Rigetti Computing (NASDAQ: RGTI), a developer of quantum computing systems, went public by merging with a special purpose ...

The new method encodes quantum information onto an antimony atom, which has eight possible states that enable data to be more safely stored than in a standard two-state qubit, or quantum bit. The ...

The new method encodes quantum information onto an antimony atom, which has eight possible states that enable data to be more safely stored than in a standard two-state qubit, or quantum bit.

The team used timed pulses and a form of synthetic light to reduce errors and improve the accuracy of their quantum computer.

“If the qubit is a spin, we can call ‘spin down’ the ‘0’ state, and ‘spin up’ the ‘1’ state. But if the direction of the spin suddenly changes, we have immediately a logical ...

To improve the situation, MIT researchers and researchers worldwide have continually focused on improving qubit performance. In new work, using a superconducting qubit called fluxonium ...

In their experiments, Chen, Zhu and their colleagues used classical decoding to extract and stabilize the quantum order in their 54-qubit system that was masked by noise. They found that this ...

Google revealed progress in creating a 105-qubit chip, part of its roadmap to develop a quantum system with 1 million qubits. This news led to a great exchange between Sundar Pichai and Elon Musk with ...

The device, which cools qubits to record low temperatures, is composed of two qubits—one hot (top right) and one cold (bottom right)—which cool a third, target qubit (bottom left). Powered by heat ...

The new quantum refrigerator – the square object in the centre of the qubit in the image – is based on superconducting circuits and powered by heat from the environment. Researchers at the ...
