The Jülich UNified Infrastructure for Quantum computing provides science and industry access to state-of-the-art quantum computing devices.
JUNIQ is a manufacturer-independent, comprehensive, public quantum computing user facility. JUNIQ, through its uniform a uniform quantum computing Platform as a Service (QC-PaaS), offers European users support and access to quantum computer emulators and quantum computing technologies of different types and levels of technological maturity. JUNIQ integrates quantum computers in the form of quantum-classical hybrid computing systems into the modular HPC environment of the Jülich Supercomputing Centre. A comprehensive overview is available in the NIC Symposium 2022 Proceedings.
The following Emulators and Quantum Computers are currently accessible via the JUNIQ-Cloud platform.
Quantum computer emulators simulate the operation of quantum computing devices on conventional computers.
The Jülich Universal Quantum Computer Simulator JUQCS is a massively parallel emulator of gate-based quantum computers for conventional computers of any type and size with CPUs and GPUs. JUQCS has set the world record of simulating a universal quantum computer with 48 qubits. On JUWELS, one of the HPC systems at the Jülich Supercomputing Centre, JUQCS can simulate quantum circuits of up to 43 qubits.
The 30-qubit Atos Quantum Learning Machine simulates gate-based quantum computers with up to 31 qubits. Learn more on Atos’ Website.
D-Wave Advantage™ System JUPSI
The D-Wave Advantage System is an annealing quantum computer with more than 5000 superconducting qubits. With quantum annealing, computations are carried out by first bringing a connected system of qubits into a simple and known lowest energy state described in the basis of an initial Hamiltonian. This state turns out to be a uniform superposition state described in the basis of the final Hamiltonian that encodes the problem to solve. The system is then shifted to the lowest energy state of the sought classical problem, the second Hamiltonian, by adiabatically changing the interactions of the qubits. Quantum annealing can especially be used to solve optimization, sampling and machine learning problems. Learn more on D-Wave’s website.
At the end of 2023, a Pasqal quantum simulator with 100 + neutral atom qubits will be installed. The Pasqal quantum simulator is funded by the EuroHPC project HPCQS. Learn more on the Pasqal’s website.
OpenSuperQ Quantum Computer
In the Quantum Flagship project OpenSuperQ, a gate-based quantum computer with superconducting qubits, has been developed and made accessible via JUNIQ.
Plans for a new quantum computer building started in early 2019 (see animated JUNIQ building).The construction of the JUNIQ building officially began on 30 July 2020 with the groundbreaking ceremony by Kristel Michielsen, Thomas Lippert, Wolfgang Marquardt, Birgit Spengler, and Harald Lange (see news flash). The progress of construction could be followed via a webcam, the images of which were edited into a time-lapse video. In summer 2021, the construction of the building was completed. Since fall 2021, it hosts a D-Wave Advantage system. A Pasqal Quantum Simulator is expected to be installed in the near future. Take a virtual tour through the building and learn more about its architecture, its special infrastructure, and the hosted and planned quantum computing devices.
