Description
Recent LHC results have demonstrated the possibility to demonstrate that in certain kinematic regions top quark pairs are produced in as an entangled two-qubit system. Spin correlation measurements in top quark pair production at a high-energy linear collider can study a highly entangled quark-anti-quark system in a cleaner and more inclusive fashion, while beam polarization allows for some control over the degree of polarization. The study of top quark pair production in association with an energetic gluon provides an experimental probe of the decoherence of the quantum due to the emission of the gluon. In this contribution, we present the results of a phenomenological study into the feasibility of these novel measurements at linear e+e- colliders.
