Crystals with iridescence in time instead of space could significantly boost the power of quantum computers; can also be used as frequency combs

"time crystals, defined by their lowest possible energy state which perpetually repeats movements without external energy input, made part of optomechanical system that can adjust the crystal’s properties... radio waves pump magnons into near-absolute 0 Helium-3 superfluid, then pump turned off whereby magnons formed time crystal on top staying in motion up to 108 cycles/ several minutes before fading, whereby time crystal connected itself to nearby mechanical oscillator, adopting same frequency/ amplitude"
