Starling System: First Official FTQC Target
IBM has introduced a Bivariate Bicycle qLDPC code to drastically reduce physical qubit overhead. By 2029, their 'Starling' system aims to deliver 200 Logical Qubits capable of 100 million gate operations, marking their official entry into the Fault-Tolerant era.
Derivation & Evidence
This is the target value for IBM's 'Starling' system (2029). According to the report's derivation logic, the Bivariate Bicycle qLDPC code used to generate 12 logical qubits requires 288 physical qubits. Therefore, achieving 200 logical qubits mathematically requires approximately 4,800+ physical qubits (a staggering 24:1 overhead ratio).
