Thermal Entanglement and Out-of-Equilibrium Thermodynamics in 1D Bose gases
Julia Mathé, Nicky Kai Hong Li, Pharnam Bakhshinezhad +1
We investigate entanglement in and out of equilibrium in a one-dimensional Bose gas in its low-energy Bogoliubov regime. In this Gaussian setting, the state is fully characterized…
High-dimensional quantum communication with scalable photonic entanglement in time and frequency
Kai-Chi Chang, Murat Can Sarihan, Nicky Kai Hong Li +13
High-dimensional photonic entanglement holds significant promise for advancing quantum communication, computation, and metrology. For example, large-alphabet quantum communication…
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…
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…
Experimental high-dimensional entanglement certification and quantum steering with time-energy measurements
Kai-Chi Chang, Murat Can Sarihan, Paul Erker +8
High-dimensional entanglement provides unique ways of transcending the limitations of current approaches in quantum information processing, quantum communications based on qubits.…
Identifying families of multipartite states with non-trivial local entanglement transformations
Nicky Kai Hong Li, Cornelia Spee, Martin Hebenstreit +2
The study of state transformations by spatially separated parties with local operations assisted by classical communication (LOCC) plays a crucial role in entanglement theory and i…
State transformations within entanglement classes containing permutation-symmetric states
Martin Hebenstreit, Cornelia Spee, Nicky Kai Hong Li +2
The study of state transformations under local operations and classical communication (LOCC) plays a crucial role in entanglement theory. While this has been long ago characterized…
Improving key rates of the unbalanced phase-encoded BB84 protocol using the flag-state squashing model
Nicky Kai Hong Li, Norbert Lütkenhaus
All phase-encoded BB84 implementations have signal states with unbalanced amplitudes in practice. Thus, the original security analyses a priori do not apply to them. Previous secur…
