# $\lvert -\rangle$ (Qiskit)
[[minus-state|Minus state $\lvert -\rangle$]] implementation using Qiskit. The $\lvert -\rangle$ state is prepared by applying an [[x-gate|X gate]] followed by a [[h-gate|Hadamard gate]] to $\lvert 0\rangle$.

```python
from qiskit import QuantumCircuit
from qiskit.quantum_info import Statevector

qc = QuantumCircuit(1)
qc.x(0)  # |0> -> |1>
qc.h(0)  # |1> -> |-> = (|0> - |1>) / sqrt(2)
print(Statevector(qc))
# Statevector([ 0.70710678+0.j, -0.70710678+0.j], dims=(2,))
