IBM Q - Individual Run Results

Question

In Qiskit, is there a way to get the individual results from each shot on the IBM quantum device (instead of simply the summary statistics)? The result JSON file provides the count of all the 1024 shots.

You can set memory=True in assemble() or execute(). Then use result.get_memory() to get the per-shot measurement.
For example:
job = execute(circs, memory=True, shots=4)
result = job.result()
print(result.get_counts(0))  # prints {'00': 3, '11': 1}
print(result.get_memory(0))  # prints ['00', '00', '11', '00']

It seems like this documentation will help you: https://qiskit.org/documentation/stubs/qiskit.result.Result.html#qiskit.result.Result.get_memory
from qiskit import QuantumCircuit, Aer, execute
provider = IBMQ.load_account()

circuit = QuantumCircuit(3)

circuit.h(0)
circuit.h(1)
circuit.cx(0, 1)
circuit.cx(0, 2)
circuit.barrier(range(3))
circuit.h(0)
circuit.h(1)
circuit.barrier(range(3))
circuit.measure_all()
print(circuit)

job = execute(circuit, Aer.get_backend('qasm_simulator'), shots=10, memory=True)

print('result for each shot:', job.result().get_memory() )
