A team of international scientists has developed a laser that can generate 254 trillion random numbers per second, a hundred times faster than a computer-based random number generator (RNG).
Although random number generation has been around for thousands of years, it is increasingly important in computing because it forms the basis of Encryption.
And with more devices online than ever before, the need for faster encryption that can block bad items is becoming more and more important.
Computer simulations of complex systems, such as the Earth’s climate or the stock market, also require many random numbers to correctly capture real-life events.
Referring to the prevailing need for computer-based random number generators in modern technology, Google demonstrated the apparent superiority of a quantum computer of 53 qubits using the computer-based random number generator problem.
It is for this reason that the new system can be a game-changer, as it can generate 250 terabytes of random bits per second.
And it was so fast that the team behind it struggled to record its output – over 254 trillion random numbers per second – with the high-speed camera.
According to the researchers, the system outperforms physical random number generators in speed and through its ability to generate many bit streams simultaneously.
And it was published Results In Science, the new invention uses a small laser, just one millimeter long, that reflects light between mirrors placed at both ends of an hourglass cavity before exiting the device.
And unlike previous laser-based systems, the new process can amplify many light modes simultaneously.
These interfere with one another to generate rapid fluctuations in intensity that the team recorded with the camera, which measured the intensity of light at 254 points across the beam during about every trillionth of a second.
But the speed at which the laser was pumping data means that the camera can track it for only a few seconds before its memory becomes full, after which the data is uploaded to a computer.
The random generator system was jointly developed by researchers from Nanyang Technological University in Singapore, Yale University and Trinity College Dublin. And it was made in Nanyang Technological University.
For the future of the system, the team aims to make it ready for practical use by integrating the laser into an integrated chip, and this enables the random numbers it generates to be directly entered into the computer.
