Microsoft.Quantum.Preparation namespace

This namespace contains functions and operations for preparing qubits into arbitrary initial states.

Operations

Name	Summary
ApproximatelyPrepareArbitraryState	> [!WARNING]
ApproximatelyPrepareArbitraryStateCP	Given a set of coefficients and a little-endian encoded quantum register, prepares an state on that register described by the given coefficients, up to a given approximation tolerance.
ApproximatelyPrepareArbitraryStateD	Given a set of coefficients and a little-endian encoded quantum register, prepares an state on that register described by the given coefficients, up to a given approximation tolerance.
PrepareArbitraryState	> [!WARNING]
PrepareArbitraryStateCP	Given a set of coefficients and a little-endian encoded quantum register, prepares an state on that register described by the given coefficients.
PrepareArbitraryStateD	Given a set of coefficients and a little-endian encoded quantum register, prepares an state on that register described by the given coefficients.
PrepareChoiState	Prepares the Choi–Jamiołkowski state for a given operation onto given reference and target registers.
PrepareChoiStateA	Prepares the Choi–Jamiołkowski state for a given operation with an adjoint variant onto given reference and target registers.
PrepareChoiStateC	Prepares the Choi–Jamiołkowski state for a given operation with a controlled variant onto given reference and target registers.
PrepareChoiStateCA	Prepares the Choi–Jamiołkowski state for a given operation with both controlled and adjoint variants onto given reference and target registers.
PrepareEntangledState	Pairwise entangles two qubit registers.
PrepareIdentity	Given a register, prepares that register in the maximally mixed state.
PreparePauliEigenstate	Prepares a qubit in the positive eigenstate of a given Pauli operator. If the identity operator is given, then the qubit is prepared in the maximally mixed state.
PrepareQubit	> [!WARNING]
PrepareSingleQubitIdentity	Prepares a qubit in the maximally mixed state.
PrepareUniformSuperposition	Creates a uniform superposition over states that encode 0 through nIndices - 1.
_PrepareAmplitudesFromZeroState	Given a set of coefficients and a little-endian encoded quantum register of unentangled qubits, all of which are in zero state, prepares a state on that register described by the given coefficients. Uses state emulation if supported by the target.
