    "abstract": "We define a new measurement of entanglement, the entanglement of projection,\nand find that it is natural to write the entanglements of formation and\nassistance in terms of it. Our measure allows us to describe a new class of\nquantum erasers which restore entanglement rather than just interference. Such\nerasers can be implemented with simple quantum computer components. We propose\nrealistic optical versions of these erasers.",
