Implementation of quantum algorithms from finance and chemistry on a quantum demonstrator (ATIQ)

In the ATIQ project, reliable quantum computing demonstrators based on trapped ions are being developed for complementary use cases, including quantum chemistry, optimisation problems with fully parallelisable gates and credit risk allocation, with the aim of demonstrating a quantum advantage that has practical utility.

Within 30 months, ATIQ aims to develop an initial generation of reliable, user-friendly and 24/7 available quantum computing demonstrators based on ion trap technology. For this purpose, the leading groups in ion trap research at universities in Hannover/Braunschweig, Siegen and Mainz have joined research facilities and industry partners.

There are three key technological challenges that ATIQ will address:

  • Alignment-free optical preparation, manipulation and readout,
  • reliable cryogenic electronics integrated into the trap and reliable trap technology, and
  • Real-time control and automation for 24/7 operation and user access.

Where appropriate, these challenges will be addressed as part of a hardware-software co-design strategy to customise the algorithms and compilers to the properties of the quantum computing hardware and to optimise the hardware architecture for specific algorithms.

The collaborative project “ATIQ – Quantencomputer mit gespeicherten Ionen für Anwendungen” is part of the BMBF funding initiative “Quantencomputer-Demonstrationsaufbauten” (quantum computing demonstrator set ups). The project is scheduled to run between 1 December 2021 and 30 November 2026 with overall funding amounting to 44.5 million euros (37.4 million euros of BMBF funding plus funding provided by the involved businesses). ATIQ is coordinated by Leibniz University Hannover and brings together the expertise of 25 partners. Additional partners include Johannes Gutenberg University Mainz, Siegen University, TU Braunschweig, RWTH Aachen University, Physikalisch-Technische Bundesanstalt (PTB), Fraunhofer-Gesellschaft, as well as the businesses AMO GmbH, AKKA Industry Consulting GmbH, Black Semiconductor GmbH, eleQtron GmbH, FiberBridge Photonics GmbH, Infineon Technologies AG, JoS QUANTUM GmbH, LPKF Laser & Electronics AG, Parity Quantum Computing Germany GmbH, QUARTIQ GmbH, Qubig GmbH and TOPTICA Photonics AG. Associate partners include AQT Germany GmbH, Boehringer Ingelheim, Covestro AG, DLR-SI, Volkswagen AG and QUDORA Technologies GmbH.
