Expectation Value (Quantum State)

Available identifiers

MaRDI QIDQ6673967

expected (mean) value of a quantum-mechanical observable, calculated from a state vector

Defining Formula: $⟨\hat{O}⟩\equiv ⟨\psi |\hat{O}|\psi ⟩$

$\hat{O}$ symbol represents Quantum Mechanical Operator

$⟨\hat{O}⟩$ symbol represents Expectation Value (Quantum State)

$\psi$ symbol represents Quantum State Vector
