Limited Parallelization in Gate Operations Leads to Higher Space Overhead and Lower Noise Threshold
Sai Sanjay Narayanan, Smita Bagewadi, Avhishek Chatterjee
In a modern error corrected quantum memory or circuit, parallelization of gate operations is severely restricted due to issues like cross-talk. Hence, there are enough idle qubits…

Effect of Correlated Errors on Quantum Memory
Smita Bagewadi, Avhishek Chatterjee
Recent results on constant overhead LDPC code-based fault-tolerance against i.i.d. errors naturally lead to the question of fault-tolerance against errors with long-range correlati…

Learning the Influence Graph of a High-Dimensional Markov Process with Memory
Smita Bagewadi, Avhishek Chatterjee
Motivated by multiple applications in social networks, nervous systems, and financial risk analysis, we consider the problem of learning the underlying (directed) influence graph o…
