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…

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…
