Locally observable conditions for the successful implementation of entangling multi-qubit quantum gates
Holger F. Hofmann, Ryo Okamoto, Shigeki Takeuchi
The information obtained from the operation of a quantum gate on only two complementary sets of input states is sufficient to estimate the quantum process fidelity of the gate. In…

Demonstration of an optical quantum controlled-NOT gate without path interference
Ryo Okamoto, Holger F. Hofmann, Shigeki Takeuchi +1
We report the first experimental demonstration of an optical quantum controlled-NOT gate without any path interference, where the two interacting path interferometers of the origin…
