A new Nature critique questions Microsoft’s quantum computing research, raising doubts about a key study behind its goal of building a working quantum computer by 2029.

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.

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

A peer-reviewed critique of Majorana 1 claims Microsoft did not conclusively demonstrate a working topological qubit. Microsoft disagrees.

The approach is known for high accuracy, but scaling it up while preserving that accuracy is technically difficult. Helios uses barium ions in what is called a quantum charge-coupled device, or QCCD, architecture. A useful way to picture it is as a tiny quantum railway.

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.

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.

A public-private partnership in the Mountain West announced new results today that mark steady progress toward the Department of Energy's goal of fault-tolerant quantum computing, systems large and reliable enough to solve complex problems.

The US has unveiled a technological strategy to build and operate a specialized quantum
