Quantum computing: Superconducting ‘fluxonium’ is the longest lasting qubit ever

Fluxonium qubits might make quantum computer systems extra helpful

A superconducting qubit, or quantum bit, has damaged the file for the way lengthy it will possibly keep its quantum properties. Extending this time will make future quantum computer systems extra helpful.

Step one in constructing a quantum pc is selecting the best way to make its key substances, known as qubits. One widespread selection, championed by analysis labs and trade gamers resembling IBM and Google, is the transmon superconducting qubit. However like all qubits, these can change into ineffective at storing and processing data after a …
