Abstract To advance the full potential of quantum networks one should be able to distribute resources over long distances at appreciable rates. As a consequence, all components in such need have large multimode capacity manipulate photonic states. Towards this end, memory with capacity, especially operating telecom wavelength, remains an important challenge. Here we optimize preparation atomic frequency combs and demonstrate spectro-temporally multiplexed 10-m-long cryogenically cooled...

Interference of multiple photons via a linear-optical network has profound applications for quantum foundation, metrology, and computation. Particularly, boson sampling experiment with moderate number becomes intractable even the most powerful classical computers. Scaling up from small-scale experiments requires highly indistinguishable single photons, which may be prohibited many physical systems. Here we report time-resolved multiphoton interference by using not overlapping in their...

Abstract In this study, the on‐chip generation of microwave signals are proposed for controlling nearby quantum bits in a low‐temperature environment, utilizing superconducting logical and RF components. To achieve enhanced amplitude microwave, single flux (SFQ) pulse pairs employed, which can have either same or reversal polarity, serving as basic elements generator. The SFQ then combined wave‐shaped by using combining filter, finally outputs desired with narrow line‐width. signal...
