Hi, what do you mean by increasing the error-rate? Are you using the noisy IBM simulator?
I'm using the Alice&Bob Qiskit provider (https://github.com/Alice-Bob-SW/qiskit-alice-bob-provider). It is based on the IBM noisy simulator, where we apply the noise model for each gate.
A possible problem might be that the simulation runs out of memory and crashes the server (which results in a connection reset). Could you modify the following code such that it directly runs qiskit_qc on your backend and see if it crashes.
def get_r_candidates(approx):
rationals = continued_fraction_convergents(continued_fraction_iterator(Rational(approx)))
return [rat.q for rat in rationals]
def find_order(a, N):
qg = QuantumModulus(N)
qg[:] = 1
qpe_res = QuantumFloat(2*qg.size + 1, exponent = -(2*qg.size + 1))
h(qpe_res)
x=a
for i in range(len(qpe_res)):
with control(qpe_res[i]):
qg *= x
x = (x*x)%N
QFT(qpe_res, inv = True)
qiskit_qc = qpe_res.qs.compile().to_qiskit()
# run qiskit_qc with your backend here and see if it crashes.
return qpe_res.get_measurement(backend=vrtl_qasm_sim)
def quantum_shor(a,N):
meas_res = find_order(a,N)
r_candidates = sum([get_r_candidates(approx) for approx in meas_res.keys()], [])
for cand in r_candidates:
if (a**cand)%N == 1:
r = cand
break
else:
raise Exception("Please sample again")
if r % 2:
raise Exception("Please choose another a")
p = np.gcd(a**(r//2)+1, N)
q = int(N/p)
if(p>q):
return(q,p)
return(p,q)
for _ in range(10):
print(quantum_shor(a,N))
In any case, we will need to adjust the error message, so thank you for your report :)
I'm getting disconnected when I try to run jobs for a longer time than what I usually do. Could somebody tell me where does the problem come from and if there is already a solution for that, apart from exporting the circuit into QASM and run it independently from Qrisp?
The issue is generated by multiple runs of the following code:
