EuropeanCallDelta#

class EuropeanCallDelta(num_state_qubits, strike_price, bounds, uncertainty_model)[source]#

Bases: EstimationApplication

Estimation application for the European Call Option Delta. Evaluates the variance for a European call option given an uncertainty model. The payoff function is f(S, K) = max(0, S - K) for a spot price S and strike price K.

Parameters:

  • num_state_qubits (int) – The number of qubits used to encode the random variable.

  • strike_price (float) – strike price of the European option

  • bounds (Tuple[float, float]) – The tuple of the bounds, (min, max), of the discretized random variable.

  • uncertainty_model (QuantumCircuit) – A circuit for encoding a problem distribution
