Description
One of the main strengths of the Loop-Tree Duality representation of scattering amplitudes is that it provides a particularly transparent description of the origin of infrared singularities. This talk will review recent progress in elucidating how infrared singularities emerge and cancel at the level of vacuum amplitudes, how finite integrals can easily be constructed, and will also present a complementary approach based on encoding the underlying causal and singular structure in terms of qubits and quantum circuits.
