it's only the thin coating surrounding the mass that is made of a gold/platinum alloy, not the entire cube. So it is NOT 2kg of gold...
actually gold coatings are used quite a lot for these things.

They have a mass floating freely in space, and surrounding it is this gold/platinum coat, that never touches it, it just flies around it and has microthrusters to keep it away from the central mass. This gold/platinum coat is shielding the mass from some external influences, like the solar magnetic field, so that the central mass only feels the influence of the gravitational waves.

Apparently you missed the whole reason why quantum cryptography is radically different:
It is IMPOSSIBLE to duplicate the quantum key or the quantum message exactly.
So Michaels qubits are different from the one Bob sent AND there are ways for Alice to find out that they are different, so she knows eavesdropping has occurred.

It's a bit like making a copy of a letter
- that self destructs when it is copied or read
- that looks different depending on the light you use to scan it/read it (for example rgb(125,54,74))
- and the copy you make will again be spread over the different frequencies in a random way.

So some of it will only be visible again if it is viewed under light of color rgb(245,45,7), while other parts can only be seen under light rgb(45,4,48)
So the end result of your copy will NOT be the original.
When Alice wants to read the letter, she uses the frequency that Bob told her to use. If that color wasn't rgb(125,54,74), then Michael wasn't able to copy the message anyway. But even if Michael already used the correct color to make the copy, the copied version will only have part of the message in the correct color.

So Alice uses rgb(125,54,74), and then notices that most of the words on the letter are still missing! En thus she knows that this is not the original one, but a copy!
