A proposal for a hybrid free-space optical quantum communication network with hexagonal boron nitride-based single photon sources
Julien Chénedé, Mostafa Abasifard, Tjorben Matthes +2
Hexagonal boron nitride (hBN) is known as a promising solid-state platform to host room temperature quantum emitters that produce high purity single photons. The bright and spectra…
QuaNTUM: A Modular Quantum Communication Testbed for Scalable Fiber and Satellite Integration
Julien Chénedé, Tjorben Matthes, Josefine Krause +2
Secure communication is essential for modern society, from financial transactions to critical infrastructure. As classical encryption faces threats from advancing computational pow…
Quantum Optics Applications of Hexagonal Boron Nitride Defects
Aslı Çakan, Chanaprom Cholsuk, Angus Gale +6
Hexagonal boron nitride (hBN) has emerged as a compelling platform for both classical and quantum technologies. In particular, the past decade has witnessed a surge of novel ideas…
The hBN defects database: a theoretical compilation of color centers in hexagonal boron nitride
Chanaprom Cholsuk, Ashkan Zand, Asli Cakan +1
Color centers in hexagonal boron nitride (hBN) have become an intensively researched system due to their potential applications in quantum technologies. There has been a large vari…
Identifying electronic transitions of defects in hexagonal boron nitride for quantum memories
Chanaprom Cholsuk, Asli Cakan, Sujin Suwanna +1
A quantum memory is a crucial keystone for enabling large-scale quantum networks. Applicable to the practical implementation, specific properties, i.e., long storage time, selectiv…
Rényi free energy and variational approximations to thermal states
Giacomo Giudice, Aslı Çakan, J. Ignacio Cirac +1
We propose the construction of thermodynamic ensembles that minimize the Rényi free energy, as an alternative to Gibbs states. For large systems, the local properties of these Rény…
Approximating the long time average of the density operator: Diagonal ensemble
Aslı Çakan, J. Ignacio Cirac, Mari Carmen Bañuls
For an isolated generic quantum system out of equilibrium, the long time average of observables is given by the diagonal ensemble, i.e. the mixed state with the same probability fo…
