SUMMARY:Towards Universal Fault-tolerant Logic on Holographic Codes
DESCRIPTION:\nCharles Cao, Virginia Tech\nThe study of holographic bulk-boundary dualities has led to the construction of novel quantum error correcting codes. Although these codes have shed new light on conceptual aspects of these dualities, they have widely been believed to lack a crucial feature of practical quantum error correction: The ability to support universal fault-tolerant quantum logic. In this work, we introduce a new class of holographic codes that realize this feature. These heterogeneous holographic codes are constructed by combining two seed codes in a tensor network on an alternating hyperbolic tiling. We show how this construction generalizes previous strategies for fault tolerance in tree-type concatenated codes, allowing one to implement non-Clifford gates fault-tolerantly on the holographic boundary. Compared to previous concatenated codes, heterogeneous holographic codes achieve large overhead savings in physical qubits. We will also discuss recent progress on how holographic codes with addressable transversal gates can be built up.\n
