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.

量子计算机有望在无数重要的计算任务中提供显着提高的效率。玻色子系统由于其许多基本的和实用的优点而被认为是有前途的量子计算体系结构。然而，由于更多可用的量子态，为玻色子量子计算机开发算法和控制策略通常具有挑战性;解决这些挑战是SFU Lau小组的研究重点。该联盟国际量子基金旨在建立合作，以实现Lau小组在罗格斯大学Chakram小组开发的多模超导腔器件上开发的玻色子算法和控制策略。Chakram集团的设备具有卓越的可控性和高品质因数，因此它是实现玻色子量子计算的通用平台。作为一个先驱项目，这个催化剂赠款将支持实现玻色子量子比特纠缠转换的研究。成功实现该方案可以将可以极其高效地产生的玻色子纠缠转换为量子比特纠缠，量子比特纠缠可以用于实现广泛的量子计算算法。这将大大推动实用量子计算机的发展。
