Randomized benchmarking for 1-qubit and 2-qubit

Install

pip install rb_generator

Usage

See test.

rb22.get_full_sequence_and_inverse_sequence

rb22 = rb_generator.RB22()

# Open file first
if not rb22.load_from_file('./rb22.dat'):
    print('load failed')
    exit(0)

# Define the clifford length
clifford_length = 100

# Generate a random sequence (each element in [0, N-1], N is the size of the clifford group)
cliffords = np.random.randint(0, rb22.N, clifford_length)
sequence, inverse_sequence = rb22.get_full_sequence_and_inverse_sequence(cliffords)

print(sequence)
print(inverse_sequence)
# You will obtain the following two outputs

# sequence = [3, 6, 5, 4, 1, 4, 4, 5, 2, 5, 3, 4, 3, 3, 6, 5, 6, 5, 4, 5, 1, 6, 3, 4, 5, 4, 4, 3, 5, 4, 3, 4, 5, 4, 6, 2, 3, 3, 4, 1, 4, 6, 5, 3, 3, 6, 3, 1, 6, 3, 6, 6, 5, 4, 3, 3, 4, 5, 4, 5, 5, 6, 4, 5, 0, 6, 5, 2, 5, 5, 4, 3, 6, 5, 2, 3, 5, 3, 6, 3, 4, 3, 4, 5, 3, 6, 6, 5, 3, 4, 5, 4, 3, 0, 3, 4, 3, 4, 2, 3, 2, 5, 1, 6, 4, 5, 6, 5, 3, 3, 6, 3, 5, 6, 5, 4, 5, 4, 3, 6, 3, 6, 5, 5, 4, 4, 5, 2, 2, 2, 1, 6, 6, 2, 3, 4, 3, 4, 5, 6, 6, 3, 6, 3, 4, 1, 4, 3, 6, 3, 0, 6, 5, 4, 5, 6, 3, 3, 4, 3, 4, 5, 6, 5, 6, 3, 2, 3, 6, 3, 0, 1, 6, 5, 6, 2, 3, 5, 4, 5, 6, 5, 6, 5]

# inverse_sequence = [5, 6]

"sequence" means the operation sequence for generating the RB sequence. "inverse_sequence" means the operation sequence for inverting the sequence to identity.

rb44.get_full_sequence_and_inverse_sequence

Same as the version of rb22.
