Classical temporal imaging enables manipulation of temporal optical signals in a manner similar to manipulation of optical images in spatial domain. The concept of temporal imaging relies on the notion of space-time duality with frequency dispersion of the medium playing the role of diffraction and quadratic phase modulation in time acting as a time lens. In this talk we shall generalize classical temporal imaging to quantum temporal imaging viable for non-classical states of light. As an example, we shall consider quantum temporal imaging of broadband squeezed light produced by a travelling-wave optical parametric amplifier, and demonstrate a possibility of noiseless temporal magnification or contraction keeping intact non-classical properties of such light.
