There is a recent BBC article on a new attack against a key component of Quantum Cryptography: Key Transportation.
There are 3 main components to a cryptographic system:
– The strength of the algorithms used (close/open, random generator, collision, etc)
– The integrity of the system (implementation, key storage, devices security, etc)
– The transportation of keys (no full or partial interception of the keys, etc)
Quantum Cryptography has for some been seen as the future for ensuring the integrity and detection of any interception attempts during key transportation.
I am not a Quantum Physic expert, but what I understand is that key transportation is done through light, where photons of light are sent to the receiver who will inspect the states of those photons to reconstruct the key. It is similar of sending a stream of bits which make the key, apart from the fact that in Quantum Physics a photon has not just a binary state ...

In the never ending story that is more issues/concerns with Dropbox, there is an interesting article discussing the recent changes of Terms and Conditions with using Dropbox:
TechRepublic Post
In a nutshell, Dropbox is trying to protect themselves with what they do and can do with your data hosted in their data centre. So it means granting Dropbox and those they work with“worldwide, non-exclusive, royalty-free, sub-licensable rights to use, copy, distribute, prepare derivative works “ from your data.
The TechRepublic article stresses that it is already the case with sites such as Facebook. There is however a big difference. Facebook is mainly used for social content, personal “stuff” (to use Dropbox’s term). Dropbox is not only used for personal “stuff” but also for professional “stuff”.
