DESCRIPTION: The last years have seen a rapid development of applications 
 of quantum computationto quantum field theory. The first quantum algorithm
 s for simulation of scattering havebeen proposed in the context of scalar 
 and fermionic theories\, requiring thousands oflogical qubits. These algor
 ithms are not suitable to simulate scattering of incomingbound states\, as
  the initial state preparation relies typically on adiabaticallytransformi
 ng wavepackets of the free theory into wavepackets of the interactingtheor
 y. In this talk\, I will present a strategy to excite wavepackets of the i
 nteracting theorydirectly from the vacuum of the interacting theory\, allo
 wing for preparation of statesof composite particles that can be taken as 
 initial states of a scattering simulation. Thisis the first step towards d
 igital quantum simulation of scattering of bound states.The approach is ba
 sed on the Haag-Ruelle scattering theory\, which provides a way toconstruc
 t creation and annihilation operators of a quantum field theory in a full\
 , nonperturbative framework. As an example\, I will consider a scalar theo
 ry in one spacedimension displaying a composite particle in its spectrum
