This is a proprietary Madjik metric. Its methodology is a trade secret; the values are available through the API.
Quantum configuration
Every quantum calculation of this metric, with the machine and circuit setup it runs on. Hardware values come from real IBM quantum computers; simulator values from a classical simulation of the same kind of circuit.
| Method | Quantum computing on hardware (quant-hw) |
|---|---|
| Provider | IBM Quantum Platform (Open plan) |
| Machine | ibm_marrakesh (156 qubits) |
| Machine type | superconducting QPU (IBM Heron) |
| Qubits used | 6 |
| Circuits per run | 1 |
| Shots per run | 1,024 |
| Circuit depth | 5 |
| Two-qubit gates | 0 |
| Gate basis | cz, rz, sx, x (IBM Heron native) |
| Algorithm | RY angle-encoded asset-selection circuit, most frequent bitstring selects the portfolio |

| Hardware runs | 2 |
| Last run | 2026-10-05T06:30:54 |
| IBM job id | db1k3arid5ic73er8bp0 |
| How measured | IBM job record (transpiled circuit stats) |
| Method | Quantum computing simulated (quant-sim) |
|---|---|
| Provider | Qiskit Aer simulator (IBM open-source software) on Google Cloud |
| Machine | aer_simulator |
| Machine type | classical simulator (CPU, noise-free) |
| Qubits used | 6 |
| Circuits per run | 1 |
| Shots per run | 1,024 |
| Circuit depth | 2 |
| Two-qubit gates | 0 |
| Gate basis | u, cx (Aer, flattened) |
| Algorithm | RY angle-encoded asset-selection circuit, most frequent bitstring selects the portfolio |
| Profile | native (primary) circuit |
| Error mitigation | none (noise-free simulation) |
| How measured | recorded circuits, compiled to u/cx |
| Note | primary value of the metric: this circuit is the published quant-sim calculation |
Personal metrics: figures are the maximum across submitted portfolios (circuit size follows portfolio size). Machine qubits is the size of the whole chip; qubits used is what this calculation needs.
