Ironically, quantum computers have the opposite problem; coherence times for QC qubits are still less than a second: there is not yet a way to store qubits for even one second.
> If quantum information is never destroyed – and classical information is quantum information without the complex term i – perhaps our [RAM] states are already preserved in the universe; like reflections in water droplets in the quantum foam
According to the "Air gap malware" Wikipedia article's description of GSMem, the x86 RAM bus can be used as a low power 3G antenna. And, HDMI is an antenna, and, Ungrounded computers leak emanations to the ungrounded microphone port on the soundcard.
