単層カーボンナノチューブ（SWCNT）量子ビット

Harnessing single-walled carbon nanotubes as qubits for next-generation quantum computing

Abstract: Single-walled carbon nanotubes (SWCNTs) are emerging as a platform for qubits, offering long spin coherence through minimal nuclear-spin noise and strong one-dimensional confinement. This article reviews the physical mechanisms enabling SWCNT qubits – from spin–orbit coupled valley-spin states to quantum dot formation – and discusses their adv…
