Power of unentangled measurements on two antiparallel spins
We consider a pair of antiparallel spins polarized in a random direction to encode quantum information. We wish to extract as much information as possible on the polarization direction attainable by an unentangled measurement, i.e., by a measurement, whose outcomes are associated with product states. We develop analytically the upper bound 0.7935 bits to the Shannon mutual information obtainabl...

متن کاملParallel and Anti-parallel Spins: More Differences
We show that a set of linearly independent parallel states {|−→ ni ,−→ ni 〉} can always be exactly transformed into the corresponding anti-parallel states {|−→ ni ,−−→ ni 〉} with certainty. But this is not true, in general, for a set of linearly independent anti-parallel states. Moreover, we show that for a set of linearly independent anti-parallel states one can exactly but probabilistically t...
متن کاملDistamycin-stabilized antiparallel-parallel combination (APC) DNA.
The formation of Antiparallel-Parallel-Combination (APC) DNA, a liner duplex with a segment of parallel-stranded (ps) helix flanked by conventional B-DNA, was tested with a number of synthetic oligonucleotides. The groove-binding ligand distamycin A (DstA) was used to stabilize the ps segment comprising five A x T base pairs. Two drug molecules bound per APC, one in each of the two equivalent g...
متن کاملOptimal Algorithmic Cooling of Spins
Algorithmic Cooling (AC) of Spins is potentially the first near-future application of quantum computing devices. Straightforward quantum algorithms combined with novel entropy manipulations can result in a method to improve the identification of molecules. We introduce here several new exhaustive cooling algorithms, such as the Tribonacci and k-bonacci algorithms. In particular, we present the ...
