Physicists have achieved a breakthrough by using a 58-qubit quantum computer to create and observe a long-theorized but never-before-seen quantum phase of matter: a Floquet topologically ordered state ...

The decades-long quest to create a practical quantum computer is accelerating as major tech companies say they are closing in on designs that could scale from small lab experiments to full working ...

A quantum computer has reached new heights. The first quantum computer in space is now orbiting Earth on a satellite, scientists report. Launched on June 23, the computer had to be designed to fit in ...

To make some quantum computers larger, and therefore more powerful, we may have to 3D-print them. The purpose of an ion trap is right in its name: it confines ions in place and helps control their ...

Scientists using Google’s quantum processor have taken a major step toward unraveling the deepest mysteries of the universe. By simulating fundamental interactions described by gauge theories, the ...

A device with more than 6000 quantum bits, or qubits, has smashed a previously-held record and is the first step towards building the largest quantum computer yet. Each of these is a neutral caesium ...

The company says it has cracked the code for error correction and is building a modular machine in New York state. IBM announced detailed plans today to build an ...
