Steps of a Quantum Algo
In general, a quantum algorithm is a sequence of five steps:
- Encode the input data into the state of a set of qubits.
- Bring the qubits into superposition over many states (i.e., use quantum superposition).
- Apply an algorithm (or oracle) simultaneously to all the states (i.e., use quantum entanglement amongst the qubits); at the end of this step, one of these states holds the correct answer.
- Amplify the probability of measuring the correct state (i.e., use quantum interference).
- Measure one or more qubits.
Specific Use Cases
Option Pricing
The problem of what option is worth can be solved, in simple instances, by closed form formula. However, in general, the exotics/complex product requires numerical simulation methods (such as Monte Carlo).
