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 ...

For decades, physicists believed that even the strangest quantum objects had a hard limit on how strongly their behaviour could be linked across time. No matter how quantum a system was, there was ...

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 ...

Scientists have built a new kind of molecular qubit that could help connect quantum computers over existing telecommunications technology — laying the foundation for a future quantum internet. The new ...

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 ...

Following up on Microsoft’s announcement of a qubit based on completely new physics, Amazon is publishing a paper describing a very different take on quantum computing hardware. The system mixes two ...

Scientists demonstrate a new quantum chip architecture for suppressing errors using a type of qubit known as a cat qubit. Scientists based at the AWS Center for Quantum Computing on Caltech's campus ...

French quantum computing startup Alice & Bob SAS today announced a significant advancement in cat qubit technology to reduce errors in quantum computers. Named after the Schrödinger’s cat thought ...

Meet the team Left to right are Yu Yang, Matteo Fadel, Yiwen Chu and Igor Kladarić. They were the main researchers at ETH Zurich who created the groundbreaking mechanical qubit. (Courtesy: Yu Yang/ETH ...
