One of the biggest challenges for quantum computers is the incredibly short time that qubits can retain information.
A new qubit from Princeton University lasts 15 times longer than industry standard versions in a major step towards large-scale, fault-tolerant quantum systems.
The process of getting the design from the lab bench to the chip foundry is complicated and it is unclear if companies engaged in quantum computing will switch to this new qubit architecture any time soon.
Still, the research has made dramatic progress on one of the biggest challenges holding back superconducting quantum computers.
