## Technical Deep Dive
Intel's quantum efforts are primarily focused on the development of silicon spin qubits. This approach uses the spin of individual electrons in silicon as quantum bits. Key aspects of Intel's silicon qubit technology include:
1. Fabrication Process: Intel leverages its advanced 300mm silicon fabrication facilities to create silicon spin qubits. This allows them to potentially manufacture quantum chips using processes similar to those used for classical semiconductor devices.
2. Spin Qubit Architecture: Intel's qubits are created by trapping individual electrons in quantum dots formed in silicon. The spin of these electrons (up or down) is used to represent quantum states.
3. "Hot Qubits": In 2020, Intel announced a breakthrough allowing their silicon spin qubits to operate at temperatures up to 1 Kelvin. While still very cold, this is significantly warmer than the millikelvin temperatures required by superconducting qubits. This could potentially simplify the cryogenic systems needed for quantum computers.
4. Scalability: Intel argues that silicon spin qubits could be more scalable than other qubit technologies due to their small size and compatibility with existing semiconductor manufacturing processes.
Intel's work on quantum control systems is another crucial aspect of their quantum strategy:
1. Horse Ridge Cryogenic Control Chip: Introduced in 2019, Horse Ridge is a cryogenic control chip designed to simplify the complex control electronics required for quantum computers. It operates at about 4 Kelvin, much warmer than the qubits themselves.
2. Horse Ridge II: An updated version announced in 2020, featuring enhanced capabilities including the ability to manipulate and read qubit states.
