# Time-bin encoding qudits

Time-bin encoding is a technique used in Quantum information science to encode a qubit of information on a photon. Wikipedia

Is there a generalization for $$n$$-th level qudits?

• This question seems to broad. Are there specific parts of the Wikipedia entry which you don't understand/you have questions about? Also, why do you link to an article which does not use time-bin encoding to encode a 10-level system? – Norbert Schuch Dec 9 '18 at 13:28
• @NorbertSchuch I have narrowed the question. Also, the linked article was meant as an example of a (frequency-bin?) photonic qudit. – meowzz Dec 9 '18 at 16:05
• this is a bit confusing. "Time-bin encoding" means to use the time as degree of freedom on which to store the (quantum) information. As such, this sort of encoding can in principle encode arbitrary high-dimensional qudits. The limitation is obviously in the actual experimental constraints. – glS Dec 9 '18 at 19:16
• @glS Do you have any references regarding encoding arbitrary high-dimensional qudits? – meowzz Dec 9 '18 at 19:28
