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.

Quantum computing is a revolutionary form of computing that uses the principles of quantum mechanics to perform calculations that would be infeasible or impossible for classical computers. Unlike classical computers, which use bits as the basic unit of ...

Four decades ago, physicists were theorizing that the mind-bending mechanics of quantum physics could be harnessed to make a new kind of computer that’s exponentially more powerful than conventional machines.

One order directs federal agencies to work with private companies and universities to deliver a quantum computer capable of supporting scientific research by 2028. The Department

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.

This year, the company is laying the groundwork to turn quantum computing into a fully-fledged, scalable business from an expensive science project.

On May 21, the U.S. Commerce Department announced it would give a total of $2 billion in grants to nine companies at the bleeding edge of quantum computing technology, including I
