While bits are nothing new to us, the term “qubit” may be unfamiliar to some. Similar to classical information, the fundamental building block of a quantum system is the quantum bit, or qubit. Qubit and its features are defined and discussed in this blog. To store data in quantum computers, we employ a basic building block called a qubit. In contrast to bits, which exist in binary states like 0 or 1, qubits exist in quantum states like |0⟩ and |1⟩ and they can exist in superposition of these two states as well. |ψ>=α|0⟩+β|1⟩, where α and β are complex numbers. which represents probability amplitudes of corresponding basis state. The state will initially at |ψ> and upon measuring the sys...
