Quantum Nondemolition Gate Operations and Measurements in Real Time on Fluctuating Signals
Yu Shiozawa, Jun-ichi Yoshikawa, Shota Yokoyama +10
We demonstrate an optical quantum nondemolition (QND) interaction gate with a bandwidth of about 100 MHz. Employing this gate, we are able to perform QND measurements in real time…
Heralded creation of photonic qudits from parametric down conversion using linear optics
Jun-ichi Yoshikawa, Marcel Bergmann, Peter van Loock +7
We propose an experimental scheme to generate, in a heralded fashion, arbitrary quantum superpositions of two-mode optical states with a fixed total photon number based on weak…
A hybrid quantum repeater for qudits
Marcel Bergmann, Peter van Loock
We present a "hybrid quantum repeater" protocol for the long-distance distribution of atomic entangled states beyond qubits. In our scheme, imperfect noisy entangled pairs of two q…
Teleportation-Assisted Optical CSIGN Gates
Fabian Ewert, Peter van Loock
Reliable entangling gates for qubits encoded in single-photon states represent a major challenge on the road to scalable quantum computing architectures based on linear optics. In…
Continuous-Variable Sampling from Photon-Added or Photon-Subtracted Squeezed States
Ulysse Chabaud, Tom Douce, Damian Markham +3
We introduce a new family of quantum circuits in Continuous Variables and we show that, relying on the widely accepted conjecture that the polynomial hierarchy of complexity classe…
