Spacetime replication of continuous variable quantum information [IEEE Information Theory Society, Santa Clara Valley Chapter]
It is well known that no information can be transmitted faster than light, and it is also known that quantum information cannot be cloned or copied arbitrarily. These two "laws" place restrictions on the transmission of information through spacetime, but are there other limitations? The answer is no: the only such restrictions are (1) no-signalling (faster- than-light communication), and (2) no-cloning of quantum information. In this talk, This talk will first provide a brief introduction to some fundamentals of quantum information theory (including the no-cloning theorem and quantum error correction), and then it will show that any process that transmits information through spacetime without violating (1) or (2) is physically realizable as a so-called spacetime information replication task. In particular, this talk will describe how one can succeed at distributing information in seemingly impossible ways using quantum error correction, and showcase new, continuous variable quantum error correcting codes that can efficiently replicate information in spacetime.
