Alternative Forms of Quantum Computing
Eduardo R. Mucciolo · 2025
The approach we considered so far for computing using quantum mechanics relies on preparing a suitable initial state, applying single and two-qubit quantum gates, and performing measurements. It is known as the circuit model of quantum computing. Howeveer, this is not the only approach. In this chapter, we will cover a few alternatives. Some still rely on circuits to some extend, but they either explore alternative paradigms of fault tolerance, utilize protocols that do not require entangling gates, or avoid multi-shot computations. One of these alternative approaches is entirely based on measurements. Another requires fine tunning gates and repeating measurments.
