Quantum technology is one of the fastest-growing areas of engineering and physics on our planet. The technology aims to exploit the principles involved in quantum physics to deliver next-generation support in fields such as communications, gaming and computing.
It’s only half-a-century since quantum physics helped foster a new era of nuclear power and now quantum mechanics is being used to redefine so many other elements of the technological world today. One area of interest in this article surrounds the emergence of quantum random number generators.
Quantum random number generators are at the heart of the quantum revolution. They are designed to improve the integrity and security of all manner of platforms and networks, abiding by quantum mechanics. Traditionally, digital random number generators have utilised algorithms and seed numbers to generate random number sequences. However, there has been an increasing need for randomised number generators that are ‘truly’ random.
What do we mean by truly random?
For a random number generator to be ‘true’, as opposed to what’s known as ‘pseudorandom’, it must rely on an external physical variable to act as a source for its number seed. External sources could include static airwaves or even radioactive decay. Put simply, anything that cannot be remotely manipulated or engineered.
Quantum random number generators are already revolutionising the world of cybersecurity, with ongoing risks of exploitation from cyber-criminals. The encryption of networks and systems leans heavily on the generation of random number sequences for logins and such like. If these sequences can somehow be guessed, there are major flaws in these systems as sensitive files and data can be seriously compromised. This is particularly important to maintain the integrity of connected devices to the so-called Internet of Things (IoT).
They could also make a huge difference in the iGaming industry, where trust and integrity is a must in such a tightly regulated sector. One of the main use cases of random number generators in iGaming is for the randomisation of slot game outcomes, as well as the random triggering of progressive jackpots.
These jackpots are continuously increasing, with a small percentage of a player’s stake added to the jackpot with every spin they make. Until suddenly, when the progressive jackpot is triggered during a random spin. With such intrigue and expectation surrounding progressive jackpot slots, it’s no surprise to see they’re a focal point of most leading online casinos. There are well over 100 listed at most entertainment platforms, across all manner of themes, which can yield five, six, seven and even eight-figure payouts on occasion. The algorithms which trigger progressive jackpots are independently verified for fairness, but it won’t be long until quantum RNGs are used to cement the integrity of the iGaming sector.
Other possible uses of quantum RNGs and the challenges of integration
There are so many other potential applications for quantum RNGs. They could help to improve the authenticity and efficiency of sampling for experiments and surveys, eliminating any aspect of bias and thereby enhancing the validity of results. Looking at financial investors and traders, quantum RNGs could be used to improve the modelling of assets to accurately forecast moves in the stock markets.
The route to quantum RNGs going mainstream won’t be without its hurdles to overcome. One of the biggest obstacles in the way is combining quantum technology with legacy systems. The application of quantum RNGs usually need very specific conditions or criteria to operate in, which could be at odds with a company’s existing infrastructure. For the time being, this could make quantum RNGs harder to pair with everyday devices which can’t function in the ultra-low temperatures needed for quantum RNGs to operate.
Steps are being taken in the right direction, though. A team of University of Bristol researchers have made a breakthrough with the development of a chip-based quantum RNG capable of working at room temperatures. This would certainly open the door for quantum RNGs to be paired with mainstream technologies.
In summary, quantum RNGs are set to lead the charge for the quantum revolution. It’s a case of when rather than if these RNGs can help to bring a sense of clarity and reassurance over the ‘true’ nature of digital security.
