| Summary:
Parton showers which can efficiently incorporate quantum interference effects
have been shown to be run efficiently on quantum computers. However, so far
these quantum parton showers did not include the full kinematical information
required to reconstruct an event, which in classical parton showers requires
the use of a veto algorithm. In this work, we show that adding one extra
assumption about the discretization of the evolution variable allows to
construct a quantum veto algorithm, which reproduces the full quantum
interference in the event, and allows to include kinematical effects. We
finally show that for certain initial states the quantum interference effects
generated in this veto algorithm are classically tractable, such that an
efficient classical algorithm can be devised.
