The significance of quantum computation for cryptography is discussed. Following a brief survey of the requirements for quantum computational hardware, an overview of the ion trap quantum computation project at Los Alamos is presented. The physical limitations to quantum computation with trapped ions are analyzed and an assessment of the computational potential of the technology is made.

Hydrogen and deuterium Rydberg atoms, initially moving at velocities of 600 m/s and 560 m/s, respectively, in pulsed supersonic beams, have been decelerated and electrostatically trapped following adiabatic 90◦ deflection from their initial axis of propagation to minimise collisions with the trailing edge of the gas pulses. The time evolution of the potential energy surfaces, over which the ato...

The universal mercury vapor black light trap is an effective device used for collecting moth specimens in a wide variety of habitats; yet, they can present challenges for researchers. The mercury vapor trap is often powered by a heavy automotive battery making it difficult to conduct extensive surveys in remote regions. The mercury vapor trap also carries a considerable financial cost per trap ...

An 11-subunit protein called trp RNA binding Attenuation Protein (TRAP) controls attenuation of the tryptophan biosynthetic (trpEDCFBA) operon in Bacillus subtilis. Tryptophan-activated TRAP binds to 11 (G/U)AG repeats in the 5' leader region of trp mRNAs, and downregulates expression of the operon by promoting transcription termination prior to the structural genes. Anti-TRAP (AT) is an antago...

two continuously regenerating traps crt-a and crt-b were evaluated under the controlled carbonyl emissions from a turbocharged diesel engine run on an ac electrical dynamometer. the gas-phase carbonyls were taken in silica gel cartridges coated with 2,4-dinitrophenylhydrazine both upstream (baseline) and downstream of the traps, and a total of fourteen carbonyls were identified and then quantif...
