Combinatorial optimization problems refer to finding the optimal or near-optimal solution(s) within certain constraints or conditions. They are used in various fields, such as optimizing delivery routes in logistics and creating schedules. The characteristic feature of Ising machines is that they ap...

Matrix functions, for example, computing the exponential, inverse, square root or logarithm of a matrix, are ubiquitous across computational science and engineering. They transform the eigenvalues of the input matrix by the target function. We present a general method for directly synthesising block...

We address the challenge of high-dimensional black-box optimization (BBO), where the objective function is unknown, non-differentiable, and expensive to evaluate. This problem arises in various real-world engineering tasks such as turbomachinery design using computational fluid dynamics (CFD) and au...

The two-dimensional cutting stock problem deals with the task of cutting out required rectangular pieces of certain fixed sizes and quantities out of some base material. In principal one can optimize the process in many different ways. The simplest objective is to minimize the waste area, but one ca...

Distributed control systems in industrial cyber-physical environments, such as water treatment processes, rely on tightly coupled interactions among sensors, actuators, and controllers. As demonstrated in a three-tank system model, even minor faults or cyber-attacks at critical nodes can propagate r...

Black-box optimization (BBO) is crucial in engineering domains (e.g., aerodynamic shape design), where the objective function is evaluated through computationally expensive simulations or physical experiments. Because these evaluations are time-consuming, the total number of evaluations becomes a cr...

Dissipation and irreversibility are central to most physical processes, yet they lead to non-unitary dynamics that are challenging to realise on quantum processors. Splitting methods (i.e. Trotterization) are popular for simulating unitary dynamics because the simulation problem becomes one of findi...
