There are two possibilities to prepare a qubit in a particular state like $ | - \rangle $ in Qiskit.
The first approach is using the initialize function:
qc = QuantumCircuit(1) initial_state = [1/sqrt(2),-1/sqrt(2)] qc.initialize(initial_state, 0)
The second approach is using standard quantum gates:
qreg_q = QuantumRegister(1, 'q') creg_c = ClassicalRegister(1, 'c') qc = QuantumCircuit(qreg_q, creg_c) qc.x(qreg_q) qc.h(qreg_q)
Are these two possibilities different? What is the "best practice" for preparing an arbitrary qubit state?
Is there a comparable initialize function in Q#?
