We analyse the pros and cons of analog versus digital computation in living cells. Our analysis is based on fundamental laws of noise in gene and protein expression, which set limits on the energy, time, space, molecular count and part-count resources needed to compute at a given level of precision. We conclude that analog computation is significantly more efficient in its use of resources than...

The realization of effective Hamiltonians featuring many-body interactions beyond pairwise coupling would enable the quantum simulation central models underpinning topological physics and computation. We overcome crucial limitations perturbative Floquet engineering discuss highly accurate a purely three-body Hamiltonian in superconducting circuits molecular nanomagnets.

Molecular computing is a new multidisciplinary area of research concerned with design, and theoretical and empirical understanding of computing gleaned from nature. It aims at the implementation of algorithms in molecular hardware, e.g. using DNA molecules and enzymes. The main advantages of the molecular computing lie in the possibility to obtain a massive parallelism of computation and associ...
