In the fast-evolving world of quantum computing, one of the biggest hurdles isn’t how fast calculations can be done—it’s how long you can hold onto the delicate quantum information in the first place.

WEST LAFAYETTE, Ind. — Caltech president and pioneering physicist Thomas Rosenbaum, an expert in the promising field of quantum physics, will join Purdue University President Mung Chiang in April for ...

When a singer belts out a tune while a guitar player strums along, sound waves travel through the air, driving collective oscillations of the molecules within. Meanwhile, at the quantum level, ...

A team of Caltech scientists has fabricated a superconducting qubit on a chip and connected it to a tiny device that scientists call a mechanical oscillator. Essentially a miniature tuning fork, the ...

Caltech and Oratomic researchers have proposed a design showing that a quantum computer capable of breaking RSA-2048 encryption could be built with only 10,000–20,000 physical qubits, instead of the ...

Laying the groundwork for quantum communication systems of the future, engineers at Caltech have demonstrated the successful operation of a quantum network of two nodes, each containing multiple ...

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 ...

Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining ...

Researchers have invented a new method by which classical computers can measure the error rates of quantum machines without having to fully simulate them. Quantum ...
