The quantum nature of light possesses many astonishing properties rendering it a promising candidate for novel spectroscopy methods of complex many body phenomena, quantum information processing and subwavelength lithography. Usually its quantum nature is described in the frequency domain and for broadband quantum states of light a quasi continuous wave picture with a well-defined carrier frequency is still applicable. Recent access to subcycle quantum features of electromagnetic radiation [1-3] promises a new class of time-dependent quantum states of light. In view of these developments we formulate a consistent time domain theory of the generation and time resolved detection of few-cycle and subcycle pulsed squeezed states, where the quasi monochromatic picture is not valid anymore and provide a relativistic interpretation of the squeezing process in terms of induced changes in the local flow of time [4]. Our theory enables the use of such states as a resource for novel ultrafast applications in quantum optics and quantum information. [1] C. Riek et al., Science 350, 420 (2015). [2] A.S.
