Dinfio Documentation — Function Reference: quantum_circuit::set_psi()

Module quantum → Class quantum_circuit → set_psi()

Description

Set the state \(\ket{\psi}\). This function takes care of normalisation so you don't have to do it yourself

quantum_circuit::set_psi(psi)

Parameters

psi (matrix) — The matrix of state \(\ket{\psi}\). The dimension must be \(2^N\times1\), where \(N\) is the total qubits of the circuit

Return Value

quantum_circuit — Returns the instance of class quantum_circuit

Usage Example

import quantum
 
qc = quantum_circuit(1)
 
psi = matrix([[0.5],
              [0.5]])
 
qc.set_psi(psi)
qc.print_statevector()
 
 
' Output:
' [ 0.707107 + 0i
