B: Generate Minus state

Problem Statement

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

The minus state $\ket{-}$ is defined as

Constraints

• Global phase is ignored in judge.
• The submitted code must follow the specified format:

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