Silicon spin qubits, such as Tunnel Falls, leverage the spin of a single electron to encode information as 0s and 1s. Intel asserts that this approach is superior to other qubit technologies due to its compatibility with transistors, providing a synergistic advantage. These qubits are incredibly small, measuring approximately 50 nanometers by 50 nanometers—up to 1 million times smaller than other qubit types. This miniaturization paves the way for efficient scaling possibilities.
