Quantum Computing in Italia: PoliTo e IQM
Il Politecnico di Torino ha lanciato il primo Master in Quantum Engineering in Italia, con piano di studi che copre algoritmi quantistici, crittografia post-quantistica e hardware a superconduttori.
Nel Q1 2025, PoliTo ha installato un computer quantistico IQM a 5 qubit nel proprio laboratorio, rendendolo uno dei pochi atenei europei con hardware quantistico accessibile agli studenti per esercitazioni pratiche.

Gate implementati in questo visualizzatore
| Gate | Operazione | Effetto su |0⟩ | Effetto su |1⟩ |
|---|---|---|---|
H | Hadamard | |+⟩ = (|0⟩+|1⟩)/√2 | |−⟩ = (|0⟩−|1⟩)/√2 |
X | Pauli-X (NOT) | |1⟩ | |0⟩ |
Y | Pauli-Y | i|1⟩ | −i|0⟩ |
Z | Pauli-Z | |0⟩ | −|1⟩ |
S | Phase S | |0⟩ | i|1⟩ |
CNOT | Controlled-NOT | Flip target se control=|1⟩ | |
Come utilizzare Quantum Circuit Visualizer
Select a gate
Choose a gate from the toolbar: H, X, Y, Z, S or CNOT.
Place the gate on the grid.
Click on a box to place the gate on the qubit and desired step. For CNOT: first click = control qubit, second click = target qubit.
Simulate the Circuit
Click "Simulate" to calculate the exact quantum state and probabilities of basis states.
Try the Bell State
Use "Bell State Load" for a precompiled example of entanglement (H + CNOT).
Suggerimenti
- Use "Bell State Load" to immediately understand how entanglement is constructed with H and CNOT.
- Click on an already placed gate to remove it: works like a toggle.
- Check the table "Implemented Gates" at the bottom of the page for the mathematical effect of each gate on |0⟩ and |1⟩.
Domande frequenti
How many qubits can I use in the circuit?
The viewer supports circuits up to 3 qubits, with up to 8 time steps to build the sequence of gates.
How do I set up a gate CNOT?
Select CNOT from the toolbar, then click first on the control qubit and then on the target qubit in the same step: both clicks must occur in the same temporal column.
What do the percentages represent in the simulation result?
Probabilities of measuring each basis state (e.g. |000⟩, |001⟩) calculated as the square modulus of complex amplitude after applying all gates in the circuit.
Why don't some probabilities add up exactly to 100%?
For rounding of floating-point numbers in complex arithmetic. Values below 0.01% are considered negligible numerical artifacts.
Are my circuits saved or sent to a server?
No, all simulation (matrix multiplication, Kronecker product) happens client-side in the browser: no data leaves the device.
