Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems.

In the previous article titled “The Basics: How Quantum Computers Work and Where the Technology is Heading,” we provided an overview of foundational quantum computing concepts, including qubits ...

Rapid advances in the kind of problems that quantum computers can tackle suggest that they are closer than ever to becoming ...

Fully functional quantum computers remain out of reach, but optimism across the field is rising. At the Q2B Silicon Valley conference in December, researchers and executives ...

Scientists map how quantum computer errors persist and link over time, revealing hidden memory that could reshape error ...

Maria Violaris works on quantum foundations as an academic visitor at the University of Oxford, UK, and on quantum computing at Oxford Quantum Circuits, Reading, UK. Norma G. Sanchez, is the founder ...

Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring millions of dollars into developing a campus to build the world’s first ...

A quantum computer is not limited to this “either/or” way of thinking. Its memory is made up of quantum bits, or qubits—tiny particles of matter like atoms or electrons. And qubits can do “both/and,” ...

The authors declare no competing interests. The research was supported by the Sydney Horizon Fellowship program, the Wellcome Leap Quantum for Bio program, the Australian Research Council, the US ...
