Function estimatePhase

estimatePhase(
    numControl: number,
    unitaryName: string,
    eigenstateType?: "i" | "-i" | "+" | "-" | "0" | "1",
    unitaryParams?: { angle?: number; [key: string]: unknown },
): Circuit
Estimates the phase of a specific eigenstate preparation.

This convenience function combines eigenstate preparation with phase estimation for common use cases. It automatically prepares known eigenstates and applies QPE.
Parameters
- numControl: number
  Number of control qubits (precision)
- unitaryName: string
  Unitary operator to analyze
- eigenstateType: "i" | "-i" | "+" | "-" | "0" | "1" = '0'
  Type of eigenstate to prepare
- OptionalunitaryParams: { angle?: number; [key: string]: unknown }
  Optional unitary parameters
Returns Circuit
Circuit ready for phase estimation measurement
