Hadamard gate for coherent state qubits

Our paper on Hadamard gate for coherent state qubits (Schroedinger cat-like states) has been published in Physical Review A as Rapid Communication [Phys. Rev. A 84, 050301(R) (2011)]. The project was done in cooperation of prof. Ulrik L. Andersen’s group

Hadamard gate for coherent state qubits

We have experimentally demonstrated a single mode Hadamard gate for coherent state qubits by using a hybrid projector system consisting of a conditional homodyne detector and a photon counter. This implementation constitutes the first step towards the demonstration of quantum
