The Role of Correlation in the Operation of Quantum-dot Cellular Automata
Geza Toth, Craig S. Lent
Quantum-dot Cellular Automata (QCA) may offer a viable alternative of traditional transistor-based technology at the nanoscale. When modeling a QCA circuit, the number of degrees o…
Quantum Cellular Neural Networks
Geza Toth, Craig S. Lent, P. Douglas Tougaw +5
We have previously proposed a way of using coupled quantum dots to construct digital computing elements - quantum-dot cellular automata (QCA). Here we consider a different approach…
Quasi-adiabatic Switching for Metal-Island Quantum-dot Cellular Automata
Geza Toth, Craig S. Lent
Recent experiments have demonstrated a working cell suitable for implementing the Quantum-dot Cellular Automata (QCA) paradigm. These experiments have been performed using metal is…
Conductance Suppression due to Correlated Electron Transport in Coupled Double-dots
Geza Toth, Alexei O. Orlov, Islamshah Amlani +3
The electrostatic interaction between two capacitively-coupled metal double-dots is studied at low temperatures. Experiments show that when the Coulomb blockade is lifted by applyi…
