Exploring Quantum Fault Tolerance and Quantum - dot Cellular Automata

1. Quantum Fault Tolerance

1.1 The Need for Quantum Fault - Tolerant Circuits

Quantum computing holds great promise for solving complex problems that are intractable for classical computers. However, quantum systems are extremely sensitive to noise and errors. Quantum fault - tolerant circuits are essential to ensure the reliability of quantum computations. Without fault - tolerance, even small errors can quickly accumulate and lead to incorrect results.
