Bias-Preserving Gates and Quantum Error Correction With Dual-Rail Cat Codes
Debjyoti Biswas, Nikhil Sharma, Alberto Salvador +4
Scalable fault-tolerant quantum computation requires quantum error-correcting codes that simultaneously support universal logical operations, suppress hardware-specific noise, and…
Universal syndrome-based recovery for noise-adapted quantum error correction
Debjyoti Biswas, Prabha Mandayam
Quantum error correction (QEC) is an essential tool for quantum computing that enables reliable information processing in the presence of noise. Syndrome measurements play a centra…
Noise-adapted qudit codes for amplitude-damping noise
Sourav Dutta, Debjyoti Biswas, Prabha Mandayam
Quantum error correction (QEC) plays a critical role in preventing information loss in quantum systems and provides a framework for reliable quantum computation. Identifying quantu…
Noise-adapted Quantum Error Correction for Non-Markovian Noise
Debjyoti Biswas, Shrikant Utagi, Prabha Mandayam
We consider the problem of quantum error correction (QEC) for non-Markovian noise. Using the well known Petz recovery map, we first show that conditions for approximate QEC can be…
Noise-adapted recovery circuits for quantum error correction
Debjyoti Biswas, Gaurav M. Vaidya, Prabha Mandayam
Implementing quantum error correction (QEC) protocols is a challenging task in today's era of noisy intermediate-scale quantum devices. We present quantum circuits for a universal,…
