The alleged dangers of AI have been shoved down people’s throats for years, led by doomerism about it eliminating human jobs or wiping out mankind itself. Yet, there are far fewer discussions about how scientists are on the cusp of a breakthrough more powerful and much more worrying: Quantum computing.

Quantum computing has long been the technology that always seems to be 10 years away. Now, one of the most senior technology executives in the world says the wait is almost over. Amazon's (AMZN) top artificial intelligence (AI) executive has put a firm timeline on when the world will see its first working quantum computer that businesses can use.

RIKEN’s ROQUO supercomputer shows why hybrid quantum computing depends first on classical GPU, networking, cooling, and software infrastructure.

A new federal initiative to build a quantum supercomputer could transform everything from encryption to drug discovery, creating the next wave of winners and losers.

The point at which quantum computers outperform classical ones will arrive. The question is who controls the infrastructure when it does.

The company has been touting its quantum technology for years, but some experts say these claims just don’t pass muster

In a laboratory in Broomfield, Colorado, 98 atoms are suspended in midair, held in place by electric fields and cooled to temperatures close to absolute zero.

For much of the past two years, investors treated quantum computing as a single investment theme. Whether a company pursued trapped-ion systems, superconducting qubits, quantum annealing, or photonic architectures mattered less than the fact that it was associated with quantum computing.
