Criteria for quantum computation existence
In this section, we will be looking at the conditions which are necessary for making quantum computing a reality. All the current quantum computers are affected by quantum noise, which is also known as decoherence. Decoherence creates loss of quantum information and is therefore considered as a type of noise, and happens when the qubits interact with the environment over a long duration of time. A high accuracy of the computations performed by quantum computers is achieved when there is less interaction of qubits with the environment. Decoherence destroys the unitary operations that are a very important aspect of quantum computation, as we discussed in Chapter 1, Essential Mathematics and Algorithmic Thinking.
There are primarily four conditions that are required to make quantum computing happen. They are as follows:
- Quantum information depiction
- Unitary transformation capability
- Making the reference initial quantum states...
