4+ day, 3+ hour ago   (173+ words) Muhammad Ahsan Shakeel from Management Sciences and colleagues have shown that an amplitude-inspired quantum feature map maintains one hundred per cent test accuracy up to an error probability of 0.10 across depolarizing, bit-flip and phase-flip noise channels. Other tested feature maps…...

3+ week, 3+ day ago   (661+ words) On twenty-qubit Clifford+T circuits, a new method removes double the number of computational steps compared with existing techniques, even when applied to problems five times more complex than those used during its development. By integrating established simplification rules into…...
