Locally synchronous, globally asynchronous design for quantum-dot cellular automata (LSGA QCA) [PDF]
5th IEEE Conference on Nanotechnology, 2005., 2005 The concept of clocking for QCA, referred to as the four-phase clocking, is widely used. However, inherited characteristics of QCA, such as the way to hold state, the way to synchronize data flows, and the way to power QCA cells, make the design of QCA circuits quite different from VLSI and introduce a variety of new design challenges and the most ...

Ab initio studies of counterion effects in molecular quantum‐dot cellular automata
Journal of Computational Chemistry, Volume 45, Issue 7, Page 392-404, March 15, 2024.Randomly‐placed external counterions near ionic computational molecules may degrade QCA device operation. Ab initio calculations show that presence of nearby counterions affect the electron transfer (ET) matrix element and the inner‐sphere reorganization energy of a molecule.
