Quantum computers, systems that process information leveraging quantum mechanical effects, are expected to outperform classical computers on some complex tasks. Over the past few decades, many ...

Two companies that are racing to develop a photonic quantum computer using photonic qubits are PsiQuantum, based in Palo Alto ...

A University of Sydney quantum physicist has developed a new approach to quantum error correction that could significantly ...

Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical ...

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. Imagine a ...

For the past year, I kept bringing the same story to my editor: quantum computers are on the edge of becoming useful for scientific discovery. Of course, that has always been the goal. The idea of ...

Quantum processors operate in environments engineered to eliminate nearly all external interference. That just might make ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.
