What's Happening?
Quétélét & Associés Engineering (Q&A) has made significant strides in quantum optimization by implementing a linear-ramp Quantum Approximate Optimization Algorithm (QAOA) protocol. This approach has demonstrated a scaling advantage in solving combinatorial optimization problems, with error rates decreasing as the number of layers increases, remaining below 6% in most cases. The firm has updated its model for the probability of success, now describing it as a function of the number of qubits and a scaling factor that decreases with the number of layers. The research involved testing various combinatorial optimization problems, including NP-hard and APX-hard problems, using real quantum hardware and classical solvers for comparison.
