Scientists have developed an exact approach to a key quantum error correction problem once believed to be unsolvable, and have shown that what appeared to be hardware-related errors may in fact be due ...

Those questions form the core of computational complexity ... amount of time by a classical computer. Precise version: EXP contains all the previous classes — P, NP, PH, PSPACE and BQP. Researchers ...

One supergraph will bundle many smaller graphs into ... machines run by different companies. Apollo’s vision is that the idea of a supergraph abstracts away all of that complexity.
