    "abstract": "We describe a method to non-obliviously communicate a 2l-qubit quantum state\nby physically transmitting l+o(l) qubits of communication, and by consuming l\nebits of entanglement and some shared random bits. In the non-oblivious\nscenario, the sender has a classical description of the state to be\ncommunicated. Our method can be used to communicate states that are pure or\nentangled with the sender\u0027s system; l+o(l) and 3l+o(l) shared random bits are\nsufficient respectively.",
