量子计算硬件公司Quantum Brilliance成立于2019年,由Dr. Andrew Horsley担任CEO,由Dr. Marcus Doherty担任CSO (Chief Science Officer),已获得数千万欧元的融资,计划到2025年在两个关键技术上实现突破,为室温量子计算铺平道路。
“the development of atomically precise techniques for the fabrication of quantum microprocessors and to find new methods for selective initialization, read-out, and manipulation of qubits in quantum computers with multiple processor nodes. ”
Dr. Andrew Horsley在瑞士巴塞尔大学物理系Quantum Optics Lab小组攻读博士学位,导师是Prof. Dr. Philipp Treutlein,该小组国际上首次提出并实验演示了基于原子体系的微波场成像方法。他的博士论文《High resolution field imaging using atomic vapor cell, 基于原子气室的高分辨微波场成像》将这一概念推广到室温热原子体系,大大拓展了应用范围,实现了空间微波场的高分辨相机成像。Dr. Andrew Horsley和杜关祥博士合作,国际上首次报道了基于热原子气室的微波磁场矢量的高分辨成像,成像分辨率达到50微米,微波磁场灵敏度达到1.4 μT/√Hz 。他们的这一创新性方法也被应用于铷原子钟的腔内微波磁场分布表征,他们和瑞士纳沙泰尔的微型化原子钟小组合作,精确测量了原子钟内微波场的模式分布,在EFTF2014年会上报道了这一结果,引起了国际时频同行的浓厚兴趣。
