#TimeTravelAuthors #DaySeven : What does your time machine look like?
That's a little complicated. It's not exactly a single machine.
After some of her colleagues demonstrated a theoretical wormhole using quantum entanglement, Dorothy worked to make the theoretical practical.
Using a brand new quantum computer the University acquired, she was able to consistently create a wormhole. This is a quantum wormhole. Too small to see, but large enough for information to pass through.
She then created a device that could network with the quantum computer. It looks like a typical tablet computer, and she calls it her QPad. She attaches the QPad to her laptop (a traditional binary computer), and can connect to the quantum computer from anywhere, and is able to create a wormhole from wherever she is to her lab at MIT.
She was doing this one afternoon from her apartment in Ashmont. What she didn't know is that in about the year 3050, a more advanced quantum computer, being controlled by a certain Wizard, in roughly the same place as hers, had interfaced with her QPad. So instead of connecting to a computer ten miles away, she connected to one over a thousand years away.
And this computer could stabilize and enlarge the wormhole with a bit of exotic matter. So, when she started it up, instead of a subatomic wormhole forming, a ten feet tall, blue swirling vortex appeared in her living room.
