From QCCD Trapped-Ion Hardware to Quantum Compilers: Capabilities, Architectures, and Compilation

Shuttling-based trapped-ion quantum computers (QCCD) rank among the most mature hardware platforms. Existing and envisaged devices exhibit architectural differences in terms of register layout and connectivity. Platform-specific compilers are required to translate quantum circuits into resource-optimized hardware-level...

Hardware-aware Compilation for Different Quantum Computing Platforms

Know Your Qubits, Know Your Users: Personas for Quantum Software

The advancement of quantum hardware and the intricacies of quantum computing make well-designed quantum software increasingly necessary. Due to the interdisciplinarity of the field, it is crucial to understand the perspectives and specific needs of involved stakeholders, for example, to balance the desired level of abs...

Why Are We Unrolling? The Importance of Structured Quantum Programs for Compilation

This work presents important patterns and algorithms from fault-tolerant quantum applications which admit a structured representation that it is argued is crucial to preserve, and sets a challenge to the community to compile such representations without unrolling them into straight-line quantum circuits.

Teaching Quantum Design Automation with Block-Based Programming

As quantum circuits grow beyond small toy examples, preparing them for execution on physical devices becomes increasingly complex. Design automation is therefore essential for scalable quantum computing: Compilation procedures optimize resource requirements and transform circuits to a format compatible with specific ha...
