Dirac notation is a compact and elegant mathematical formalism used in quantum mechanics. It represents quantum states and their relationships efficiently:
Ket (|ψ⟩): Denotes a quantum state, typically a vector in a Hilbert space.
Bra (⟨ϕ|): The dual (conjugate transpose) of a ket, representing a row vector.
Inner Product (⟨ϕ|ψ⟩): A scalar value obtained by combining a bra and a ket, representing the overlap or probability amplitude between two states.
This notation simplifies calculations involving operators, eigenstates, and measurements in quantum mechanics. In this video, I discuss the above in an intuitive manner.
