Quantum Noise Transfer: Cross-Device Few-Shot Adaptation Dataset

Paper: Few-Shot Cross-Device Transfer for Quantum Noise Modeling on Real Hardware

Authors: Sahil Al Farib, Sheikh Redwanul Islam, Azizur Rahman Anik

Dataset Description

A real-hardware quantum noise dataset collected from two IBM Quantum devices for studying cross-device transfer learning in quantum error mitigation. Each sample pairs a noisy output distribution (measured on real hardware) with the corresponding ideal output distribution (from noiseless simulation), augmented with device calibration features.

Source Devices

Device	Role	Samples
ibm_fez	Source (Backend A)	85
ibm_marrakesh	Target (Backend B)	85
Total		170

Circuit Composition

Circuit Type	Count	Purpose
Random	40	Structural diversity; generalization
Bell state	15	Two-qubit entanglement; CX error sensitivity
GHZ state	15	Multi-qubit entanglement; error accumulation
QFT	15	Layered gate accumulation; coherent errors

All circuits use 2-5 qubits, depth 2-8, and 8,192 shots per execution.

Usage

from datasets import load_dataset

ds = load_dataset("sahilfarib/quantum-noise-transfer")

# Filter by backend
source = ds["train"].filter(lambda x: x["backend"] == "ibm_fez")
target = ds["train"].filter(lambda x: x["backend"] == "ibm_marrakesh")

print(f"Source samples: {len(source)}")  # 85
print(f"Target samples: {len(target)}")  # 85
