A quantum bit, otherwise known as a qubit, is the basic unit of data in quantum computing. Like a binary bit in classical computers, as it can store information, but behaves very differently thanks to ...

Caltech scientists have built a record-breaking array of 6,100 neutral-atom qubits, a critical step toward powerful error-corrected quantum computers. The qubits maintained long-lasting superposition ...

Quantum computers will need large numbers of qubits to tackle challenging problems in physics, chemistry, and beyond. Unlike classical bits, qubits can exist in two states at once—a phenomenon called ...

This image shows 6,100 cesium atoms trapped by highly focused laser beams called optical tweezers. The width of the circle is about one millimeter. Quantum computers will need large numbers of qubits ...

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.

Here’s what you’ll learn when you read this story: Creating quantum entanglement from scratch can be tricky business, so researchers are exploring ways that entangled pairs can “share” these states ...

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 ...

Richard Feynman, the iconic physicist and one of the progenitors of quantum computing, famously said in 1981: “Nature isn’t classical, dammit, and if you want to make a simulation of nature, you’d ...

Caltech physicists report they have created the largest qubit array assembled to-date: 6,100 neutral-atom qubits trapped in a grid by lasers. Previous arrays of this kind contained only hundreds of ...

On Thursday, Microsoft’s Azure Quantum group announced that it has settled on a plan for getting error correction on quantum computers. While the company pursues ...
