The central technical result is a quantum error-correcting code built on the Face-Centered Cubic (FCC) lattice — the densest possible packing of spheres in three dimensions, the arrangement at the ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

Subscribe to our newsletter for the latest sci-tech news updates. In recent years, quantum computers have begun to handle double-digit quantum bits, or qubits. However, many essential applications ...

The researchers have proven PLANAR's effectiveness on surface codes under particular noise conditions and plan to adapt it for non-planar graphs with finite genus, opening the door to broader use in ...

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 ...

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 ...
