Multi-mode bosonic quantum computing with superconducting cavities

预计量子计算机将在无数重要的计算任务中提供显著提高的效率。玻色子系统具有许多基本的和实用的优点，被认为是很有前途的量子计算体系结构。然而，由于存在更多的量子态，为玻色量子计算机开发算法和控制策略通常是具有挑战性的；解决这些挑战是SFU Liu小组的研究重点。这项联盟国际量子基金旨在建立合作，在罗格斯大学查克拉姆集团开发的多模超导腔设备上实施刘团队开发的玻色子算法和控制策略。Chakram Group的设备结合了出色的可控性和高质量因素，因此是实现玻色量子计算的通用平台。作为一个开创性的项目，这项催化剂拨款将支持实现玻色子-量子比特纠缠转换的研究。成功地实现这一方案可以将可以非常高效地产生的玻色纠缠转换为量子比特纠缠，从而可以用于实现广泛的量子计算算法。这将极大地推动实用量子计算机的发展。

The quantum computer is expected to offer dramatically improved efficiency in countless important computational tasks. Bosonic systems have been regarded as promising quantum computing architectures due to many fundamental and practical advantages. However, developing algorithms and control strategies for bosonic quantum computers are generally challenging due to the many more available quantum states; tackling these challenges is the research focus of Lau group at SFU. This Alliance International Quantum grant is intended to establish a collaboration to implement the bosonic algorithms and control strategies developed by Lau group on the multi-mode superconducting cavity device developed by Chakram group at Rutgers University. The device by Chakram group incorporates exceptional controllability and high quality factors, it is thus a versatile platform for implementing bosonic quantum computing. As a pioneer project, this Catalyst grant will support the investigation of realizing bosonic-qubit entanglement conversion. Successfully realizing this scheme can convert the bosonic entanglement, which can be generated extremely efficiently, to qubit entanglement, which can be used to implement a wide range of quantum computing algorithms. This will significantly boost the development of practical quantum computers.
