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

The low-noise, high-gain properties needed for high-performance quantum computing can be realized in a microwave photonic circuit device called a Josephson traveling-wave parametric amplifier (JTWPA), ...

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 ...

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

Just a few years ago, many researchers in quantum computing thought it would take several decades to develop machines that ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...

When performing calculations in a quantum computer qubits are required. Qubits are the units that enable the computer to ...
