Factoring 2048-bit RSA Integers in 177 Days with 13436 Qubits and a Multimode Memory

1 code implementation10 Mar 2021 Élie Gouzien, Nicolas Sangouard

Shorter run-times (and storage times) are achievable by increasing the number of qubits in the processing unit.

Setting up experimental Bell test with reinforcement learning

no code implementations4 May 2020 Alexey A. Melnikov, Pavel Sekatski, Nicolas Sangouard

Finding optical setups producing measurement results with a targeted probability distribution is hard as a priori the number of possible experimental implementations grows exponentially with the number of modes and the number of devices.


Experimental many-pairs nonlocality

1 code implementation4 Apr 2017 Hou Shun Poh, Alessandro Cerè, Jean-Daniel Bancal, Yu Cai, Nicolas Sangouard, Valerio Scarani, Christian Kurtsiefer

Collective measurements on large quantum systems together with a majority voting strategy can lead to a violation of the CHSH Bell inequality.

Proposal for Implementing Device-Independent Quantum Key Distribution based on a Heralded Qubit Amplification

no code implementations2 Mar 2010 Nicolas Gisin, Stefano Pironio, Nicolas Sangouard

In device-independent quantum key distribution (DIQKD), the violation of a Bell inequality is exploited to establish a shared key that is secure independently of the internal workings of the QKD devices.

Quantum repeaters based on atomic ensembles and linear optics

no code implementations15 Jun 2009 Nicolas Sangouard, Christoph Simon, Hugues de Riedmatten, Nicolas Gisin

Such protocols require the capacity to create entanglement in a heralded fashion, to store it in quantum memories, and to swap it.
