Quantum computing explained

Quantum computers are a new generation of problem solving machines which operate according to completely new rules. This new kind of computing will make entirely new forms of information processing possible, which will help to generate breakthrough discoveries in a variety of industries. It has the potential to revolutionise sectors such as financial services, pharmaceuticals, operations and logistics, and security amongst others through faster and more nuanced information processing.

Qubits, quantum gates and quantum software

Just like the ‘bit’ found in classical compute, quantum compute use qubits; short for “quantum bit”. It is the foundational unit of information in quantum computing. Their ability to be in a superposition means that quantum algorithms can use a group of qubits in a superposition to shortcut through calculations, giving them their innate capacity to work faster.

Quantum gates manipulate the quantum states of qubits, performing specific operations to allow for the execution of quantum algorithms and computations. Quantum algorithms can be hard to develop and programme, and the most promising applications hard to identify, however extensive research and experimenting of quantum algorithms is already underway by organisations and academics around the globe.
