IBMはグラフェンでプロセッサを制作、今のところアナログCPU(デジタルでない)に限定。
デジタルCPUよりも機械学習や脳シミュレーションに適合する可能性もあるが、計算効率は悪くなる。

「Computation is based on the spatial and temporal positions of the
pulses. “This is sort of the fundamental way neurons communicate
with other neurons,” he says.」

「Since Graphene is widely known for its high carrier mobility and low noise
features, it is highly recommended as a field-effect transistor. A Graphene-based
integrated circuit can handle frequencies up to 10 GHz. The transistors printed
on flexible plastic can operate at 25 gigahertz. A simple 2-inch of Graphene sheet
can establish a processor using 100 GHz transistors.」

「“We don't want to make them the way the semiconductor industry does now. Our step, which is most critical for roll-to-roll printing, is ready.”」
