Building Bulk Geometry from the Tensor Radon Transform
ChunJun Cao, Xiao-Liang Qi, Brian Swingle +1
Using the tensor Radon transform and related numerical methods, we study how bulk geometries can be explicitly reconstructed from boundary entanglement entropies in the specific ca…
The ghost in the radiation: Robust encodings of the black hole interior
Isaac H. Kim, Eugene Tang, John Preskill
We reconsider the black hole firewall puzzle, emphasizing that quantum error-correction, computational complexity, and pseudorandomness are crucial concepts for understanding the b…
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…
