Experimental Realization of Spin Liquids in a Programmable Quantum Device

ORAL

Abstract

The advent of widely available computing power has spawned a whole research field that we now call computational physics. Today, we may be on the cusp of a similar paradigm shift as programmable qubit devices enable one to run experiments on a platform of actual physical quantum states. Here we use the commercially available D-Wave DW-2000Q device to build and probe a state of matter that has not been observed or fabricated before. The topological phase that we build has been widely sought for many years and is a candidate platform for quantum computation. While we cannot observe the full quantum regime due to the limitations of the current device, we do observe unmistakable signatures of the phase in its classical limit at the endpoint of the quantum annealing protocol. In the process of doing so, we identify additional features that a programmable device of this sort would need in order to implement fully functional topological qubits. It is a testament to technological progress that a handful of theorists can observe and experiment with new physics while being equipped only with remote access to a commercial device.
