>the secret breakthrough was apparently something to do with optimizing some sort of quantum tunneling. I don't understand the particulars but we're apparently playing with the underlying structure of time. we are able to tunnel through billions of questions and receive answers immediately.

"They are using time dilation (for instance, by sending a computer into orbit at very high speeds or near a strong gravitational field) to perform computations that take longer from our perspective but are completed more quickly for the computer itself. This isn't time travel, but it's a way to exploit relativistic effects for computational advantage."

"In other words, you send this signal into the CTC.
Because of the nature of a CTC, the signal will eventually loop back to a point in spacetime that is in your past. Now, you set up a detector to receive the signal when it emerges from the CTC at that earlier time.
This received signal would be the result of your computation, arriving before you even initiated the computation from our perspective."
