Aalto University physicists in Finland have set a new benchmark in quantum computing by achieving a record-breaking millisecond coherence in a transmon qubit — nearly doubling prior limits. This ...

On July 8, 2025, physicists from Aalto University in Finland published a transmon qubit coherence measurement in Nature Communications that dramatically surpasses previous scientifically published ...

A Princeton team built a new tantalum-silicon qubit that survives for over a millisecond, far surpassing today’s best devices. The design tackles surface defects and substrate losses that have limited ...

TOKYO--(BUSINESS WIRE)--Toshiba Corporation (Toshiba) has confirmed a breakthrough technology that promises to advance progress toward the development of higher-performance quantum computers through ...

For more than a decade, researchers have primarily used transmon qubits in their efforts to build quantum computers. Another type of superconducting qubit, known as a fluxonium qubit, originated more ...

Superconducting fluxonium qubits provide a promising alternative to transmons on the path toward large-scale superconductor-based quantum computing due to their better coherence and larger ...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...

Researchers at Toshiba Corporation (TOKYO: 6502) have achieved a breakthrough in quantum computer architecture: the basic design for a double-transmon coupler that will improve the speed and accuracy ...

A Princeton team has reported their new qubit lasts for over 1 millisecond, three times longer than the best ever reported in a lab setting, and nearly fifteen times longer than the industry standard ...
