Investment and new milestones in quantum computing are bringing the prospect of an ultra-powerful computer that can crack any code closer to reality.

Alphabet Inc.’s Google and International Business Machines Corp. are racing to increase the number of qubits — the quantum equivalent of bits that encode data on classical computers — on a quantum chip. Firms like Canada’s D-Wave Systems Inc. and French startup Alice&Bob are offering quantum computing services to clients that want broad processing power to solve complex problems.
