Knowledge and ignorance in incomplete quantum state tomography
Y. S. Teo, H. Zhu, B. -G. Englert +2
Quantum state reconstruction on a finite number of copies of a quantum system with informationally incomplete measurements does, as a rule, not yield a unique result. We derive a r…

Demonstration of reversible phase-insensitive optical amplifier
Jun-ichi Yoshikawa, Yoshichika Miwa, Radim Filip +1
We experimentally demonstrate phase-insensitive linear optical amplification which preserves the idler at the output. Since our amplification operation is unitary up to small exces…
