The chip could deliver the world's most secure encryption keys in a package small enough to use in a smartphone, tablet or laptop, researchers have said, by using quantum mechanics.
Random number generators are crucial to the encryption that protects our privacy and security when buying products online or withdrawing cash from an ATM.
Now, for the first time, engineers have developed a tiny, fast random number generator based on quantum mechanics.
The number generator uses the inherently random quantum properties of light to generate numbers, rather than an algorithm mimicking a dice that could more easily be hacked.
The device is the smallest and fastest of its kind, the researchers, from the Institute of Photonic Sciences in Barcelona have said.
The study, published in the journal Optica, is a big step on the path to incorporating quantum-based random number generators into computers and other devices.

The researchers used ‘photonic integrated circuit’ (PIC) technology – a way of integrating components such as lasers and detectors - to create two quantum number generators that together measure 12 square millimetres.
The new device could in theory be integrated with traditional electronics and operates at speeds in the range of gigabits per second.
This is fast to encrypt communication data such as phone or video calls in real-time, or to protect large amounts of data travelling to and from a server used by a social media service, for example.
The random number generators used today are based on computer algorithms or the randomness of physical processes, meaning they are essentially complex versions of rolling dice over and over again to get random numbers.
But while the numbers generated appear to be random, knowing certain information, such as how many ‘dice’ are being used, can allow hackers to work out the numbers, leaving secured data vulnerable.
To overcome this problem, the new chip generates random numbers based on the quantum properties of light - a process that is inherently random and therefore impossible to predict no matter how much information is known.
Although other researchers have developed quantum random number generators before, they have all been either larger or slower than the chip.
Research leader Valerio Pruneri explained: ‘We have previously shown that the quantum processes taking place exhibit true randomness.
‘In this new paper, we made a huge technological advance by using a new design that includes two lasers that interfere with each other in a confined space.
‘This makes the device smaller while keeping the same properties that were used in the past experiments.’
