Coset Lifted Product Codes: Constructing Quantum LDPC Codes from Non-Normal Subgroup Actions
Rajendra Prasad Rajpurohit, V. Lalitha, Shayan Srinivasa Garani
We introduce coset lifted product (CLP) codes, a family of quantum LDPC codes that combine the protograph structure of lifted product codes with the coset action of Aydin, Tamo, an…
Maximally recoverable codes with locality and availability
Umberto Martínez-Peñas, V. Lalitha
In this work, we introduce maximally recoverable codes with locality and availability. We consider locally repairable codes (LRCs) where certain subsets of symbols belong eac…
Maximally Recoverable Codes with Hierarchical Locality: Constructions and Field-Size Bounds
D. Shivakrishna, Aaditya M. Nair, V. Lalitha
Maximally recoverable codes are a class of codes which recover from all potentially recoverable erasure patterns given the locality constraints of the code. In earlier works, these…
Rack-Aware Cooperative Regenerating Codes
Shreya Gupta, V. Lalitha
In distributed storage systems, cooperative regenerating codes tradeoff storage for repair bandwidth in the case of multiple node failures. In rack-aware distributed storage system…
On Gradient Coding with Partial Recovery
Sahasrajit Sarmasarkar, V. Lalitha, Nikhil Karamchandani
We consider a generalization of the gradient coding framework where a dataset is divided across workers and each worker transmits to a master node one or more linear combinatio…
Secure Regenerating Codes for Reducing Storage and Bootstrap Costs in Sharded Blockchains
Divija Swetha Gadiraju, V. Lalitha, Vaneet Aggarwal
Blockchain is a distributed ledger with wide applications. Due to the increasing storage requirement for blockchains, the computation can be afforded by only a few miners. Sharding…
