On the order problem in construction of unitary operators for the Variational Quantum Eigensolver

19 May 2020 Izmaylov Artur F. Díaz-Tinoco Manuel Lang Robert A.

One of the main challenges in the Variational Quantum Eigensolver (VQE) framework is construction of the unitary transformation. The dimensionality of the space for unitary rotations of $N$ qubits is $4^N-1$, which makes the choice of a polynomial subset of generators exponentially difficult process... (read more)
