Introduction to stabilizer measurements

The following code blocks measure a Z stabilizer as described by Fowler et al (2012). This type of circuit is central to the field of quantum error correction via the idea of a Stabilizer Code.

This circuit is constructed such that the central "measure" qubit will be in the \(|1\rangle\) state if an odd number of the four surrounding "data" qubits (named a-d in the figure) have a bit-flip error (corresponding to an X gate).

Stabilizer measurements on a small grid

The examples below demonstrate a single Z stabilizer, similar to the image above.

Without noise

In a perfectly noiseless Z stabilizer, all qubits will remain in the \(|0\rangle\) state.

data_qubits = [cirq.NamedQubit('data_' + str(x)) for x in 'abcd']
measure_qubit = cirq.NamedQubit('_meas')
stabilizer_circuit = cirq.Circuit(
    *[cirq.CX(data_qubit, measure_qubit) for data_qubit in data_qubits],
    cirq.measure(measure_qubit, key='meas'),
)

print(f'Z-stabilizer circuit:')
print('========================')
print(stabilizer_circuit)

simulator = cirq.Simulator()
result = simulator.run(stabilizer_circuit, repetitions=100)
ax = cirq.plot_state_histogram(result)
plt.show(ax)

With fixed noise

If one of the qubits is flipped, the measure qubit will also flip to match the parity of the data qubits.

random_data_qubit = random.choice(data_qubits)
stabilizer_circuit_with_error = cirq.X(random_data_qubit) + stabilizer_circuit

print('========================')
print(stabilizer_circuit_with_error)

                           │
data_d: ───────────────────@───────────────

result = simulator.run(stabilizer_circuit_with_error, repetitions=100)
ax = cirq.plot_state_histogram(result)
plt.show(ax)

With hardware noise on the QVM

With hardware-like noise, the stabilizer circuit becomes much more interesting. An arbitrary error could occur at any point:

On a data qubit before or after the CNOT
On the measure qubit before or after the CNOTs
On the measure qubit between CNOTs
Multiple errors in any combination of the above locations

The only indication of that error comes from the output of the measure qubit. By creating a grid of stabilizers and observing how they change over time, it's possible to decode when and where errors occured and compensate for them.

The example below only runs a single cycle of one Z stabilizer, so it can't pinpoint error precisely. However, by measuring the data qubits afterwards it's possible to guess at where the error(s) took place.

# Add measurements to the data qubits.
stabilizer_circuit_for_hardware = stabilizer_circuit + (
    cirq.Moment(cirq.measure(data_qubit, key=str(data_qubit)[-1]) for data_qubit in data_qubits)
)

Each result in the histogram below corresponds to a different set of possible errors. Below are some of the most likely cases for each measured result, or "syndrome", but there are many other possible cases not listed.

No flips (0_0000) could be no error, or two errors on the same qubit.
A single data flip (e.g. 0_1000) could be a post-CNOT data error, or a pre-CNOT data error and a measurement error.
A data flip and a measure flip (e.g. 1_1000) could be a pre-CNOT data error or post-CNOT errors on both flipped qubits.
Two data flips (e.g. 0_1100) could be pre-CNOT or post-CNOT errors on both flipped qubits.

...and so on, for more unusual cases.

As a final exercise on this circuit, it's possible to display a 2D heatmap of measurement results. This will show which qubits measured a \(|1\rangle\) most often; on a hardware device, this could be used to highlight the performance of specific qubits. See Heatmaps for more on visualizing error.

meas_map = {qubit_map[measure_qubit]: sum(results.measurements['meas']) / repetitions}

data_map = {
    qubit_map[dq]: sum(results.measurements[str(dq)[-1]]) / repetitions for dq in data_qubits
}

heatmap = cirq.Heatmap({**meas_map, **data_map})

Stabilizer measurements on a large grid

The next examples scale up the stabilizer grid to a 2x3 block of three Z stabilizers and three X stabilizers. Combining both stabilizer types allows many types of error to be detected and compensated for, although some ambiguity still remains. It also manually maps the circuit to the hardware qubits.

A real logical qubit would require many more stabilizers to be fault-tolerant; however, this toy example is already near the upper bound of what a full statevector simulator can simulate on personal-level computers.

# Consider the following grid, where numbers represent
# measure qubits and letters represent data qubits:
#
#     A
#    B0C

#     K5L

# X-plaquettes on [1, 2, 5]

[Optional] View 3D circuit

Large circuits that are mapped to grids are suitable to be visualized in 3D with cirq_web, if you find it useful, as follows:

!pip install --quiet cirq-web
import cirq_web

circuit_vis = cirq_web.Circuit3D(stabilizer_grid_circuit)
display(circuit_vis)

Without noise

The noiseless version of the larger grid is slightly more exciting than the small grid example: the X measure qubits will measure a random state since their neighbors are initialized in the Z basis. However, subsequent measurements will remain consistent.

The example below runs a single cycle of the 2x3 grid 100 times, then does a Z-basis measurement of all data qubits. Since each of these is a separate execution of the circuit, no correlation is expected between repetitions.

noiseless_sim = qsimcirq.QSimSimulator()

repetitions = 100
start = time.time()
results = noiseless_sim.run(stabilizer_grid_circuit, repetitions=repetitions)
elapsed = time.time() - start
print(f'{repetitions} repetitions completed in {elapsed:.03f}s')

100 repetitions completed in 0.010s

# Set to view results from each repetition.
repetition = 0  # @param {type:"number"}
meas_map = {
    qubit_map[q]: results.measurements[str(q)][repetition] for q in grid_meas_qubits.values()
}

data_map = {
    qubit_map[q]: results.measurements[str(q)][repetition] for q in grid_data_qubits.values()
}

heatmap = cirq.Heatmap({**meas_map, **data_map})
heatmap.plot()

With hardware noise on the QVM

Adding in hardware-like noise means that subsequent cycles of a stabilizer might disagree with one another. These inconsistencies can be interpreted as various error modes, which can be decoded to compensate for the errors observed.

Decoding stabilizer error is a complex topic not covered here, but the pre-decoding results and data qubit measurements shown below may shed some light on how to approach this process.
