Quantum dots generated using this method can be used in quantum cryptography. What is the method employed? Correct Answer Molecular beam epitaxy

In (Ga)As quantum dots in GaAs can be grown using the molecular beam epitaxy method or metalorganic vapour phase epitaxy (MOVPE). These QDs can be used in quantum cryptography (i.e., single photon sources) and in quantum computation.
