Quantum computing has a crucial weakness that may severely delay, if not kill outright, its chances of becoming a way of running algorithms that classical computers cannot handle: its susceptibility...

Many applications require quantum processors with millions of quantum bits. Today’s prototypes merely come up with a few of these compute units. At some point, the number of signal...

The key takeaway from the recent NIST announcement is that the NIST algorithms finally bring clarity and certainty to the business community as they transition from algorithms such as RSA...

To start to do anything useful with quantum computers, we need to reach the million-qubit scale. It’s a monumental task but not an impossible one with the right engineering...

For 25 years, QEC researchers have largely focused on mathematical strategies for encoding qubits and efficiently detecting errors in the encoded sets. Only recently have investigators begun to address...

At Innsbruck, Austria, a team of experimental physicists has now implemented a universal set of computational operations on fault-tolerant quantum bits for the first time, demonstrating how an algorithm can...
