Just as the sound of a guitar depends on its strings and the materials used for its body, the performance of a quantum computer depends on the composition of its building blocks. Arguably the most ...
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 ...
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 ...
On July 8, 2025, physicists from Aalto University in Finland published a transmon qubit coherence dramatically surpassing previous scientifically published records. The millisecond coherence ...
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 ...
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 ...
