True, but in OA people can be subverted, so keep your hardware close.

This is why one-time pads are created ahead of time and shared in a face-to-face meeting. Given the need to generate the numbers offline, speed is of secondary importance.
I think that's talking about keys, not pads. Random numbers can be used for both.
Keys can be securely transmitted using quantum key distribution.
If you have a quantum secure channel, you could also transmit arbitrarily large one-time pads that could then later be used for, e.g., cellphone communication.
