Photoionization accompanied by excitation at intermediate photon energies
E. G. Drukarev, E. Z. Liverts, M. Ya. Amusia +2
We calculate the photoionization with excitation-to photoionization ratios for atomic helium and heliumlike ions at intermediate values of the photon energies. The final state inte…
Simple and secure quantum key distribution with biphotons
I. Bregman, D. Aharonov, M. Ben-Or +1
The best qubit one-way quantum key distribution (QKD) protocol can tolerate up to 14.1% in the error rate. It has been shown how this rate can be increased by using larger quantum…
Formation of Multipartite Entanglement Using Random Quantum Gates
Yonatan Most, Yishai Shimoni, Ofer Biham
The formation of multipartite quantum entanglement by repeated operation of one and two qubit gates is examined. The resulting entanglement is evaluated using two measures: the ave…
The dynamical hole in ultrafast photoassociation: analysis of the compression effect
Eliane Luc-Koenig, Françoise Masnou-Seeuws, Ronnie Kosloff
Photoassociation of a pair of cooled atoms by excitation with a short chirped laser pulse creates a dynamical hole in the initial continuum wavefunction. This hole is manifested by…
The power of quantum systems on a line
Dorit Aharonov, Daniel Gottesman, Sandy Irani +1
We study the computational strength of quantum particles (each of finite dimensionality) arranged on a line. First, we prove that it is possible to perform universal adiabatic quan…
Quantic Superpositions and the Geometry of Complex Hilbert Spaces
Daniel Lehmann
The concept of a superposition is a revolutionary novelty introduced by Quantum Mechanics. If a system may be in any one of two pure states x and y, we must consider that it may al…
