Barcelona-based analog quantum computing startup Qilimanjaro Quantum Tech has released version 0.3.0 of its open-source QiliSDK framework and QiliSim C++ backend engine. Built to unify circuit-based digital algorithms, Hamiltonian-driven analog time evolution, and hybrid variational workflows within a single Python API, the software update introduces GPU acceleration for variational annealing and expands classical optimization capabilities.
The v0.3.0 release adds full support for Python 3.14, an upgraded tensor network engine (QTensor), and a dedicated classical solvers module featuring a high-performance simulated annealing algorithm. For analog schedule modeling, the framework now supports time-dependent noise profiles, simplified operator drawing tools, and a unified Expression class that merges symbolic terms and variables. Within the underlying C++ simulator (QiliSim), the team integrated a new stabilizer state simulator for efficient Clifford circuit verification and enabled GPU acceleration to speed up complex variational schedules.
