    "abstract": "We consider the problem of hiding sender and receiver of classical and\nquantum bits (qubits), even if all physical transmissions can be monitored. We\npresent a quantum protocol for sending and receiving classical bits\nanonymously, which is completely traceless: it successfully prevents later\nreconstruction of the sender. We show that this is not possible classically. It\nappears that entangled quantum states are uniquely suited for traceless\nanonymous transmissions. We then extend this protocol to send and receive\nqubits anonymously. In the process we introduce a new primitive called\nanonymous entanglement, which may be useful in other contexts as well.",
