Adaptable Continuous Variable Quantum Network with Finite Size Security
Runjia Zhang, Akash nag Oruganti, Huy Q. Nguyen +5
In recent years, continuous-variable quantum key distribution (CV-QKD) has become a promising paradigm for enabling secure communication among multiple end users sharing the same t…
Activating entanglement and EPR steering from continuous-variable resources using witness-based measures
Kaustav Chatterjee, Ulrik Lund Andersen
We introduce a general witness-based framework for quantifying and operationally activating continuous-variable (CV) resources into discrete-variable (DV) bipartite entanglement or…
Quantum State Characterization of Gravitational Waves via Graviton Counting Statistics
Kristian Toccacelo, Thomas Beitel, Ulrik Lund Andersen +1
Although gravitational waves are now routinely observed, the detection of individual gravitons has long been regarded as impossible. Recent work, however, has demonstrated that sin…
Quantum-enhanced biosensing enables earlier detection of bacterial growth
Rayssa B. de Andrade, Anne Egholm Høgh, Gaetana Spedalieri +4
Rapid detection of bacterial growth is crucial in clinical, food safety, and environmental contexts, yet conventional optical methods are limited by noise and require hours of incu…
Distribution of non-Gaussian states in a deployed telecommunication fiber channel
Casper A. Breum, Xueshi Guo, Mikkel V. Larsen +4
Optical non-Gaussian states hold great promise as a pivotal resource for advanced optical quantum information processing and fault-tolerant long-distance quantum communication. Est…
The loss tolerance of cat breeding for fault-tolerant grid state generation
Olga Solodovnikova, Ulrik L. Andersen, Jonas S. Neergaard-Nielsen
The development of a continuous-variable photonic quantum computer depends on the reliable preparation of high-quality Gottesman-Kitaev-Preskill states. The most promising GKP prep…
