A processor exposed to heat can compute universally or be entirely mimicked by a standard computer, determined solely by what information is saved about energy changes during idle periods. Retaining just confirmation of any energy transfer unlocks polynomial overhead universal computation; erasing this record limits processing power to classical simulation. This establishes an exact boundary, defined by relaxation and coherence times alongside excited-state population, previously lacking in classifying quantum behaviours.
Researchers Link Environmental Records to Universal Quantum Computation
A processor exposed to heat can compute universally or be entirely mimicked by a standard computer, determined solely by what information is saved about energy changes during idle periods. Retaining just confirmation of *any* energy transfer unlocks polynomial overhead universal computation; erasing this record limits processing power to classical simulation. This establishes an exact boundary, defined by relaxation and coherence times alongside excited-state population, previously lacking in...
