Project description
Two dimensions, one quantum leap
Scaling up quantum processors while maintaining control and connectivity between qubits remains a major technical hurdle. In most trapped-ion systems, qubits are arranged in one-dimensional strings, limiting their interactions and complicating operations. With this in mind, the ERC-funded 2dQC project will switch to two-dimensional ion crystals. This compact layout allows quantum gates between any of the 100 ions, dramatically improving efficiency. Working with Alpine Quantum Technologies, the project aims to integrate these 2D crystals into commercial systems, achieving entangling gates with over 99 % fidelity. With standardised quantum software support, this approach could accelerate advances not just in quantum computing, but also in quantum simulation, precision measurement, and future quantum networks.
Objective
The development of a general-purpose quantum processor requires the possibility of scaling the device up to large numbers of quantum bits and the realisation of fault-tolerant quantum gate operations between them, ideally with the possibility to carry out gates between arbitrary qubit pairs. In trapped-ion based implementations, quantum gates are typically carried out on sub-ensembles of qubits that are stored in linear strings of ions. These sub-ensembles are subsequently connected by shuttling ions around or using photonic interfaces. To reduce the footprint of such a device, we propose to replace linear strings by two-dimensional ion crystals and directly operate on 100 ion-qubits. Within this application, we will demonstrate the realisation of entangling gate operations between arbitrary ion pairs in a 2d-crystal with fidelities better than 99%. In collaboration with the company Alpine Quantum Technologies (AQT), we will make off-the-shelf 2D ion-crystals available for computational tasks by integrating the traps needed to store the crystals into the quantum computing systems developed by AQT. The control of these first-of-its-kind 2D ion-trap array will be based upon standardised quantum software development kits for this novel computing architecture. The realisation of a universal gate set in a processor with about 100 qubits with all-to-all connectivity will, beyond quantum computation, spearhead novel applications in hybrid digital-analog quantum simulations, quantum metrology and quantum networks.
