    Phase kickback: the trick behind quantum algorithms

    The control flips, the target sits still. One strange move that unlocks half the algorithms in the field, built and run in Qiskit.

    From counts to histogram: reading quantum results

    The counts dictionary, the marginal, the distance from ideal. Plain Python for turning quantum output into something you can act on.

    The honest state of quantum in 2026 (NISQ, no hype)

    What quantum genuinely cannot do today, what is actually promising, and why I am still here. No marketing, no doom, just the middle.

    Why your qubits forget: decoherence in plain words

    T1 is the qubit falling down, T2 is the phase slipping away. The two clocks that decide how long your circuit gets to run.

    Qiskit Global Summer School 2026: 4 labs, 473 seconds of real quantum time, 1 badge

    5 IBM badges came from courses. This one came from 4 labs, a grader, and 473 seconds on real quantum hardware. The whole 2 weeks, logged from my own job history.
