Generic perturbations of a Fermi liquid create noise in the form of numerous particle-hole pairs. In the talk I will show that it is possible to excite particles from a Fermi sea in a noise-free fashion by electromagnetic pulses of a simple form. The resulting many-body states are characterized by one or several particles excited above the Fermi surface accompanied by no disturbance below it. These excitations are a realization of vertex operators appearing in conformal field theory. Finally I will discuss potential applications in creating entangled electron hole pairs.
