Milestone Needed To Be Achieved In Quantum: Computing With Error Correction

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.

: Error correction itself requires additional gates and measurements, which can introduce more errors. The first critical milestone for any QEC system

The Road to Fault Tolerance: Key Milestones in Quantum Error Correction Scaling the Distance

: 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.

: 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
