qgrad_qutip.coherent

qgrad_qutip.coherent(N, alpha)

Generates coherent state with eigenvalue alpha by displacing the vacuum state by a displacement parameter alpha.

Parameters

• N (int) – Dimension of Hilbert space

• alpha (float/complex) – Eigenvalue of the coherent state

Returns

Coherent state (eigenstate of the lowering operator)

Return type
