Gil Kalai’s Argument Against Quantum Computers | Quanta Magazine

The mathematician Gil Kalai believes that quantum computers can't possibly work, even in principle.

"Today, Kalai, a mathematician at Hebrew University in Jerusalem, is one of the most prominent of a loose group of mathematicians, physicists and computer scientists arguing that quantum computing, for all its theoretical promise, is something of a mirage. Some argue that there exist good theoretical reasons why the innards of a quantum computer — the “qubits” — will never be able to consistently perform the complex choreography asked of them...
