Quantum Search of Spatial Regions
: Can Grover’s algorithm speed up search of a physical region—for example a 2-D grid of size √ n × √ n? The problem is that √ n time seems to be needed for each query, j...

Lower bounds for Quantum Oblivious Transfer
Oblivious transfer is a fundamental primitive in cryptography. While perfect information theoretic security is impossible, quantum oblivious transfer protocols can limit the disho...

Axiomatic Description of Mixed States From Selinger's CPM-construction
We recast Selinger's CPM-construction of completely positive maps [11] as an axiomatization of maximally mixed states. This axiomatization also guarantees categories of compl...

Controllability of the rotation of a quantum planar molecule
Abstract— We consider the simplest model for controlling the rotation of a molecule by the action of an electric field, namely a quantum planar pendulum. This problem consists i...

Alternative Computational Models: A Comparison of Biomolecular and Quantum Computation
Molecular Computation (MC) is massively parallel computation where data is stored and processed within objects of molecular size. Biomolecular Computation (BMC) is MC using biotec...
