Heathrow closure: what caused the fire and why did it bring down the whole airport?

The closure of Heathrow Airport has caused chaos, leaving thousands of passengers stranded. More than 1,300 flights have been affected, about 120 of these were already in the air.

A panel of experts offer their insights – and consider the implications of such a major incident.

Is your software stack #quantum ready? The #julialang #sciml differential equation solvers are able to to not only target CPUs, GPUs, and IPUs with good performance, but quantum computers as well through the QuDiffEq.jl backend without changing your code. Check out this work where a group of researchers tested its accuracy for modeling power systems dynamics, showing its correctness and readiness for real-world DAEs!

arXiv.orgSolving Differential-Algebraic Equations in Power Systems Dynamics with Quantum ComputingPower system dynamics are generally modeled by high dimensional nonlinear differential-algebraic equations due to a large number of generators, loads, and transmission lines. Thus, its computational complexity grows exponentially with the system size. In this paper, we aim to evaluate the alternative computing approach, particularly the use of quantum computing algorithms to solve the power system dynamics. Leveraging a symbolic programming framework, we convert the power system dynamics' DAEs into an equivalent set of ordinary differential equations (ODEs). Their data can be encoded into quantum computers via amplitude encoding. The system's nonlinearity is captured by Taylor polynomial expansion and the quantum state tensor whereas state variables can be updated by a quantum linear equation solver. Our results show that quantum computing can solve the dynamics of the power system with high accuracy whereas its complexity is polynomial in the logarithm of the system dimension.
