What Is a Spin Qubit? One Electron, Two States | Silicon Qubits, Superposition & Quantum Computing
What is a spin qubit? Brandon Severin, CEO of Conductor Quantum, explains it like this: put a single electron in a magnetic field and it behaves like a tiny compass needle with two orientations, spin-up and spin-down.
Those are your 0 and 1. By isolating that electron on a gated silicon device and hitting it with precise pulses, you can flip, hold, and combine those states (superposition).
He also explains that spin qubits are built with the same fabrication tech as classical transistors. If we can print tens of billions of transistors on a modern NVIDIA or Apple chip, the same infrastructure could eventually produce comparable numbers of spin qubits, because each qubit is essentially one electron you can address and control.
