But quantum supremacy is not a single, sweeping victory to be sought—a broad Rubicon to be crossed—but rather a drawn-out series of small duels. It will be established problem by problem, quantum ...

It's time to run your errands, and you've got multiple stops to make. From your house, you have to hit the supermarket, the gas station, and the hardware store, all before returning home. Assuming you ...

The quest for "quantum supremacy" – unambiguous proof that a quantum computer does something faster than an ordinary computer – has paradoxically led to a boom in quasi-quantum classical algorithms. A ...

Let s(0), s(1), ... be a given sequence, and define $s(n) = \overline{s(-n)}$ for $n < 0$. If ∑ ∑ ξ̄nξms(m - n) ≥ 0 holds for all finite sequences (ξn)n ∈ ...
