⚡ Quantum Brief
IBM CEO Arvind Krishna outlined quantum computing’s success timeline during the World Government Summit in Dubai, stating IBM will assess viability by 2029—when error-corrected systems could surpass classical supercomputers. Krishna emphasized quantum’s potential to revolutionize industries like drug discovery and logistics but stressed practical applications remain years away, pending hardware advancements and error mitigation breakthroughs. The CEO highlighted IBM’s $20 billion investment in quantum and AI, framing it as a long-term bet despite skepticism, with interim milestones tied to qubit stability and algorithm efficiency. He noted governments and enterprises must collaborate to accelerate adoption, citing partnerships with global research labs as critical to overcoming technical hurdles like decoherence and scalability. Krishna warned against overhyping near-term gains, urging patience as quantum’s true impact—like classical computing’s evolution—will unfold gradually over decades, not years.
