Obstacles to State Preparation and Variational Optimization from Symmetry Protection
Sergey Bravyi, Alexander Kliesch, Robert Koenig +1
Local Hamiltonians with topological quantum order exhibit highly entangled ground states that cannot be prepared by shallow quantum circuits. Here, we show that this property may e…

Quantum Error-Detection at Low Energies
Martina Gschwendtner, Robert Koenig, Burak Şahinoğlu +1
Motivated by the close relationship between quantum error-correction, topological order, the holographic AdS/CFT duality, and tensor networks, we initiate the study of approximate…
