Objective & Setup Objective / Hypothesis (What was the goal?) To test the stability of the H-gate implementation on Qubit 3 under continuous operation for 1 hour, specifically observing the drift in fidelity. Methodology / Setup (What did you do?) Used 5-qubit Rigetti quantum processor. Initialized Qubit 3 to |0⟩. Applied continuous H-gate operations at a rate of 10Hz. Measured fidelity every 5 minutes. Control group run on Qubit 4 (static |0⟩). Temperature: 4K. 3. Findings & Reflection Observations / Results (Raw data, phenomena, outcomes) Fidelity of Qubit 3 dropped from 98.2% to 92.5% over the 60-minute period. Qubit 4 fidelity remained at 99.8%. The degradation rate was non-linear, accelerating after the 40-minute mark. See attached plot QCFS-2025-01-Fidelity.png for full data set. No thermal spikes were recorded. Interpretation / Analysis (What does it mean?) The non-linear degradation suggests an environmental or systemic issue, possibly relating to noise accumulation or increased cross-talk after prolonged excitation. The fidelity loss is significant and requires immediate investigation before scaling the experiment. Next Steps / Actions 1. Rerun experiment on Qubit 5 to eliminate Qubit 3 hardware error possibility. 2. Review ambient noise logs from the 40-minute mark onward. 3. Consult with engineering team regarding potential thermal throttling. Generate Entry Draft Click "Generate Entry Draft" to preview your entry.
