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 ...

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 ...

Online data is generally pretty secure. Assuming everyone is careful with passwords and other protections, you can think of ...

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 ...

With around 26,000 qubits, the encryption could be broken in a day, the researchers report in a paper submitted March 30 to arXiv.org. Another prevalent form of encryption, RSA–2048, would require 100 ...

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 ...
