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…
Shot-noise reduction for lattice Hamiltonians
Timo Eckstein, Refik Mansuroglu, Stefan Wolf +4
Efficiently estimating energy expectation values of quantum lattice systems on quantum computers is a crucial subroutine for various quantum algorithms, which can lead to significa…
Complexity of Quadratic Bosonic Hamiltonian Simulation: -Completeness and -Hardness
Lilith Zschetzsche, Refik Mansuroglu, Norbert Schuch
The computational complexity of simulating the dynamics of physical quantum systems is a central question at the interface of quantum physics and computer science. In this work, we…
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…
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…
Efficient Quantum Cooling Algorithm for Fermionic Systems
Lucas Marti, Refik Mansuroglu, Michael J. Hartmann
We present a cooling algorithm for ground state preparation of fermionic Hamiltonians. Our algorithm makes use of the Hamiltonian simulation of the considered system coupled to an…
