Trapped-ion quantum processors have the advantage of “all-to-all connectivity” and have gate operations and coherence times of the highest order. In the ATIQ project, reliable trapped-ion quantum computing demonstrators will be developed for complementary use cases, including quantum chemistry, optimization problems with fully parallelizable gates, and credit risk assignment, with the goal of demonstrating a quantum advantage that has practical utility. Goals and approach: Along the way, 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 tailor algorithms and compilers to the characteristics of the quantum computing hardware and to optimize the hardware architecture for specific algorithms. Innovation and prospects: Within 30 months, a first generation demonstrator with 24/7 user access for 10 qubits and >99% Q-factor in all-to-all gate operation, including hybrid computational capabilities through a connection to an HPC, will be made available. By the end of the project, system performance will be increased to 40+ qubits, with single- and multi-qubit gate grades of 99.9%+ and 99.5%+, respectively.
