A quantum Fredkin gate
Raj B. Patel, Joseph Ho, Franck Ferreyrol +2
Key to realising quantum computers is minimising the resources required to build logic gates into useful processing circuits. While the salient features of a quantum computer have…
Qubit-Programmable Operations on Quantum Light Fields
Marco Barbieri, Nicolò Spagnolo, Franck Ferreyrol +3
Engineering quantum operations is one of the main abilities we need for developing quantum technologies and designing new fundamental tests. Here we propose a scheme for realising…
Heralded processes on continuous-variable spaces as quantum maps
Franck Ferreyrol, Nicolò Spagnolo, Rémi Blandino +2
Conditional evolution is crucial for generating non-Gaussian resources for quantum information tasks in the continuous variable scenario. However, tools are lacking for a convenien…
A method for characterizing coherent-state quantum gates
Rémi Blandino, Franck Ferreyrol, Marco Barbieri +2
We discuss and implement experimentally a method for characterizing quantum gates operating on superpositions of coherent states. The peculiarity of this encoding of qubits is to w…
Non-Gaussianity of quantum states: an experimental test on single-photon added coherent states
Marco Barbieri, Nicolò Spagnolo, Marco G. Genoni +5
Non Gaussian states and processes are useful resources in quantum information with continuous variables. An experimentally accessible criterion has been proposed to measure the deg…
Implementation of a non-deterministic optical noiseless amplifier
Franck Ferreyrol, Marco Barbieri, Remi Blandino +3
Quantum mechanics imposes that any amplifier that works independently on the phase of the input signal has to introduce some excess noise. The impossibility of such a noiseless amp…
