: Significant progress has been reported by teams like Google Quantum AI , which demonstrated that increasing the number of physical qubits in a surface code can indeed suppress logical error rates. 2. Scaling the Distance
: Transitioning from a Distance-3 code (basic protection) to Distance-5 and beyond. : Significant progress has been reported by teams
The Road to Fault Tolerance: Key Milestones in Quantum Error Correction The Road to Fault Tolerance: Key Milestones in
: Without this scalability, we cannot drive logical error rates down to the 10-810 to the negative 8 power 10-1210 to the negative 12 power levels required for useful commercial algorithms. 3. Implementing Fault-Tolerant Gates Milestone 2 | Google Quantum AI : Significant progress has been reported by teams
The first critical milestone for any QEC system is the "breakeven point." This is the threshold where a —an abstract unit made of many physical qubits—actually performs better than the best physical qubit within it.
