M28.00001: Progress in superconducting quantum computing at Google Invited Speaker: Kevin J Satzinger Advancing quantum technologies is a multi-faceted enterprise including device design and fabrication, cryogenic and electronic setups, and software and calibration. Two important theaters of experiments are noisy intermediate-scale quantum (NISQ) and quantum error correction (QEC). Here we highlight recent progress by our team in both NISQ and QEC, placing it in the context of our quantum computing roadmap to an error corrected machine. In particular, we focus on recent work realizing toric code and surface code states and characterizing them from two perspectives: topological quantum matter and quantum error correction. |

M28.00002: Esther Hoffman Beller Lectureship (2022): Manufacturing qubits in silicon with atomic precision Invited Speaker: Michelle Y Simmons The realisation of a large-scale error corrected quantum computer relies on our ability to reproducibly manufacture qubits that are fast, highly coherent and stable. The promise of achieving this in a highly manufacturable platform such as silicon requires a deep understanding of the materials issues that impact device operation. In this talk I will demonstrate our progress to engineer every aspect of device behaviour in silicon with atomic precision. This will cover the use of atomic precision lithography to achieve fast, controllable exchange coupling [1], fast, high fidelity qubit initialisation and read-out [2]; low noise all epitaxial gates allowing for highly stable qubits [3]; and qubit control that provide a deep understanding of the impact of the solid-state environment [4] on qubit manufacturability and operation. I will discuss our latest results in analogue quantum simulation [5] and discuss future prospects. |

M28.00003: Challenges and Directions of Quantum Computing with Superconducting Qubits Invited Speaker: Hanhee Paik The field of quantum computing has evolved into a large interdisciplinary community that includes experts from all domains including industry, government, and academia. As a result, we have seen accelerated progress toward understanding the scope of quantum computing, pushing its hardware and software technology, developing applications, and advancing error mitigation/correction protocols. In this talk, I would like to present my view on how to progress technologies for quantum computing systems using key metrics - scale, quality, speed that can indicate the level of performance of a quantum computer. I will overview the recent development of superconducting quantum computing systems and the scientific advances by IBM that enabled to scale superconducting qubits. As quantum computing is becoming a research tool, I will discuss how we can harness the computational power of a quantum computer in machine learning and chemistry by integrating with classical computing resources and using error mitigation. Exploiting classical resources will allow us to extend the computational capacity that the current limits of the quantum hardware can offer. |

M28.00004: High Throughput Cryogenic Characterization of Industry Fabricated Silicon Based Qubit Devices Invited Speaker: otto k zietz Intel fabricates silicon-based quantum computing devices in the same advanced 300mm fab where its next generation process technology is developed. While the creation of a research line for quantum computing allows us to generate a huge number of wafer experiments with 10,000s of devices on each wafer, unlike high-volume CMOS research and development, there exists no corresponding high throughput electrical testing ecosystem for quantum computing. The volume of devices, both quantum dot arrays for qubit formation and ancillary devices for process monitoring and device physics characterization, coupled with the increased complexity of CMOS processing schemes, requires innovation in high throughput cryogenic characterization equipment and techniques. This has led to the development of a first of a kind cryogenic wafer prober capable of device characterization at 1K to enable rapid and statistically significant data collection of both traditional transistor and quantum dot metrics. Here we demonstrate the utility of these high throughput characterization techniques at 1K for fabrication process optimization and yield improvement in addition to optimal device selection for spin qubit formation in our dilution refrigerators at 20mK. |

M28.00005: Trapped Ion Quantum Computing at Quantinuum Invited Speaker: Russell Stutz Decades of progress in trapped ion quantum computing across academia, government labs, and industry enabled some of the world's highest performing systems, improving our understanding of how to move forward in this emerging technology. Quantinuum is pursuing the quantum charge-coupled device (QCCD) architecture of trapped ion quantum computing and recently developed advancements in basic primitive operations of the architecture, ion transport, logical gates, and qubit initialization and detection, helping to define hardware for the next generation quantum computers. In parallel research tracks, current systems are used to gather crucial information about application performance in the areas of quantum error correction and simulations of quantum dynamics. |
