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…
Fast simulations of continuous-variable circuits using the coherent state decomposition
Olga Solodovnikova, Ulrik L. Andersen, Jonas S. Neergaard-Nielsen
We present \texttt{lcg\_plus}, an open-source Python library for the simulation of continuous-variable quantum circuits with both generaldyne and photon-number-resolving detector c…
General Approach to Error Detection of Bosonic Codes via Phase Estimation
Yuan-De Jin, Shi-Yu Zhang, Ulrik L. Andersen +1
We present a general approach to error detection of bosonic quantum error-correction codes via an adaptive quantum phase estimation algorithm assisted by a single ancilla qubit. Th…
Performance analysis of GKP error correction
Frederik K. Marqversen, Janus H. Wesenberg, Nikolaj T. Zinner +1
Quantum error correction is essential for achieving fault-tolerant quantum computing. Gottesman-Kitaev-Preskill (GKP) codes are particularly effective at correcting continuous nois…
