What is the technology?
Quantum computing is the technology developed using the properties of quantum physics to support the mechanism involved with storing and computing data, in a computer. Unlike regular computers, it functions in qubits. This means it can process highly complex and unpredictable data simultaneously at an exponentially higher speed than a normal computer.
What does it do?
Qubits exists in the realm of possibilities, between probable outcomes, and operates on features of quantum physics like superposition and entanglement. This allows calculations to be made by superimposing probabilities to explore potential outcomes before definite measures are taken. For instance, quantum computers can simultaneously sift through thousand possible combinations with rapid speed before arriving at the best possible outcome. Similarly, entanglement allows for independent qubits to be moved around or paired and processed through superposition to reach the best possible outcome, allowing for extremely complex combinations to be resolved promptly and efficiently.
Why should I care about it?
Not only does quantum computing help tackle some of the most complex and uncertain issues but it does this at an expedited speed, making this technology exceedingly favourable in markets dealing with volatile data. Quantum computing has also given way to quantum key distribution, an un-hackable network allowing users to share highly sensitive and confidential information via the internet.
Scientist too are beginning to reap the benefits of quantum computing and are using it to stimulate chemical reactions in their quest to develop drugs to cure cancer, Alzheimer’s and other such ailments.
Who is talking about it?
Google’s investing heavily in developing this technology. Companies like Honeywell and IBM too are working towards developing this technology, with IBM planning to have a 1,000-quibit quantum computer in place by 2023.
BT and Toshiba have also recognised the growing importance of quantum computing and have developed UK’s first industrial deployment of a quantum-secure network.
