Entanglement between a diamond spin qubit and a photonic time-bin qubit at telecom wavelength
Anna Tchebotareva, Sophie L. N. Hermans, Peter C. Humphreys +8
We report on the realization and verification of quantum entanglement between an NV electron spin qubit and a telecom-band photonic qubit. First we generate entanglement between th…
Maximally Entangled Mixed-State Generation via Local Operations
A. Aiello, G. Puentes, D. Voigt +1
We present a general theoretical method to generate maximally entangled mixed states of a pair of photons initially prepared in the singlet polarization state. This method requires…
Efficient coherent internal state transfer in trapped ions using Stimulated Raman Adiabatic Passage
Jens L. Sørensen, Ditte Møller, Theis Iversen +5
We demonstrate experimentally how the process of Stimulated Raman Adiabatic Passage (STIRAP) can be utilized for efficient coherent internal state transfer in single trapped and la…
Entangled mixed-state generation by twin-photon scattering
G. Puentes, D. Voigt, A. Aiello +1
We report experimental results on mixed-state generation by multiple scattering of polarization-entangled photon pairs created from parametric down-conversion. By using a large var…
Maximally entangled mixed states made easy
A. Aiello, G. Puentes, D. Voigt +1
We show that it is possible to achieve maximally entangled mixed states of two qubits from the singlet state via the action of local non-trace-preserving quantum channels. Moreover…
Maximum-likelihood estimation prevents unphysical Mueller matrices
A. Aiello, G. Puentes, D. Voigt +1
We show that the method of maximum-likelihood estimation, recently introduced in the context of quantum process tomography, can be applied to the determination of Mueller matrices…
