An Inflationary Fixed Point Operator in XQuery
Loredana Afanasiev, Torsten Grust, Maarten Marx +2
We introduce a controlled form of recursion in XQuery, inflationary fixed points, familiar in the context of relational databases. This imposes restrictions on the expressible type…
Cryptography from Noisy Storage
Stephanie Wehner, Christian Schaffner, Barbara Terhal
We show how to implement cryptographic primitives based on the realistic assumption that quantum storage of qubits is noisy. We thereby consider individual-storage attacks, i.e. th…
The role of spin noise in the detection of nanoscale ensembles of nuclear spins
C. L. Degen, M. Poggio, H. J. Mamin +1
When probing nuclear spins in materials on the nanometer scale, random fluctuations of the spin polarization will exceed the mean Boltzmann polarization for sample volumes below ab…
Distributed source coding in dense sensor networks
Akshay Kashyap, Luis Alfonso Lastras-Montaño, Cathy Xia +1
We study the problem of the reconstruction of a Gaussian field defined in [0,1] using N sensors deployed at regular intervals. The goal is to quantify the total data rate required…
Chaotic Period Doubling
V. V. M. S. Chandramouli, M. Martens, W. de Melo +1
The period doubling renormalization operator was introduced by M. Feigenbaum and by P. Coullet and C. Tresser in the nineteen-seventieth to study the asymptotic small scale geometr…
Efficient one- and two-qubit pulsed gates for an oscillator stabilized Josephson qubit
Frederico Brito, David P. DiVincenzo, Roger H. Koch +1
We present theoretical schemes for performing high-fidelity one- and two-qubit pulsed gates for a superconducting flux qubit. The "IBM qubit" consists of three Josephson junctions,…
