The difference between quantum and traditional computing lies in so called speed and reversibility. Quantum computing is inherently reversible. This course aims to introduce quantum computing and reversible computation. Conventional computing, regardless of its realization technique, has internal power dissipation. Theoretically, using reversible computation the internal power dissipation becomes zero because reversible computation does not lose information. We will discuss the differences between conventional computing and reversible/quantum computing. Then quantum ternary circuits will be explained. We will also consider quantum circuits and algorithms. We will demonstrate how quantum computing will increase our computing power towards infinity.
