Our paper on testing non-Gaussian character of Schroedinger’s cat state produced under realistic conditions has been published in Physical Review A [10.1103/PhysRevA.86.043813]. In collaboration with QUIN group of prof. Ulrik Andersen we have experimentally verified the quantum non-Gaussian character of
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
