Reversing Quantum Nondemolition Interaction as Quantum Erasing
Yoshichika Miwa, Jun-ichi Yoshikawa, Ryuji Ukai +2
We reverse a quantum nondemolition (QND) interaction and restore the signal quantum state by measurement and feedforward. This operation corresponds to quantum erasing for continuo…

Demonstration of Cluster State Shaping and Quantum Erasure for Continuous Variables
Yoshichika Miwa, Ryuji Ukai, Jun-ichi Yoshikawa +3
We demonstrate experimentally how to remove an arbitrary node from a continuous-variable cluster state and how to shorten any quantum wires of such a state. These two basic operati…
