Summary
A Chalmers team said it can execute a broad range of bosonic quantum operations in a single driving cycle instead of several thousand, making some processes more than 1,000 times faster.
The speedup matters because quantum errors accumulate over time; shortening operations reduces exposure to electrical noise, cosmic radiation and overheating that can derail calculations.
The method uses quantum lattice gates with bosonic quantum codes, storing information in microwave fields inside superconducting circuits rather than individual qubits to improve error protection.
Chalmers said the approach should work on existing superconducting platforms and is discussing experimental tests as it builds a 100-qubit quantum computer.
The result, published in Physical Review Letters, targets a key bottleneck in fault-tolerant quantum computing: creating and controlling error-correcting states quickly and reliably.
