CQSE and CASTS are launching a seminar this Friday afternoon. Please find the following information for your reference. Time: May 24, 14:30 ~ 15:30 Title: Nuclear quantum memory of a single γ photon Speaker: Prof. Wen-Te Liao 廖文德教授 Department of Physics, National Central University Place: 臺大凝態大樓/物理新館 R716 Rm716, CCMS & New Physics Building, NTU Abstract: A γ-ray-nuclear quantum interface is suggested as a new platform for quantum information processing, motivated by remarkable progresses in γ-ray quantum optics. The main advantages of a γ photon over an optical photon lie in its almost perfect detectability and much tighter, potentially sub-angstrom, focusability. Nuclear ensembles hold important advantages over atomic ensembles in a unique combination of high nuclear density in bulk solids with narrow, lifetime-broadening Mössbauer transitions even at room temperature. This may lead to the densest long-lived quantum memories and the smallest size photon processors. In this talk I will talk about our recent proposal of a technique for γ photon quantum memory through a Doppler frequency comb, produced by a set of resonantly absorbing nuclear targets that move with different velocities [1]. It provides a reliable storage, an on-demand generation, and a time sequencing of a single γ photon. This scheme presents the first γ-photon-nuclear-ensemble interface opening a new direction of research in quantum information science.
