We design the algorithms that make quantum computers useful.
The Center of Excellence in Quantum Technology works on quantum computing and simulation. What we build is software — mostly algorithm design: the mathematics that decides whether a problem can be solved at all, and the code that decides whether it can be solved today.
The hard case is a trap like this one: a local minimum almost as good as the answer, with a wall in between. A classical search has to climb the wall. A quantum one goes through it, at constant energy — faintest in the middle, where the amplitude inside the barrier is smallest.
Four research pillars
CEQT is not organised around laboratories, because algorithms and simulations do not have room numbers. It is organised around four bodies of method.
Pillar 1
Algorithm design
Turning hard problems into forms a quantum machine can attack.

Simulation
Modelling systems that are too entangled, too many-bodied or too adaptive to solve directly.
Explore →Pillar 3
Software & platforms
The layer between an algorithm on paper and an algorithm that runs.
Explore →Pillar 4
Foundations
The mathematics that decides what is computable at all.

Every cell is a claim we can substantiate. The level is the honest part: lead means published results we will show you, emerging means early work and no promises.

Adiabatic Quantum Computation for Cyber Attack and Defense Strategies
Sanpawat Kantabutra
Cyber security has become increasingly important in today’s world widely connected by the Internet. Many important problems in the cyber security domain can be framed as optimization problems. Recently there has been much progress in applying quantum annealing to solve optimization problems in various application domains. In this article quantum annealing is shown to solve hard problems in cyber security from the perspectives of both attack and defense. In the process a few new techniques for QUBO construction are also illustrated and can potentially be used to solve problems in other application domains.

Why this one
It is the shape of most of our work: take a problem an engineer already recognises, find the formulation that a quantum machine can actually attack — here, QUBO — and be explicit about what the classical alternative already achieves.
The follow-on result, a hybrid classical–quantum treatment of a layered cybersecurity model, appeared in The Journal of Supercomputing in 2025.
