Estimating the precision for quantum process tomography
E. O. Kiktenko, D. N. Kublikova, A. K. Fedorov
Quantum tomography is a widely applicable tool for complete characterization of quantum states and processes. In the present work, we develop a method for precision-guaranteed quan…
Efficient generation of temporally shaped photons using nonlocal spectral filtering
Valentin Averchenko, Denis Sych, Christoph Marquardt +1
We study the generation of single-photon pulses with the tailored temporal shape via nonlocal spectral filtering. A shaped photon is heralded from a time-energy entangled photon pa…
Quantum interference test of the equivalence principle on antihydrogen
P. -P. Crépin, C. Christen, R. Guérout +3
We propose to use quantum interferences to improve the accuracy of the measurement of the free fall acceleration g of antihydrogen in the GBAR experiment. This method uses most ant…
Eavesdropper's ability to attack a free-space quantum-key-distribution receiver in atmospheric turbulence
Poompong Chaiwongkhot, Katanya B. Kuntz, Yanbao Zhang +6
The ability of an eavesdropper (Eve) to perform an intercept-resend attack on a free-space quantum key distribution (QKD) receiver by precisely controlling the incidence angle of a…
