View on GitHub

Open this notebook in GitHub to run it yourself

The bitwise inversion operation receives a quantum register representing some number

x

, and inverts its binary representation, namely, replaces

1

s by

0

s and vice versa.

def main(x: Output[QNum], y: Output[QNum]) -> None:
    x |= 6

    y |= ~x

qprog = synthesize(main)

result = sample(qprog)
print(result)
