Demonstrating Noise-adapted Quantum Error Correction With Break-Even Performance
Vismay Joshi, Anubhab Rudra, Sourav Dutta +2
The promise of quantum computing is closer to reality today than ever before, thanks to rapid progress in the development of quantum hardware. Even as qubit lifetimes and gate fide…
Smallest quantum codes for amplitude damping noise
Sourav Dutta, Aditya Jain, Prabha Mandayam
We describe the smallest quantum error correcting (QEC) code to correct for amplitude-damping (AD) noise, namely, a 3-qubit code that corrects all the single-qubit damping errors.…
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…
Expedited Noise Spectroscopy of Transmon Qubits
Bhavesh Gupta, Vismay Joshi, Udit Kandpal +3
There has been tremendous progress in the physical realization of quantum computing hardware in recent times, bringing us closer than ever before to realizing the promise of quantu…
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…
Fault tolerance against amplitude-damping noise using Bacon-Shor codes
Long D. H. My, Akshaya Jayashankar, Prabha Mandayam +1
Designing efficient fault tolerance schemes is crucial for building useful quantum computers. Most standard schemes assume no knowledge of the underlying device noise and rely on g…
