Ultimate bounds on the maximum operating frequency of networks of quantum dot cellular automata devices have yet to be established. We consider the adiabaticity of such networks in the two-state approximation where clocking is achieved via modulation of the inter-dot tunneling barriers. Estimates of the maximum operating frequency that would allow a 99% probability of observing the correct logical output are presented for a subset of the basic components used in QCA network design.

Low-Energy Eigenspectrum Decomposition (LEED) of Quantum-Dot Cellular Automata Networks
This work presents a methodology for understanding the spectrum of the full network in terms of contributions from components of the network, and shows that important features of the low energy spectrum can be attributed to specific critical components, and presents one scheme for decomposing the network into these components.
Population congestion in 3-state quantum-dot cellular automata
3-state QCA is investigated in the regime in which congestion is significant and the extent to which such effects can be mitigated for SiDB devices is determined, proposing that while SiDB-based QCA wires may be achievable depending on limitations of inter-dot tunneling, higher density devices may need to be replaced by more architecture specific implementations unless net-neutral variants of SiDB QCA devices can be demonstrated.
Optimal demultiplexer unit design and energy estimation using quantum dot cellular automata
This article proposed and analyzed a simple and optimized QCA-based single-layered demultiplexer only using two majority gates, one inverter and two clocks, which has a complexity of 21 QCA cells and area usage of 33.33%.
Zwitterionic Mixed-Valence Species for the Design of Neutral Clocked Molecular Quantum-Dot Cellular Automata.
DFT results clearly demonstrate that 1 can display simultaneously the two most basic properties necessary for clocked QCA operation, i.e., bistable switching behavior and clocked control.


Bennett clocking of quantum-dot cellular automata and the limits to binary logic scaling.
A promising alternative to clocking requires only altering the timing of the clocking signals so that bit information is simply held in place by the clock until a computational block is complete, then erased in the reverse order of computation, which results in ultralow power dissipation without additional circuit complexity.

It is shown that that control of molecular QCA can enable feedback loops, memories, planar circuit crossings, and versatile circuit grids that support feedback and memory, as well as data flow in any of the ordinal grid directions.
Clocking of molecular quantum-dot cellular automata
A simplified model of this clocking method is presented and its behavior as a molecular shift register is examined and it is shown that the clocking signals in this scheme originate from wires buried below the QCA surface.
Consequences of Many-Cell Correlations in Clocked Quantum-Dot Cellular Automata
Quantum-dot cellular automata (QCA) provides a basis for classical computation without transistors. Many simulations of QCA rely upon the so-called intercellular Hartree approximation (ICHA), which
Power gain and dissipation in quantum-dot cellular automata
Quantum-dot cellular automata (QCA) may provide a novel way to bypass the transistor paradigm to form molecular-scale computing elements. In the QCA paradigm information is represented by the charge
Role of correlation in the operation of quantum-dot cellular automata
The intercellular Hartree approximation largely reduces the number of state variables and still gives good results especially when the system remains near ground state, suggesting that a large part of the correlation degrees of freedom are not essential from the point of view of the dynamics.
Exponentially Adiabatic Switching in Quantum-Dot Cellular Automata
We calculate the excess energy transferred into two-dot and three-dot quantum dot cellular automata systems during switching events. This is the energy that must eventually be dissipated as heat. The

This paper aims to find an intermediate solution that exists somewhere in the solution space spanned by the ICHA and the full Hamiltonian, and promises to yield significant results within the QCA research community.
