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 ...

Scientists say they have reached "a critical inflection point" after developing a technology that makes silicon-based quantum processors more viable. Quantum computing company Equal1 has created a ...

A physical qubit only lasts for billionths of a second, so its lifetime isn't long enough for the "decoder" circuitry of the quantum machine to read its information. Also: AI agents might be the ...

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 ...

Google's 2019 experiment involved a 54-qubit processor carrying out a series of random operations. Although the output would be fundamentally useless, the researchers estimated that it would take ...

On one hand, charge noise in the qubit operation process is deeply suppressed. Charge noise has long been a troublesome issue in the field of quantum control, acting like an "invisible ...

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 ...
