During pulse sweeps, such as in waveform calibrations, utilize parametric pulses with varying amplitudes to efficiently reuse waveform memory. Less memory is available for measurement channels. |
| 8019 | For channel {}{}, Final channel time exceeds max time ({} > {}) | Reduce the total length of pulse sequence on the specified channel. |
| 8020 | Sequence exceeded maximum allowable circuit length | Circuit too long, reduce length of circuit. |
| 8021 | Acquires have durations of different length | Set acquire operations to have the same length. |
| 8022 | Pulse {} has too many samples ({} > {}) | Reduce the number of samples in the specified pulse. |
| 8023 | {0} {1} is an invalid entry. {0} should be a nonnegative integer | Make the entry a positive integer. |
| 8024 | At most one acquire currently supported per acquistion channel | Use only one acquire command per channel. |
| 8026 | Supplied qubits ({0}) in acquire are not valid | Fix the qubits specified in the acquire commands. |
| 8027 | Channel specified: {} is not available | Channel does not exist on system. |
| 8029 | Repetition time ({0}) not supported | Repetition time must be changed to a supported value. |
| 8030 | Repetition delay ({0}) not supported | The delay is not supported. |
| 8031 | Submitted job is too long | Reduce the length of the job. |
| 8033 | Qobj "type" not provided in "config" | Add type to qobj['config']. |
| 8035 | Instruction "{0}" at timestep {1}dt overlaps with instruction "{2}" at timestep {3}dt on channel "{4}" | Two instructions cannot be played at the same time on a channel. |
| 8036 | All measure(circuit) and acquire(pulse) instructions must align to a 16 sample boundary. Measurements may be impacted by delays which have non-multiple of 16 durations | Due to hardware limitations, measure and acquire instructions must occur at 16 sample multiples. |
| 8037 | ESP readout is not enabled on this device | Set use_measure_esp=False or remove from run options. |
| 8038 | A timing error occurred during execution of the input circuits. | Try increasing the selected 'rep_delay' value or reducing the number of measurements/resets within your circuits. |
| 8039 | A combination of pulses on the logical channels is exceeding the hardware output due to internal usage of hardware output. | Try lowering the amplitude of your input pulses. |
| 8040 | It is likely you requested acquisitions to be stored into memory slots without configuring your program with those memory slots. | Check your classical register sizes. |
| 8041 | The norm of one of the requested waveforms exceeded 1.0 for some samples. Please decrease the waveform amplitude and try again | Lower the amplitudes of the input pulses. |
| 8042 | Invalid pulse parameters for one of the waveforms. Check the amplitude limits and type constraints | Verify the pulse input parameters. |
| 8043 | Delays must be a multiple of {0} samples | Ensure the pulse duration parameter is valid. |
| 8044 | Number of samples is less than the minimum pulse duration of {0} samples | Verify that the duration of all pulses meets or exceeds the minimum pulse duration. If necessary and possible, you may consider zero-padding the start/end of very short pulses such that they meet or exceed the minimum duration. |
| 8045 | A buffer overflow occurred during result collection. | Reduce the number of shots or measurements, or increase the rep_delay |
| 8047 | A pulse scheduling conflict occurred. | Increase the lengths of any short pulses, and/or insert more delay between them. |
| 8048 | A pulse or combination of simultaneous pulses exceeded the available DAC amplitude range. | Reduce the amplitudes of any large or overlapping pulses, compensating by making them longer if needed. |
| 8055 | Job payload being loaded is too large. | Reduce the length of the program data being loaded. |
| 8056 | An error occurred during a QIC subsystem operation. | |
| 8057 | An error occurred during a QIC adapter operation. |

| Error code | Message | Solution |
|---|---|---|
| 9605 | Failed to load program into HAL component | Make your program smaller. For example, reduce the number of circuits (by splitting the job into multiple jobs) or instructions it requires. |
| 9614 | classical register has length {} but attempted to save into the {} index | Ensure the intended register is correct and available. |
| 9615 | No classical reg for the measure on circuit {} | Ensure the classical register exists |
| 9999 | Internal error | Contact IBM Quantum via Slack(opens in a new tab) for help. |
