Surprisingly yes. One-time-pads are used in many "quantum encryption schemes." Typically these schemes are actually standard one-time-pad encryption with the key being distributed using Quantum Key Distribution(QKD). They are, theoretically unbreakable since there is no way to intercept the key thanks to quantum physics(in practice, there are some problems).

In theory, this is useful for highly sensitive messages that need to remain secure for ever no matter what breaks in known cryptographic primitives happen or what advances in computational power (particularly quantum computing) occur. 

There are commercial QKD schemes, though I do not know how much they are actually used.

Is OTP useful in modern electronic communication?
I want to change the column order visible when viewing or editing a list item. I have accessed the "Column ordering" interface via the list settings page on other lists in the past, but it isn't visible in this list's settings.



Cheers!
