Quantum key distribution is a method that utilizes the “non-clonable” property of a quantum state in order to generate a secure key for encryption systems. Traditionally, QKD schemes have relied on polarization states of light to encode information, which are inherently limited to two dimensions. By using a higher dimensional basis set, one can encode more information as well as be more secure against eavesdropping. Orbital angular momentum states of light present an infinite dimensional basis set. Recently, we constructed a QKD system using OAM states of light of up to 8 dimensions.
