Microsoft has unveiled Majorana 2, a new topological quantum processor that uses lead-based materials, delivers longer qubit lifetimes, and supports the company's goal of scalable quantum computing by 2029.

Microsoft Corp. has announced an updated chip for quantum computing called Majorana 2 that’s said to be 1,000-times more reliable in terms of qubit stability. According to the company, it opens the door to a much faster path towards building commercially viable quantum computers.

Microsoft said AI helped speed Majorana 2 development, adding to growing concerns about when quantum computers could threaten Bitcoin's cryptography.

Microsoft on Tuesday unveiled a new quantum computing chip that it redesigned with the help of AI, saying it now believes it will have commercially

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

Digital secrets are protected by encryption, which converts meaningful data into an unintelligible form. If quantum computers could unscramble current encryption, they could expose highly sensitive data. Useful, perhaps, for nation states tracking terror cells or spying on strategic competitors – but bad news for everyone else.

The government can handle more risk than you might be comfortable with.
