EstimateEnergy operation
Performs state preparation by applying a
statePrepUnitary
on an automatically allocated input state
phase estimation with respect to qpeUnitary
on the resulting state
using a phaseEstAlgorithm
.
operation EstimateEnergy (nQubits : Int, statePrepUnitary : (Qubit[] => Unit), qpeUnitary : (Qubit[] => Unit is Adj + Ctl), phaseEstAlgorithm : ((Microsoft.Quantum.Oracles.DiscreteOracle, Qubit[]) => Double)) : Double
Input
 nQubits
 Int
Number of qubits used to perform simulation.
 statePrepUnitary
An oracle representing state preparation for the initial dynamical generator.
Input: Qubit[]
Output: Unit
 qpeUnitary
An oracle representing a unitary operator $U$ representing evolution for time $\delta t$ under a dynamical generator with ground state $\ket{\phi}$ and ground state energy $E = \phi\,\delta t$.
 Functors

Adjoint Controlled
Input: Qubit[]
Output: Unit
 phaseEstAlgorithm
An operation that performs phase estimation on a given unitary operation. See iterative phase estimation for more details.
Output
Double
An estimate $\hat{\phi}$ of the ground state energy $\phi$ of the ground state energy of the generator represented by $U$.
