Qutrit entanglement and joint multi-parameter estimation in an optical clock platform
Ohad Lib, Shuheng Liu, Maximilian Ammenwerth +7
Quantum metrology harnesses entanglement to improve measurement precision beyond classical limits. While standard protocols rely on two-level qubits to estimate a single parameter,…
Genuine Hybrid Number-Polarization Entanglement
Dorian Schiffer, Marcus Huber, Elizabeth Agudelo
Entanglement is a key resource for fundamental tests of physics and emerging quantum technologies. In quantum optics, two perspectives on entanglement coexist. In the continuous-va…
Characterizing high-dimensional multipartite entanglement beyond Greenberger-Horne-Zeilinger fidelities
Shuheng Liu, Qiongyi He, Marcus Huber +1
Characterizing entanglement of systems composed of multiple particles is a very complex problem that is attracting increasing attention across different disciplines related to quan…
Entanglement Dimensionality of Continuous Variable States From Phase-Space Quasi-Probabilities
Shuheng Liu, Jiajie Guo, Matteo Fadel +3
The dimensionality of entanglement is a core tenet of quantum information processing, especially quantum communication and computation. While it is natural to think of this dimensi…
Observation of Genuine High-dimensional Multi-partite Non-locality in Entangled Photon States
Xiao-Min Hu, Cen-Xiao Huang, Nicola d'Alessandro +10
Quantum information science has leaped forward with the exploration of high-dimensional quantum systems, offering greater potential than traditional qubits in quantum communication…
Experimental certification of high-dimensional entanglement with randomized measurements
Ohad Lib, Shuheng Liu, Ronen Shekel +4
High-dimensional entangled states offer higher information capacity and stronger resilience to noise compared with two-dimensional systems. However, the large number of modes and s…
