Crosstalk in Quantum Cellular Automata Networks
Sachindeb Jana, Kisalaya Chakrabarti, Angsuman Sarkar · 2025
Quantum Cellular Automata (QCA) is a promising computational paradigm leveraging quantum mechanics for high-speed data processing with minimal power consumption. QCA circuits use quantum cells to encode and transmit data via Coulombic interactions between adjacent cells. Crosstalk in QCA networks refers to unintended interference between quantum states of neighboring cells, potentially degrading processing speed and accuracy in computations and data transfer. This study examines the nature, causes, and performance impacts of crosstalk, along with various mitigation strategies. Observations reveal varying power consumption due to errors in identical logic circuits, enabling optimal circuit selection. Future research directions focus on minimizing crosstalk and improving QCA reliability for low-power devices and quantum computing applications.
