A2: Generate State $\frac{1}{\sqrt{2}}\lparen\ket{0}-\ket{3}\rparen$

Problem Statement

Implement the operation of preparing the state $\ket{\psi}$ from the zero state on a quantum circuit $\mathrm{qc}$ with $2$ qubits.
The quantum state $\ket{\psi}$ is defined as

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(2)
    # Write your code here:
 
    return qc
