Exploring a new regime for processing optical qubits: squeezing and unsqueezing single photons
Yoshichika Miwa, Jun-ichi Yoshikawa, Noriaki Iwata +5
We implement the squeezing operation as a genuine quantum gate, deterministically and reversibly acting `online' upon an input state no longer restricted to the set of Gaussian sta…
Parallel generation of quadripartite cluster entanglement in the optical frequency comb
Matthew Pysher, Yoshichika Miwa, Reihaneh Shahrokhshahi +2
Scalability and coherence are two essential requirements for the experimental implementation of quantum information and quantum computing. Here, we report a breakthrough toward sca…
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…
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…
Demonstration of a universal one-way quantum quadratic phase gate
Yoshichika Miwa, Jun-ichi Yoshikawa, Peter van Loock +1
We demonstrate a quadratic phase gate for one-way quantum computation in the continuous-variable regime. This canonical gate, together with phase-space displacements and Fourier ro…
