Live quantum clock built from real QuTech Delft measurements — and the entangled GHZ code does worse than the simple phase probe

🔗 https://ingo6.github.io/quanten-uhr/ A small self-built dashboard that turns real chip measurements from QuTech Delft (Tuna-9/17, via Quantum Inspire) into three side-by-side clocks: Quantum-Time (bit): does the qubit keep its value? (bit-flip channel) - World clock (centre): the real reference both sides are measured against - Quantum-Qubit (phase): two separate real measurements — - a shallow phase probe (D=100) → ≈ +7 pp, helps - an entangled GHZ code (D=300) → ≈ −15 pp, below break-even (hurts) Multilingual (DE/EN/FR/ES, switch top-left), built screen-reader-friendly, with a live online / maintenance / offline badge. Refreshes every few minutes, fully token-free. 🔗 https://ingo6.github.io/quanten-uhr/ submitted by /u/Sufficient-Main-4101 [link] [comments]
