Towards a variational Jordan–Lee–Preskill quantum algorithm
Towards a variational Jordan–Lee–Preskill quantum algorithm
Rapid developments of quantum information technology show promising opportunities for simulating quantum field theory in near-term quantum devices. In this work, we formulate the theory of (time-dependent) variational quantum simulation of the 1+1 dimensional $\lambda \phi^4$ quantum field theory including encoding, state preparation, and time evolution, with several numerical simulation …
