Chinese researchers have used a 78-qubit superconducting quantum processor to demonstrate that structured random pulses can hold off the chaotic heating that rapidly destroys quantum information. In ...

An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference ...

Quantum computers are alternative computing devices that process information, leveraging quantum mechanical effects, such as ...

Scientists at the Institute of Physics at the Chinese Academy of Sciences have directly ...

Just a few years ago, many researchers in quantum computing thought it would take several decades to develop machines that could solve complex tasks, such as predicting how chemicals react or cracking ...

They combined optical tweezers with metasurfaces to trap more than 1,000 atoms, with the potential to capture hundreds of thousands more. Quantum computers will only surpass classical machines if they ...

Researchers have demonstrated a new way to read Majorana qubits, highly stable but notoriously difficult-to-measure quantum ...

Quantum computers hold great promise for exciting applications in the future, but for now they keep presenting physicists and engineers with a series of challenges and conundrums. One of them relates ...

New pre-print describes codes that “move” logical ancilla qubits up and down to significantly reduce the error rate ...

Quantum computers struggle because their qubits are incredibly easy to disrupt, especially during calculations. A new experiment shows how to perform quantum operations while continuously fixing ...

Scientists have developed a new way to read the hidden states of Majorana qubits, which store information in paired quantum modes that resist noise. The results confirm their protected nature and show ...

Another major quantum computing record has been broken, and by a considerable margin: physicists have now built an array containing 6,100 qubits, the largest of its type and way above the thousand or ...
