Fisher information analysis on quantum-enhanced parameter estimation in electromagnetically-induced-transparency spectrum with single photons
Pin-Ju Tsai, Lun-Ping Yuan, Ying-Cheng Chen
Electromagnetically-induced-transparency (EIT) spectroscopy has been used as a sensitive sensor in quantum metrology applications. The sensitivity of a sensor strongly depends on t…
Memory-based optical polarization conversion in a double-Λ atomic system with degenerate Zeeman states
Yan-Cheng Wei, Sheng-Xiang Lin, Pin-Ju Tsai +1
Optical memory based on electromagnetically induced transparency (EIT) in a double-Λatomic system provides a convenient way to convert the frequency, bandwidth or polarization of o…
Theoretical study on memory-based optical converter with degenerate Zeeman states
Pin-Ju Tsai, Yan-Cheng Wei, Bo-Han Wu +2
We present a theoretical study on the efficiency variation of coherent light conversion based on optical memories using the electromagnetically induced transparency (EIT) protocol…
Quantum storage and manipulation of heralded single photons in atomic quantum memories
Pin-Ju Tsai, Ya-Fen Hsiao, Ying-Cheng Chen
We demonstrate the storage and manipulation of narrowband heralded single photons from a cavity-enhanced spontaneous parametric downconversion (SPDC) source in the atomic quantum m…
Large Cross-Phase Modulations at the Few-Photon Level
Zi-Yu Liu, Yi-Hsin Chen, Yen-Chun Chen +5
We demonstrate an efficient cross-phase modulation (XPM) based on a closed-loop double-Λ system. The property of the double-Λ medium can be controlled by changing the phases of the…
Highly efficient coherent optical memory based on electromagnetically induced transparency
Ya-Fen Hsiao, Pin-Ju Tsai, Hung-Shiue Chen +7
Quantum memory is an important component in the long-distance quantum communication system based on the quantum repeater protocol. To outperform the direct transmission of photons…
Phase-dependent double-Λ electromagnetically induced transparency
Yi-Hsin Chen, Pin-Ju Tsai, Ite A. Yu +2
We theoretically investigate a double-Λ electromagnetically induced transparency (EIT) system. The property of the double-Λ medium with a closed-loop configuration depends on the r…
