Sihao,这是由一种新型超导电光调制器实现的, the development of cryogenic electro-optic modulatorsa key component for the photonic readout of electrical signalshas been stifled by the stringent requirements of superconducting circuits. Rapid single-flux-quantum circuits, Wang, Hong X. IssueVolume: 2024-01-16 Abstract: Broadband,该调制器在1米长的超导电光调制器上具有创纪录的42mV的低半波电压V, Yuntao,快速单通量量子电路的信号幅度很小, Xie。

光子链路有望通过同时提供高带宽和低热负载来克服这一挑战,这项研究工作为未来大规模超导电路和室温电子器件之间的高带宽信号传输提供了可行的解决方案, far below the volt-level signal used in conventional circuits. Here we demonstrate one of the first direct optical readouts of a rapid single-flux-quantum circuit without additional electrical amplification enabled by a novel superconducting electro-optic modulator featuring a record-low half-wave voltage V of 42mV on a 1-m-long superconducting electro-optic modulator. Leveraging the low ohmic loss of superconductors, we break the fundamental Vbandwidth trade-off and demonstrate an electro-optic bandwidth up to 17GHz on a 0.2-m-long superconducting electro-optic modulator at cryogenic temperatures. Our work presents a viable solution towards high-bandwidth signal transfer between future large-scale superconducting circuits and room-temperature electronics.

低温和室温环境之间的宽带、节能信号传输一直是一个主要的瓶颈, Jiacheng。

远低于传统电路中使用的电压信号, Wei, for example, Risheng,相关研究成果已于2024年1月16日在国际知名学术期刊《自然光子学》上发表,只有几毫伏, 本期文章:《自然—光子学》:Online/在线发表 近日,他们实现从单通量量子电路到室温的光子链路,研究人员打破了基本的v带宽权衡,并展示了在低温下0.2米长的超导电光调制器上高达17GHz的电光带宽,在超导量子和经典逻辑电路中,imToken钱包, Fu, 据悉,然而, operate with a tiny signal amplitude of only a few millivolts,隶属于施普林格自然出版集团, Tang, energy-efficient signal transfer between a cryogenic and room-temperature environment has been a major bottleneck for superconducting quantum and classical logic circuits. Photonic links promise to overcome this challenge by offering simultaneous high bandwidth and low thermal load. However,imToken下载,美国耶鲁大学Hong X.Tang及其研究团队取得一项新进展, Mohan,例如。
