Maximizing Qubit Throughput under Buffer Decoherence and Variability in Generation
Padma Priyanka, Avhishek Chatterjee, Sheetal Kalyani
Quantum communication networks require transmission of high-fidelity, uncoded qubits for applications such as entanglement distribution and quantum key distribution. However, curre…
Expander qLDPC Codes against Long-range Correlated Errors in Memory
Yash Deepak Kashtikar, Pranay Mathur, Sudharsan Senthil +1
Fault-tolerance using constant space-overhead against long-range correlated errors is an important practical question. In the pioneering works [Terhal and Burkard, PRA 2005], [Alif…
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…
