Crossed crystal scheme for fs-pulsed entangled photon generation in ppKTP
Thomas Scheidl, Felix Tiefenbacher, Robert Prevedel +3
We demonstrate a novel scheme for femto-second pulsed spontaneous parametric down-conversion in periodically poled KTP crystals. Our scheme is based on a crossed crystal configurat…
Quantum computing on encrypted data
K. Fisher, A. Broadbent, L. K. Shalm +5
The ability to perform computations on encrypted data is a powerful tool for protecting privacy. Recently, protocols to achieve this on classical computing systems have been found.…
Experimental Three-Particle Quantum Nonlocality under Strict Locality Conditions
C. Erven, E. Meyer-Scott, K. Fisher +13
Quantum correlations are critical to our understanding of nature, with far-reaching technological and fundamental impact. These often manifest as violations of Bell's inequalities,…
Optimal linear optical implementation of a single-qubit damping channel
Kent Fisher, Robert Prevedel, Rainer Kaltenbaek +1
We experimentally demonstrate a single-qubit decohering quantum channel using linear optics. We implement the channel, whose special cases include both the amplitude-damping channe…
Efficient quantum computing using coherent photon conversion
N. K. Langford, S. Ramelow, R. Prevedel +3
Single photons provide excellent quantum information carriers, but current schemes for preparing, processing and measuring them are inefficient. For example, down-conversion provid…
Classical analog for dispersion cancellation of entangled photons with local detection
R. Prevedel, K. M. Schreiter, J. Lavoie +1
Energy-time entangled photon pairs remain tightly correlated in time when the photons are passed through equal magnitude, but opposite in sign, dispersion. A recent experimental de…
