displaced_squeezed_state(a, phi_a, r, phi_r, hbar=2.0)[source]¶

Returns a squeezed coherent state

Parameters

• a (real) – the displacement magnitude

• phi_a (real) – the displacement phase

• r (float) – the squeezing magnitude

• phi_r (float) – the squeezing phase $\phi_r$

• hbar (float) – (default 2) the value of $\hbar$ in the commutation relation $[\x,\p]=i\hbar$

Returns

the squeezed coherent state
