Wormholes, Superfast Computations, and Selivanov’s Theorem
Abstract
While modern computers are fast, there are still many practical problems that require
even faster computers. It turns out that on the fundamental level, one of the main factors limiting
computation speed is the fact that, according to modern physics, the speed of all processes is
limited by the speed of light. Good news is that while the corresponding limitation is very severe
in Euclidean geometry, it can be more relaxed in (at least some) non-Euclidean spaces, and,
according to modern physics, the physical space is not Euclidean. The differences from Euclidean
character are especially large on micro-level, where quantum effects need to be taken into account.
To analyze how we can speed up computations, it is desirable to reconstruct the actual distance
values – corresponding to all possible paths – from the values that we actually measure – which
correspond only to macro-paths and thus, provide only the upper bound for the distance. In our
previous papers – including our joint paper with Victor Selivanov – we provided an explicit
formula for such a reconstruction. But for this formula to be useful, we need to analyze how
algorithmic is this reconstructions. In this paper, we show that while in general, no reconstruction
algorithm is possible, an algorithm is possible if we
impose a lower limit on the distances between steps in a path. So, hopefully, this can help to
eventually come up with faster computations.
