Hyperinvariant Spin Network States -- An AdS/CFT Model from First Principles
Fynn Otto, Refik Mansuroglu, Norbert Schuch +2
We study the existence and limitations of hyperinvariant tensor networks incorporating a local SU(2) symmetry. As discrete implementations of the anti de-Sitter/conformal field the…
Tangent Space Excitation Ansatz for Quantum Circuits
Ji-Yao Chen, Bochen Huang, D. L. Zhou +3
Computing excitation spectra of quantum many-body systems is a promising avenue to demonstrate the practical utility of current noisy quantum devices, especially as we move toward…
Preparation Circuits for Matrix Product States by Classical Variational Disentanglement
Refik Mansuroglu, Norbert Schuch
We study the classical compilation of quantum circuits for the preparation of matrix product states (MPS), which are quantum states of low entanglement with an efficient classical…
The local characterization of global tensor network eigenstates
José Garre Rubio, András Molnár, Norbert Schuch +1
We study the conditions under which Matrix Product States (MPS) or Matrix Product Operators are exact eigenvectors of an extensive local operator, such as a Hamiltonian. By suitabl…
Direct Equivalence between Dynamics of Quantum Walks and Coupled Classical Oscillators
Lilith Zschetzsche, Refik Mansuroglu, András Molnár +1
Continuous time quantum walks on exponentially large, sparse graphs form a powerful paradigm for quantum computing: On the one hand, they can be efficiently simulated on a quantum…
Gauging Quantum Phases: A Matrix Product State Approach
David Blanik, José Garre-Rubio, Norbert Schuch
Utilizing the framework of matrix product states, we investigate gauging as a method for exploring quantum phases of matter. Specifically, we describe how symmetry-protected topolo…
