In the realm of quantum information, the scalar (inner) product of any quantum state by itself is a fundamental concept that holds significance in the understanding of quantum systems. This scalar product, denoted as ⟨ψ|ψ⟩, where ψ represents the quantum state, provides essential information about the state itself. It serves as a measure of the

What is the geometric interpretation of qubit states?

The geometric interpretation of qubit states is a fundamental concept in the field of quantum information. In quantum mechanics, a qubit is the basic unit of quantum information, analogous to a classical bit. However, unlike classical bits, which can only exist in one of two states (0 or 1), qubits can exist in a superposition
