• Abstract: The Binet-Fibonacci calculus, as $\varphi \varphi'$ - two base quantum calculus, relates Fibonacci derivative with Binet formula of Fibonacci number operator, acting in Fock space of quantum states. It provides a tool to study the Golden oscillator with energy spectrum in form of Fibonacci numbers. Here we generalize this model to supersymmetric number operator and corresponding Binet formula for supersymmetric Fibonacci operator ${\cal F}_{\cal N}$. It determines the Hamiltonian of supersymmetric Golden oscillator, acting in $H_f \otimes H_b$ - fermion-boson Hilbert space and belonging to $N=2$ supersymmetric algebra. Trace on fermions of this model reduces the Hamiltonian to the Golden oscillator. The eigenstates of the super Fibonacci number operator are double degenerate and can be characterized by a point on the super-Bloch sphere. By the supersymmetric Fibonacci annihilation operator, we construct the supersymmetric coherent states as eigenstates of this operator. Entanglement of fermions with bosons in these states is calculated by the concurrence, represented by the Gram determinant and Fibonacci exponential functions. These functions have been appeared as descriptive for inner product of the Golden coherent states in Fock-Bargmann representation. We show that the reference state, coming from the limit $\alpha \rightarrow 0$ and corresponding von Neumann entropy, measuring fermion-boson entanglement, are characterized completely by the Golden ratio.
