This site contains various notes I have been making about Quantum Computing

Basic Concepts —
“Quantum computers are starting to approach the limit of classical simulation”
In quantum computing the basic variable that holds information is known as a qubit. Qubits un cannot be represented like classical bits as they obey the laws of quantum mechanics.
We can visualise a single qubit using the Bloch Sphere, which is a geometrical representation. By using the two variables pheta and phi we can represent each possible qubit state as a point on the surface of a bloch sphere.…

Quantum States —
Quantum memory Quantum memory is the Quantum version of traditional computer memory where instead of storing data as as 1 or 0, quantum memory will store a quantum state called a qubit.
A qubit is a unit of information stored as a vector, where the two directions are written as either a |1> or a |0>.
Bell state Bell states are four specific maximally entangled quantum states of two qubits.…
