DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QOART/52/">P
 hoton echo protocols of optical quantum memory</a>\nby S.A. Moiseev as par
 t of Quantum Optics and Related Topics\n\n\nAbstract\nThe main properties 
 of the conventional photon echo quantum memory protocols are analyzed and 
 the results of recent experiments are discussed.  The distinctive features
  of the effect of spectral dispersion and nonlinear interaction of light p
 ulses with resonant atoms on the quantum storage of broadband signal pulse
 s in the studied echo protocols are identified and discussed.  Using the p
 hoton echo area theorem\, closed analytical solutions for quantum memory e
 cho protocols are obtained\, describing the storage of weak and intense si
 gnal pulses\, allowing us to find conditions for the implementation of hig
 h efficiency in echo protocols with strong nonlinear interaction of signal
  and control pulses with atoms. The key existing practical problems and wa
 ys to solve them in realistic experimental conditions are described. Final
 ly\, new optical quantum memory protocols based on the use of long-lived m
 acroscopic quantum coherence are also proposed and their advantages are di
 scussed.\n
