How is the T gate expressed in Qiskit?
The T gate is expressed in Qiskit as.t (): qc = QuantumCircuit(1) qc.t(0) # T gate on qubit 0 qc.draw() It is a rotation around the z axis by θ = π / 4, and so is expressed mathematically as Rz(π / 4) = eiπ / 8 Z. In the following we assume that the H and T gates are effectively perfect.
How to create a short circuit in Qiskit?
In Qiskit, we can create a short circuit to verify this: Let’s see the result of the above circuit. Note: Here we use plot_bloch_multivector () which takes a qubit’s statevector instead of the Bloch vector. We can indeed see the state of the qubit is | 1⟩|1⟩ as expected.

How to create a quantum circuit in Qiskit?
Quantum circuits. The object at the heart of Qiskit is the quantum circuit. Here’s how we create one, which we will call qc. from qiskit import QuantumCircuit qc = QuantumCircuit() This circuit is currently completely empty, with no qubits and no outputs.
What do you need to know about Qiskit?
Specifically, we want the state vector. This is the vector for a Bell state (|00⟩+|11⟩)/√2 ( | 00 ⟩ + | 11 ⟩) / 2, which is what we’d expect given the circuit. While we have a nicely defined state vector, we can show another feature of Qiskit: it is possible to initialize a circuit with an arbitrary pure state.
