Can predicting energy levels from quantum systems be done efficiently on conventional computers? New results demonstrate this task is as difficult classically as breaking modern encryption, specifically, solving it quickly would imply a fast method to factor large numbers used in RSA security protocols. This rigorously proves inherent computational limits and validates potential speedups offered by quantum machine learning algorithms.

Predicting quantities related to quantum systems accurately with limited classical information is computationally hard for conventional computers in certain cases. Predicting properties, specifically traces of functions applied to Hamiltonians and density matrices, is difficult using standard computing methods when considering cosine and exponential decay as descriptions of system evolution. Predicting certain properties of quantum systems presents computational challenges for standard computers. The focus lies on ‘Hamiltonian function learning’, whereby algorithms predict characteristics based solely on limited classical information concerning a system’s…
