Technology

Quantum

New quantum technologies from sensors and clocks to quantum key distribution and computing will transform critical systems, solve complex real world problems, and challenge today’s encryption.

Quantum: The next competitive advantage 

Quantum computing is not about replacing today’s systems, it’s about amplifying business performance where classical computing falls short. Utilising quantum mechanics through quantum algorithms, hybrid quantum-classical systems open new possibilities for optimisation, advanced simulation, and data driven decision making.  

We work with forward-thinking organisations to turn emerging quantum technologies into clear commercial opportunities, preparing leaders to act decisively as quantum computing moves from research to real world impact.

What is quantum computing?


Quantum computers use quantum effects that are only relevant at very small scales. Their basic unit, the qubit, can exist in a superposition of multiple states at once unlike a classical bit, which is only 0 or 1. Because many qubits can process superposed states in parallel, quantum computers can outperform classical machines on certain complex problems.

Introductory papers

Our paper, “A Minimal Introduction to Quantum Computing” has been written to help ease understanding of quantum computing by computing professionals such as programmers, machine learning engineers and data scientists.

Drawing directly from the experience of the first author, who began this journey as an AI/ML professional, with the help of the second author, a quantum computing professional, this approach abstracts away from the physics underlying quantum computing and frames it in the model of computation similar to Turing machines.
