USE CASES

Where this instrument fits.

  • Frame quantum algorithm resource discussions
  • Compare circuit depth and qubit pressure
  • Document assumptions before advantage claims
  • Prepare resource-estimate caveats
INPUTS

Required input fields.

  • Logical qubits (required)
  • Circuit depth (required)
  • T-count (required)
  • Target logical error rate (required)
  • Assumed physical error rate (required)
  • Surface-code distance assumption (required)
  • Gate set (required): Clifford+T, Native gates, Fault-tolerant abstract gates

Data handling: this interface uses the L2ET protected same-origin instrument engine. Do not enter confidential, regulated, privileged, incident, medical or sensitive operational data.

METHOD

Formula Workbench logic.

Uses user-entered logical quantities and code-distance assumptions to estimate physical-qubit pressure and runtime-order indicators.

Assumptions

  • Very simplified resource model.
  • Physical qubit estimate is illustrative.
  • Real estimates require architecture-specific compilation and error correction models.
INTERACTIVE INSTRUMENT

Quantum circuit resource estimate.

Use the controls below to generate a preliminary artifact. The output is intentionally bounded and requires human review.
