ARMONK, NY — IBM researchers announced a quantum computing breakthrough Wednesday that industry experts called the most significant advance in the field in five years: the Eagle-Q processor, featuring 1,024 qubits, maintained coherent quantum operation for 127 seconds — shattering the previous record of 12 seconds and crossing the threshold many theorists have identified as necessary for commercially useful quantum computation.
The achievement was made possible by a new error-correction architecture that addresses the fundamental challenge of qubit decoherence — the tendency of quantum states to collapse when they interact with their environment.
Real-World Applications
IBM said the processor had already been used to simulate molecular interactions relevant to drug discovery and to optimise logistics problems involving 50,000 variables — tasks that would take classical supercomputers years to solve.
"We are not claiming quantum supremacy in all domains," said Dr Dario Gil, IBM's head of research. "But we are saying that for specific classes of problems, the era of practical quantum advantage has arrived."
The announcement immediately affected markets, with shares in encryption companies falling sharply on concerns about the long-term implications for current cybersecurity standards. NIST confirmed it was accelerating the timeline for post-quantum cryptography standards.
