plan to repair, reseal and rebury it. But is it possible to make it absolutely certain that a message to the future won’t be read before its time?

You’re kidding yourself if you think that quantum encryption cannot be cracked.

Why do you think quantum cryptography can be cracked, mollwollfumble?

Why do you think quantum cryptography can be cracked, mollwollfumble?

Two reasons, well three. One is that it’s trivially easy to interfere with the quantum encrypted signal in such a way that only garbled information of no value gets through, which makes it necessary for the sender to resend a copy of the original, and having multiple copies of the same message makes cracking it by the intecepter relatively easy.

A second is that anything that can be coded can be cracked if you throw enough resources at it. It’s said that one time pads can’t be cracked, but they can if you can figure out the algorithm used to produce the one time pad.

one time pads can’t be cracked if no algorithm is used. so that alone falsifies your argument.
