    "abstract": "We give a proposal for the physical implementation of a quantum shutter. This\nshutter is a mechanism able to close the passage of light through a slit when\npresent. As it must be a quantum mechanical object, able to show superposition,\ninteresting quantum effects are observed. Finally, we review some applications\nof the quantum shutter to build quantum memories and a CNOT gate.",
