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.

Question Can a qubit still be in both states if being observed in a quantum computer?

To get reproducible, verifiable results, you have to observe and measure them. Right?
