Stability of Exponential Tails in the Scattering on Wedges and Impurities
Yakir Aharonov, Pawel O. Mazur
We study a simple exactly solvable 2D model describing the interaction of a localized particle with an impurity. The localization potential causes the particle to be…
Approximate quantum error correction for correlated noise
Avraham Ben-Aroya, Amnon Ta-Shma
Most of the research done on quantum error correction studies an error model in which each qubit is affected by noise, independently of the other qubits. In this paper we study a d…
Some Aspects of Classical and Quantum Phases
Yakir Aharonov, Tirzah Kaufherr, Shmuel Nussinov
We study classical and quantum phases in the adiabatic Born-Oppenheimer context. These include a classical astronomical case, the general dual description of the phases, a new "Par…
On the complexity of approximating the diamond norm
Avraham Ben-Aroya, Amnon Ta-Shma
The diamond norm is a norm defined over the space of quantum transformations. This norm has a natural operational interpretation: it measures how well one can distinguish between t…
