Imperfect timekeeping to eventually fundamentally limit quantum computers and any large-scale algorithms they run

"with quantum computers, precise timing is more essential than with conventional computers, as they exploit bizarre behavior of tiny particles such as atoms, electrons, and photons to process information... changing quantum state in quantum computer corresponds to rotation in abstract high-dimensional space... to achieve desired state, rotation must be applied for a very specific period of time—otherwise you turn the state either too little or too far... could be mitigated by designing clever error correction protocols"
