High-Dimensional Quantum Photonics: Roadmap
Mehul Malik, Micheal Kues, Takuya Ikuta +30
The field of high-dimensional quantum photonics involves the use of multimode photonic degrees-of-freedom such as the spatial, temporal, or spectral structure of light to encode mu…
Detecting genuine multipartite entanglement in multi-qubit devices with restricted measurements
Nicky Kai Hong Li, Xi Dai, Manuel H. Muñoz-Arias +3
Detecting genuine multipartite entanglement (GME) is a state-characterization task that benchmarks coherence and experimental control in quantum systems. Existing GME tests often r…
Exploring Noisy Quantum Thermodynamical Processes via the Depolarizing-Channel Approximation
Jian Li, Xiaoyang Wang, Marcus Huber +2
Noise and errors are unavoidable in any realistic quantum process, including processes designed to reduce noise and errors in the first place. In particular, quantum thermodynamica…
Unknown measurement statistics cannot be redundantly copied using finite resources
Tiago Debarba, Marcus Huber, Nicolai Friis
Measurements can be viewed as interactions between a measured system and a pointer system that imprint information about the system on the pointer. For so-called unbiased interacti…
High-dimensional entanglement witnessed by correlations in arbitrary bases
Nicky Kai Hong Li, Marcus Huber, Nicolai Friis
Certifying entanglement is an important step in the development of many quantum technologies, especially for higher-dimensional systems, where entanglement promises increased capab…
Efficiently Cooling Quantum Systems with Finite Resources: Insights from Thermodynamic Geometry
Philip Taranto, Patryk Lipka-Bartosik, Nayeli A. RodrÃguez-Briones +4
Landauer's limit on heat dissipation during information erasure is critical as devices shrink, requiring optimal pure-state preparation to minimise errors. However, Nernst's third…
