Portfolio Depeg Exposure (M10034)
| Metric ID | M10034 |
|---|---|
| Category | personal |
| Access | personal — computed per customer from the portfolio they submit; see Personal metrics |
| Classification | proprietary |
| Tier | enterprise |
| Computation | Classical + Quantum (hardware) + Quantum (simulated) |
| Computed by | Black Belt Labs |
| Freshness | fresh |
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_fez,ibm_kingston (156 qubits) |
| Machine type | superconducting QPU (IBM Heron) |
| Qubits used | 1 |
| Circuits per run | 1 |
| Shots per run | 8,192 |
| Circuit depth | 5 |
| Two-qubit gates | 0 |
| Gate basis | cz, rz, sx, x (IBM Heron native) |
| Algorithm | shallow hardware profile of the personal twin (direct readout, small QAOA grid) |
| Profile | shallow |

| Last run | 2026-10-08T07:10:24 |
| How measured | recorded circuits compiled with the ibm_fez device model (estimate of the submitted circuits) |
| Note | maximum over 4 portfolios; circuits differ with portfolio size |
| Method | Quantum computing simulated (quant-sim) |
|---|---|
| Provider | Qiskit Aer simulator (IBM open-source software) on Google Cloud |
| Machine | aer_simulator |

| Shots per run | 4,096 |
| Circuit depth | 2 |
| Two-qubit gates | 0 |
| Gate basis | u, cx (Aer, flattened) |
| Algorithm | personal_core twin (see methodology) |
| Profile | full |
| Error mitigation | none (noise-free simulation) |
| How measured | recorded circuits, compiled to u/cx |
| Note | maximum over 4 portfolios |
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.
