Building a Quantum Computer at a Really, Really Low Temperature
If even a single photon comes in and interacts with our qubits, you've lost it. You've broken the coherence of the entangled qubits that you started with. And there's a lot of photons out there in the universe. Everything around us is glowing because it has a temperature. That's why you need to build a quantum computer at a really, really, really low temperature. But what really strikes me about quantum computer builders like Michelle is that they don't spend a lot of time worrying about the weirdness of the quantum world. The mysteries of quantum mechanics are not something that I consider every day," says Sean Carroll.
