Efficient and Robust Quantum Key Distribution With Minimal State Tomography
Berthold-Georg Englert, Dagomir Kaszlikowski, Hui Khoon Ng +3
We introduce the Singapore protocol, a qubit protocol for quantum key distribution that is fully tomographic, more efficient than other tomographic protocols, and very robust. Unde…
Single-loop interferometer for minimal ellipsometry
Berthold-Georg Englert, Tin Kah Ming, Goh Choon Guan +1
We present a simple polarizing Mach-Zehnder interferometer that can be used for optimal minimal ellipsometry: Only four intensities are measured to determine the three Stokes param…
Iterative procedure for computing accessible information in quantum communication
Jaroslav Řeháček, Berthold-Georg Englert, Dagomir Kaszlikowski
We present an iterative algorithm that finds the optimal measurement for extracting the accessible information in any quantum communication scenario. The maximization is achieved b…
Violation of Bell's inequality for continuous variables
L. Praxmeyer, B. -G. Englert, K. Wodkiewicz
We construct a wide class of bounded continuous variables observables that lead to violations of Bell inequalities for the EPR state and give an intuitive Wigner function explanati…
Minimal qubit tomography
Jaroslav Řeháček, Berthold-Georg Englert, Dagomir Kaszlikowski
We present, and analyze thoroughly, a highly symmetric and efficient scheme for the determination of a single-qubit state, such as the polarization properties of photons emitted by…
