Experimental demonstration of Continuous-Variable Quantum Key Distribution with a silicon photonics integrated receiver
Yoann Piétri, Luis Trigo Vidarte, Matteo Schiavon +4
Quantum Key Distribution (QKD) is a prominent application in the field of quantum cryptography providing information-theoretic security for secret key exchange. The implementation…
Revisiting Quantum Contextuality in an Algebraic Framework
Mathias Van Den Bossche, Philippe Grangier
Within the framework of quantum contextuality, we discuss the ideas of extracontextuality and extravalence, that allow one to relate Kochen-Specker's and Gleason's theorems. We emp…
A contextually objective approach to the extended Wigner's friend thought experiment
Maxime Federico, Philippe Grangier
We present a discussion of the extended Wigner's friend thought experiment proposed by Frauchiger and Renner in [1]. We show by using various arguments, including textbook quantum…
Why is incomplete indeed: a simple illustration
Philippe Grangier
With the Nobel Prize attributed to Aspect, Clauser, and Zeilinger, the international scientific community acknowledged the fundamental importance of the experimental violation of B…
Long-Range QKD without Trusted Nodes is Not Possible with Current Technology
Bruno Huttner, Romain Alléaume, Eleni Diamanti +11
A recently published patent (https://www.ipo.gov.uk/p-ipsum/Case/PublicationNumber/GB2590064) has claimed the development of a novel quantum key distribution protocol purporting to…
Contextual unification of classical and quantum physics
Mathias Van Den Bossche, Philippe Grangier
Following an article by John von Neumann on infinite tensor products, we develop the idea that the usual formalism of quantum mechanics, associated with unitary equivalence of repr…
Experimental Demonstration of Discrete Modulation Formats for Continuous Variable Quantum Key Distribution
François Roumestan, Amirhossein Ghazisaeidi, Jérémie Renaudier +4
Quantum key distribution (QKD) enables the establishment of secret keys between users connected via a channel vulnerable to eavesdropping, with information-theoretic security, that…
Revisiting Quantum Contextuality
Philippe Grangier
The purpose of this note is to complete the interesting review on quantum contextuality [1] that appeared recently. In particular we will introduce and discuss the ideas of extraco…
High-Rate Continuous Variable Quantum Key Distribution Based on Probabilistically Shaped 64 and 256-QAM
François Roumestan, Amirhossein Ghazisaeidi, Jérémie Renaudier +3
We designed a CV-QKD system with off-the-shelf components and established the feasibility of distributing 67.6 and 66.8 Mb/s secret key rates on average over a 9.5 km SMF link, usi…
Demonstration of Probabilistic Constellation Shaping for Continuous Variable Quantum Key Distribution
François Roumestan, Amirhossein Ghazisaeidi, Jérémie Renaudier +3
We demonstrate, for the first time to our knowledge, continuous-variable quantum key distribution using probabilistically-shaped 1024-QAM and true local oscillator, achieving 38.3M…
Revisiting Born's rule through Uhlhorn's and Gleason's theorems
Alexia Auffeves, Philippe Grangier
In a previous article [1] we presented an argument to obtain (or rather infer) Born's rule, based on a simple set of axioms named "Contexts, Systems and Modalities" (CSM). In this…
Revisiting Quantum Mysteries
Philippe Grangier
In this article we argue that in quantum mechanics, and in opposition to classical physics, it is impossible to say that an isolated quantum system "owns" a physical property. Some…
Contextual inferences, nonlocality, and the incompleteness of quantum mechanics
Philippe Grangier
It is known that "quantum non locality", leading to the violation of Bell's inequality and more generally of classical local realism, can be attributed to the conjunction of two pr…
Production and applications of non-Gaussian quantum states of light
A. I. Lvovsky, Philippe Grangier, Alexei Ourjoumtsev +3
This review covers recent theoretical and experimental efforts to extend the application of the continuous-variable quantum technology of light beyond "Gaussian" quantum states, su…
Completing the quantum formalism in a contextually objective framework
Philippe Grangier
In standard quantum mechanics (QM), a state vector may belong to infinitely many different orthogonal bases, as soon as the dimension of the Hilbert space is at le…
Deriving Born's rule from an Inference to the Best Explanation
Alexia Auffeves, Philippe Grangier
In previous articles we presented a simple set of axioms named Contexts, Systems and Modalities (CSM), where the structure of quantum mechanics appears as a result of the interplay…
A generic model for quantum measurements
Alexia Auffèves, Philippe Grangier
In previous articles we presented a derivation of Born's rule and unitary transforms in Quantum Mechanics (QM), from a simple set of axioms built upon a physical phenomenology of q…
Comment on "The photon identification loophole in EPRB experiments: computer models with single-wing selection"
Mateus Araújo, Philippe Grangier, Jan-Åke Larsson
Contrary to the claims made in Ref. [1], the recent Bell tests by Giustina et al. and Shalm et al. do not suffer from a "photon identification loophole". The model discussed in Ref…
What is quantum in quantum randomness?
Philippe Grangier, Alexia Auffèves
It is often said that quantum and classical randomness are of different nature, the former being ontological and the latter epistemological. However, so far the question of "What i…
Diagrammatic treatment of few-photon scattering from a Rydberg blockaded atomic ensemble in a cavity
A. Grankin, P. Grangier, E. Brion
In a previous letter we studied the giant optical nonlinearities of a Rydberg atomic medium within an optical cavity, in the Schwinger-Keldysh formalism. In particular, we calculat…
Extracontextuality and Extravalence in Quantum Mechanics
Alexia Auffèves, Philippe Grangier
We develop the point of view where Quantum Mechanics results from the interplay between the quantized number of "modalities" accessible to a quantum system, and the continuum of "c…
Recovering the quantum formalism from physically realist axioms
Alexia Auffeves, Philippe Grangier
We present a heuristic derivation of Born's rule and unitary transforms in Quantum Mechanics, from a simple set of axioms built upon a physical phenomenology of quantization. This…
Violation of Bell's inequalities in a quantum realistic framework
Alexia Auffèves, Philippe Grangier
We discuss the recently observed "loophole free" violation of Bell's inequalities in the framework of a physically realist view of quantum mechanics, which requires that physical p…
Loss-tolerant quantum enhanced metrology and state engineering via the reverse Hong-Ou-Mandel effect
Alexander E. Ulanov, Ilya A. Fedorov, Demid Sychev +2
Preparing highly entangled quantum states between remote parties is a major challenge for quantum communications [1-8]. Particularly promising in this context are the N00N states,…
