How to implement the cross term (multi-qubit) in the square of the finite difference operator?
I am trying to simulate the Hamiltonian evolution of the 1+1D $\lambda\phi^4$ scalar field theory by digitising it and encoding on a quantum computer. The process of digitising is taken from this pape …

How to implement the cross term (multi-qubit) in the square of the finite difference operator?
After some looking into this, the two operator product is a tensor product instead of normal matrix multiplication. For a 2 qubit system, operator $\phi(1)$ is represented as a matrix acting on the fu …
