New Codes Could Make Quantum Computing 10 Times More Efficient
Quantum computing is still really, really hard. But the rise of a powerful class of error-correcting codes suggests that the task might be slightly more feasible than many feared. The post New Codes Could Make Quantum Computing 10 Times More Efficient first appeared on Quanta Magazine
In the world of quantum error correction, an underdog is coming for the king. Last week, new simulations from two groups reported that a rising class of quantum error-correcting codes is more efficient by an order of magnitude than the current gold standard, known as the surface code. The codes all work by transforming a horde of error-prone qubits into a much smaller band of “protected” qubits...
