AI-summarised brief · reviewed before publication

Mathematician Gil Kalai discusses his skepticism about scalable quantum computing, citing correlated noise and complexity-based limits as potential roadblocks. He explains two main arguments behind his theory, including the possibility of correlated errors in entangled qubits. Kalai's conjectures can be tested experimentally with NISQ devices, and he hopes the community will evaluate bold claims critically, considering the implications for the future of quantum research and potential scientific insights if quantum computing ultimately fails to deliver.
