Exact log-depth preparation of highly entangled matrix product states
Keisuke Murota, Frédéric Sauvage, Marco Ballarin +2
Preparing matrix product states (MPS) on a quantum device is a key subroutine in many quantum algorithms. The most competitive methods, based on the renormalisation group, prepare…
Characterization of variational quantum algorithms using free fermions
Gabriel Matos, Chris N. Self, Zlatko Papić +2
We study variational quantum algorithms from the perspective of free fermions. By deriving the explicit structure of the associated Lie algebras, we show that the Quantum Approxima…
Quantifying the efficiency of state preparation via quantum variational eigensolvers
Gabriel Matos, Sonika Johri, Zlatko Papić
Recently, there has been much interest in the efficient preparation of complex quantum states using low-depth quantum circuits, such as Quantum Approximate Optimization Algorithm (…
