[Music] There are many ways to build a quantum computer. Each uses cubits, quantum bits as its core building block. But no matter the method, all cubits, whether superconducting cubits, trapped ions, neutral atoms or photons, share the same challenge.They're fragile and extremely sensitive to noise. Today's Qbits remain stable for only a few hundred operations. But solving meaningful problems requires trillions of operations.The answer is quantum error correction. Measuring disturbs a cubit which destroys t ...
