Entangled Qubits

Entanglement

Let's now discuss what that means for entangled qubits, which are essentially a pair (or more) of quantum bits (qubits) that are in a unique quantum state where their individual properties become correlated, making it so that their states are dependent on one another regardless of their physical proximity. One qubit could be located across the plane from another and still have entanglement, as it's merely a concept of relationship and not space. Entanglement is an intriguing and basic quantum mechanical phenomenon that defies common sense and is essential to many areas of quantum computing and quantum information processing.
The independent states of qubits cease to exist when they become entangled. They instead combine to generate a single, entangled state that is not simply the sum of the individual qubit states. Unique characteristics and behaviors that are not feasible with classical systems can be seen in this entangled state. For instance, in bytes, information is simply stored as binary, however with qubit entanglement, we can utilize the specific values between 0 and 1 as well as qubit node weights.
Now let's consider a pair of entangled qubits, often referred to as a Bell pair by experts. The general entangled state of this pair can be represented most basically as:
|Ψ⟩ = α|00⟩ + β|11⟩,
where |00⟩ and |11⟩ are the computational basis states, and α and β are complex probability amplitudes that determine the correlations between the qubits. To clarify, computational basis states are essentially the two states of a qubit, being  -
∣ 0 ⟩ \vert 0 \rangle ∣0⟩ 
and 
∣ 1 ⟩ \vert 1 \rangle ∣1⟩
To keep it simple, they are the z-basis, which would include atoms, nuclear spins, or a polarized photon.
