JADE
JADE is one of the quantum simulators acquired through the EuroHPC pilot project HPCQS and located in Jülich, Germany.
HPCQS (High Performance Computer and Quantum Simulator Hybrid) aims to advance the integration of quantum systems with the European supercomputing infrastructure.
JADE is a neutral atom quantum computer, build out of Rydberg atoms suspended in ultrahigh vacuum and hold in place by arrays of tightly focused laser beams, so called optical tweezers. These optical tweezers manipulate the Rydberg atoms to perform quantum operations, offering a high scalability potential.
JADE will support cross-sectional applications, including drug design, supply chain management, intelligent charging of autonomous cars, FinTech and cybersecurity. In addition, the computing power of Pasqal’s Quantum Processing Unit (QPU) will be used for simulations in physics and chemistry as well as for quantum machine learning.

EuroQCS-Spain
EuroQCS Spain a is a EuroHPC quantum computer to be located in Barcelona, Spain.
EuroQCS Spain will be an analogue quantum computer in the form of a quantum annealer. Quantum annealing is effective in solving certain types of optimisation problems. The method is based on the concept of adiabatic evolution, where a system is slowly transformed from an initial state to a final state. The final state is designed in such a way that it represents the optimal solution of the optimisation problem, the so-called global optimum. Quantum annealing has been shown to be particularly effective for solving problems with a large number of local optima.
Quantum annealers can be used in various fields, including machine learning, finance and logistics.
EuroQCS Spain will complement the digital gate-based quantum computer that BSC already hosts and will be integrated into the EuroHPC world-class supercomputer MareNostrum 5.
