Experimental probe of quantum coherence in top-quark pair production at the LHC
Saeed Haddadi, Majid Azizi, Artur Czerwinski +1
We investigate quantum coherence in the spin degrees of freedom of top--antitop pairs produced at the LHC using the -norm of coherence in the helicity basis. Combining Standar…
Single-photon emission modeling with statistical estimators for the exponential distribution
Artur Czerwinski, Katarzyna Czerwinska, Xiangji Cai +5
Single-photon sources are used in numerous quantum technologies, from sensing and imaging to communication, making the accurate modeling of their emissions essential. In this work,…
Quantum speed limits in dephasing dynamics of a qubit system coupled to thermal environments
Xiangji Cai, Yanyan Feng, Jing Ren +4
We theoretically study the quantum speed limits (QSLs) of a qubit system coupled to a thermal dephasing environment with an Ohmic-like spectral density. Based on the geometric QSLs…
Optimizing Continuous-Wave-Pumped Entanglement-based QKD in Noisy Environments
