‍Computational Capabilities and Compiler Development for Neutral Atom Quantum Processors: Connecting Tool Developers and Hardware Experts

Neutral Atom Quantum combination of long coherence, scalability, long-range connectivity, native multi-qubit gate support, and the ability to physically rearrange qubits with high fidelity brings a powerful blend of features for next-gen quantum computing. Yet, the design space for compilation taking full advantage of these hardware capabilities is huge. Co-design between hardware and software developers has been identified as crucial to success, and this work facilitates this collaboration by formulating constraints and figures of merit, summarizing the compilation processes and hardware constraints, and discussing relevant and currently available software tools. The work further showcases the value of their pipeline and figures of merit via selected case studies.

False vacuum decay and nucleation dynamics in neutral atom systems

Long-lived oscillations of false and true vacuum states in neutral atom systems

This duo of papers is result of a collaboration between QuEra and NERSC and proposes experimental designs to study the dynamics of false-vacuum decay and bubble nucleation using neutral-atoms analog quantum computers. These topics have consequences in fields ranging from the very small scales of particle and condensed matter physics, to the very large scales of cosmology.

Tailoring Fault-Tolerance to Quantum Algorithms

Co-design is important not only between hardware and algorithms, but also between algorithms and error-correction encoding. This paper advances the latter, proposing compilation schemes that align specific algorithms with favorable quantum error correction schemes. The authors demonstrate their “solve-and-stitch” algorithm via an example of  Clifford Trotter circuits.
