This June, the Institute for Quantum Computing (IQC) welcomed 30 of the world’s brightest undergraduates to participate in the Undergraduate School for Experimental Quantum Information Processing (USEQIP). During the week-long program, undergraduate students learned about the wide range of topics in quantum computing from some of Canada’s top quantum academics. From hands on labs, to lectures on quantum information theory, students got a taste of the exciting field of quantum computing.

Optimal coupling for local entanglement extraction from a quantum field

Quantum-Nano Centre, 200 University Ave West, Room QNC 1201 Waterloo, ON CA N2L 3G1

The entanglement structure of quantum fields is of central importance in various aspects of the connection between spacetime geometry and quantum field theory.  However, it is challenging to quantify entanglement between complementary regions of a quantum field theory due to the formally infinite amount of entanglement present at short distances. We present an operationally motivated way of analyzing entanglement in a QFT by considering the entanglement which can be transferred to a set of local probes coupled to the field. In particular, using a lattice approximation to the field theory, we show how to optimize the coupling of the local probes with the field in a given region to most accurately capture the original entanglement present between that region and its complement. This coupling prescription establishes a bound on the entanglement between complementary regions that can be extracted to probes with finitely many degrees of freedom.
