Problem Statement

Implement the operation of preparing the state $\ket{1}$ from the zero state $\ket{0}$ on a quantum circuit $\mathrm{qc}$ with $1$ qubit.

Constraints

Changes in the global phase are ignored.
The submitted code must follow the specified format:

from qiskit import QuantumCircuit
 
 
def solve() -> QuantumCircuit:
    qc = QuantumCircuit(1)
    # Write your code here:
 
    return qc

Hints

Open

You can apply the quantum gate $g$ to the $i$ -th qubit of the quantum circuit $\mathrm{qc}$ as follows:

qc.g(i)

Please refer to Construct circuits - Qiskit for an example circuit configuration and the QuantumCircuit class documunation for a list of available quantum gates.
