Your bank could give you a quantum keyfob. All of your encrypted transactions are now entangled, so you know that nobody has spied on them: the act of observation modifies the result.

It sounds like you're describing quantum cryptography, which doesn't require a quantum computer and in fact already exists commerically.

To be honest it sounds like they’re describing the plot of the next mission impossible film rather than anything that exists in our reality.
