Realization of a photonic CNOT gate sufficient for quantum computation
Sara Gasparoni, Jian-Wei Pan, Philip Walther +2
We report the first experimental demonstration of a quantum controlled-NOT gate for different photons, which is classically feed-forwardable. In the experiment, we achieved this go…

De Broglie Wavelength of a Nonlocal Four-Photon
Philip Walther, Jian-Wei Pan, Markus Aspelmeyer +3
Superposition is one of the most distinct features of quantum theory and has been demonstrated in numerous realizations of Young's classical double-slit interference experiment and…
