Abstract

Multi-channel squeezed light sources are extremely desired in establishing quantum metrology systems. Using a single optical fiber parametric amplifier, we prepare a two-channel intensity difference squeezed light source. The directly measured squeezing degrees of the two channels are 3.18 ± 0.18 dB and 2.85 ± 0.18 dB, respectively. The squeezing degree can be further improved by cooling the fiber and reducing injected seeds power and the number of channels can be further increased by injecting more seeds with different wavelengths. The generated two channels of intensity difference squeezing lights can be used in different kinds of quantum measurement and different quantum information processes. Our study is helpful for energy saving and promotion of quantum technology.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
