Quantum Anticodes
ChunJun Cao, Giuseppe Cotardo, Brad Lackey
This work introduces a symplectic framework for quantum error correcting codes in which local structure is analyzed through an anticode perspective. In this setting, a code is trea…

Growing Sparse Quantum Codes from a Seed
ChunJun Cao, Brad Lackey
It is generally unclear whether smaller codes can be "concatenated" to systematically create quantum LDPC codes or their sparse subsystem code cousins where the degree of the Tanne…

Universal fault-tolerant logic with heterogeneous holographic codes
Matthew Steinberg, Junyu Fan, Jens Eisert +3
The 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…
