Quantum Computers Aren't Useless. You Just Don't Know How to Use Them.
Into the Impossible With Brian Keating
About
Sabine Hossenfelder says quantum computers are only useful for breaking codes. She's wrong — and my undergraduates are building the proof. What's happening in my lab right now has nothing to do with cryptography, and everything to do with the future of AI.
I'm a cosmologist at UC San Diego teaching undergraduates to build, program, and eventually launch quantum computers — possibly to the Moon via Artemis!
We cover: why Sabine's code-breaking verdict misses the real story, how free tools like Quantum Rings are closing the education gap Sabine thinks is a hardware problem, why Q-Day just got moved up to 2029, what my students are actually doing with quantum computers in my lab, and why the next generation of quantum physicists won't need a billion-dollar facility to train.
The bottleneck isn't the hardware. It's what we're teaching — and who we're teaching it to.
