Maximal p-norms of entanglement breaking channels
C. King
It shown that when one of the components of a product channel is entanglement breaking, the output state with maximal p-norm is always a product state. This result complements Shor…
Exponential algorithmic speedup by quantum walk
Andrew M. Childs, Richard Cleve, Enrico Deotto +3
We construct an oracular (i.e., black box) problem that can be solved exponentially faster on a quantum computer than on a classical computer. The quantum algorithm is based on a c…
Coherent back-scattering near the two-dimensional metal-insulator transition
Maryam Rahimi, S. Anissimova, M. R. Sakr +2
We have studied corrections to conductivity due to the coherent backscattering in low-disordered two-dimensional electron systems in silicon for a range of electron densities inclu…
Fractal Weyl laws for chaotic open systems
W. T. Lu, S. Sridhar, Maciej Zworski
We present a result relating the density of quantum resonances for an open chaotic system to the fractal dimension of the associated classical repeller. The result is supported by…
Sinai billiards, Ruelle zeta-functions and Ruelle resonances: microwave experiments
S. Sridhar, W. T. Lu
We discuss the impact of recent developments in the theory of chaotic dynamical systems, particularly the results of Sinai and Ruelle, on microwave experiments designed to study qu…
Compressibility of a two-dimensional hole gas in tilted magnetic field
Maryam Rahimi, M. R. Sakr, S. V. Kravchenko +2
We have measured compressibility of a two-dimensional hole gas in p-GaAs/AlGaAs heterostructure, grown on a (100) surface, in the presence of a tilted magnetic field. It turns out…
