Why is the Hadamard gate self-reversible?
The Hadamard gate is a fundamental quantum gate that plays a crucial role in quantum information processing, particularly in the manipulation of single qubits. One key aspect often discussed is whether the Hadamard gate is self-reversible. To address this question, it is essential to delve into the properties and characteristics of the Hadamard gate, as
What is the Bloch sphere representation of a qubit?
In quantum information theory, a Bloch sphere representation serves as a valuable tool for visualizing and understanding the state of a qubit. A qubit, the fundamental unit of quantum information, can exist in a superposition of states, unlike classical bits that can only be in one of two states, 0 or 1. The Bloch sphere
The scalar (inner) product of any quantum state by itself is equal to one for both pure and mixed states?
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 relationship between the Quantum Fourier Transform and the Hadamard Transform?
The Quantum Fourier Transform (QFT) and the Hadamard Transform are two important operations in the field of quantum information processing. While they share some similarities, they serve distinct purposes and have different mathematical representations. In this explanation, we will delve into the relationship between these two transforms, highlighting their similarities and differences. The Quantum Fourier
