2. Hardware — Marrakesh Heron lasers / microwaves / cryogenic sensors

This scan treats ibm_marrakesh as a laser/sensor-instrumented quantum measurement system mapping control pulses → entangled quantum state → classical channel outcomes.

Microwave drive lines: XY microwave pulses enact native single-qubit sx/x rotations on Heron qubits.
Laser / optical timing plane: Coherent pulse-control electronics with optical-grade timing/reference infrastructure synthesize drive waveforms across the Heron actuator layer.
CZ entangling actuators: Native cz gates on the Heron coupling graph implement coupled-channel / network-link probes after transpile.
Pulse control: SamplerV2 executes scheduled pulse sequences from transpiled OpenQASM (rz/sx/x/cz/measure).
Dispersive readout: Each qubit’s state is read via dispersive resonator response (IQ demodulation → bit).
Cryogenic sensors: Dilution-refrigerator cryogenic amplification senses weak readout tones; resulting bitstrings are the scanned measurement-channel dataset.

System: IBM Quantum Heron processor — ibm_marrakesh (156 qubits)

Theme: radio-wave / frequency / network / data-connection signatures from the live scan (prefix bins, Hamming spectra, FFT of P(outcome), bit–bit correlations).

3. Method — SamplerV2 pubs · transpile · scan pathway

Live scan: REAL ibm_marrakesh SamplerV2 measurements (bitstrings / counts / entropy / spectra). Marrakesh Heron lasers, microwave drives, cryogenic sensors, and dispersive readout ran this space / radio / frequency / network / data-connection scan end-to-end. Channel bins = bitstring prefixes / Hamming weight / FFT of the outcome probability vector.

Pathway: IAM + POST https://quantum.cloud.ibm.com/api/v1/jobs · program_id=sampler · params.version=2 · transpiled for Heron (rz/sx/x/cz) · solo submit (no Toolbox dual-submit) · private encrypted land only · wwwroot not published.

Short: 4 pubs × 8192 shots on 8 logical qubits
Long: 8 pubs × 16384 shots on 8 logical qubits (follow-up to short)
Analysis: Shannon entropy, 4-bit prefix channel bins, Hamming-weight spectra, FFT spectral peaks of P(outcome), Pearson bit–bit correlations
Scan map: Channel/frequency bin ↔ prefix or Hamming bin; Broadband ↔ Hadamard; Coupled/network ↔ CZ chain; Carrier-tagged ↔ RZ phases; Echo ↔ structured low-entropy return; Spectrum ↔ FFT of P(outcome) index

Top bitstring: 11110000 count 2695 (16.449%)
Runner-up: 11111000 count 2687 (16.400%); 11110100 count 1704 (10.400%)
Dominant prefix bin: 1111 with 10703 shots (~65.3% of pub)
Next prefixes: 1110:2366, 1101:1505

`hamming_probe`	7.427879	7.416122	-0.011757

Shared pubs are stable: entropy deltas are small (|Δ| ≲ 0.03). Long scan adds four new channel probes; echo_probe dominates as the structured low-entropy channel.
