In order to link and encode information in critical industries such as banking,
The peculiarity is that quantum processes are truly random: this is guaranteed by the laws of physics. Thus, information about an event appears literally at the moment the event occurs, not earlier.
Using the idea of true randomness laid down inAt the heart of quantum physics, Australian scientists from the Macquarie University Photonics Research Center have developed a diamond laser system in which each generated pulse of laser light has its own direction of polarization, determined by the quantum motion of carbon atoms in the diamond lattice.
The new development is faster than previous analogues, since the randomness is generated by the laser itself. This makes the device simpler and safer.
This is a completely new tool for creatingquantum randomness. We hope that this type of device will provide end users in areas such as encryption and quantum simulation with a new opportunity to simplify and improve technology.

The authors note that they can also change the degree of randomness in the laser. In the future, this will allow studying the transition from quantum randomness to classical determinism.
