A key challenge for computation is solving problems in high
dimensions. Two classic proposals for tackling high dimensional
problems are the Bethe approximation, or "belief propagation", and
the quantum Fourier transform. Tensor networks offer a...
In quantum information theory (QIT), arguments often rely —
sometimes implicitly — on the assumption that a given process can
be repeated identically and independently many times. However,
establishing the stochastic independence of repeated...
