Enhanced production of HD and D_2 molecules on small dust grains in diffuse clouds
Azi Lipshtat, Ofer Biham, Eric Herbst
Motivated by recent observations of deuterated molecules in the interstellar medium, we examine the production of HD and D molecules on dust grain surfaces. A mechanism for the…
One dimensional quantum walk with unitary noise
Daniel Shapira, Ofer Biham, A. J. Bracken +1
The effect of unitary noise on the discrete one-dimensional quantum walk is studied using computer simulations. For the noiseless quantum walk, starting at the origin (n=0) at time…
Characterization of pure quantum states of multiple qubits using the Groverian entanglement measure
Yishai Shimoni, Daniel Shapira, Ofer Biham
The Groverian entanglement measure, G(psi), is applied to characterize a variety of pure quantum states |psi> of multiple qubits. The Groverian measure is calculated analytically f…
The effect of unitary noise on Grover's quantum search algorithm
D. Shapira, S. Mozes, O. Biham
The effect of unitary noise on the performance of Grover's quantum search algorithm is studied. This type of noise may result from tiny fluctuations and drift in the parameters of…
Analysis of Grover's quantum search algorithm as a dynamical system
O. Biham, D. Shapira, Y. Shimoni
Grover's quantum search algorithm is analyzed for the case in which the initial state is an arbitrary pure quantum state of qubits. It is shown that the optimal time to p…
Sandpile models and random walkers on finite lattices
Yehiel Shilo, Ofer Biham
Abelian sandpile models, both deterministic, such as the Bak, Tang, Wiesenfeld (BTW) model [P. Bak, C. Tang and K. Wiesenfeld, Phys. Rev. Lett. {\bf 59}, 381 (1987)], and stochasti…
