Researchers at the Swiss Federal Institute of Technology (ETH) in Zurich have developed the first-ever fully functional mechanical qubit. This incredible quantum innovation is a two-in-one system ...

A fault-tolerant quantum computer could be here by 2030, thanks to an invention called the "cat qubit," named after the famous Schrödinger's cat thought experiment, in which a cat locked in a box ...

A Chinese group led by China Telecom Quantum Computing Group has unveiled Xiaohong-504, a 504-qubit quantum computing chip, and Tianyan-504 superconducting quantum computer. The achievement can be ...

Among the current challenges with creating quantum computers is that the timespan that a singular qubit remains coherent is quite limited, restricting their usefulness. Usually such qubits consist ...

Thanks to an improved processor, Google's team found that increasing the number of hardware qubits dedicated to an error-corrected logical qubit led to an exponential increase in performance.

BERKELEY, Calif.,– Quantum-classical computing company Rigetti announced the launch of its flagship 84-qubit Ankaa-3 system featuring a hardware redesign. Rigetti ...

Key design features include: – Cryogenic Hardware Design: Enhanced thermalization and shielding reduce noise and support the development of larger qubit systems. – Josephson Junction ...

This includes a new cryogenic hardware design to reduce the amount of metal at the refrigerator’s coldest stage, increasing efficiency and reducing the cost per qubit, and an improved qubit chip ...
