Maxwell ’ s demon and quantum-dot cellular automata

  title={Maxwell ’ s demon and quantum-dot cellular automata},
  author={John Timler and Craig S. Lenta},
Quantum-dot cellular automata ~QCA! involves representing binary information with the charge configuration of closed cells comprised of several dots. Current does not flow between cells, but rather the Coulomb interaction between cells enables computation to occur. We use this system to explore, quantitatively and in a specific physical system, the relation between computation and energy dissipation. Our results support the connection made by Landauer between logical reversibility and physical… CONTINUE READING
