🔬 1 Million Physical Qubits Strategy

Google's Willow chip proved exponential error suppression. Their decade-long roadmap focuses on building a 1-million physical qubit machine to generate 1,000 error-corrected logical qubits by 2029, operating as modular 'quantum transistors'.

Derivation & Evidence

Google has officially set a concrete goal to secure 1,000 logical qubits by 2029. According to the report, Google's surface code overhead traditionally requires around a 1,000:1 ratio. Thus, to implement 1,000 logical qubits, they are simultaneously driving expansion for a 1 million physical qubit infrastructure. Their most profound breakthrough hardware currently observable is the 105 physical qubit Willow chip.
