QUANTUM COMPUTING - EXAMPLE 32.1 : In quantum computing, let the amplitude A = a | 0 > + b | 1 >, | a | | a | + | b | | b | = 1. Find the values of b if A = 0.8 | 0 > + b | 1 >.
QUANTUM COMPUTING - ANSWER 32.1 : Let A = a | 0 > + b | 1 > = 0.8 | 0 > + b | 1 >, then a = 0.8. When | a | | a | + | b | | b | = 1, | b | | b | = 1 - | a | | a | = 1 - 0.8 x 0.8 = 1 - 0.64 = 0.36, | b | = 0.6. Finally b = +0.6 or -0.6.

BIOPROCESS ENGINEERING - EXAMPLE 14.2 : An aqueous solution with 2.5 g of a protein dissolved in 600 cubic centimeters of a solution at 20 degree Celsius was placed in a container that has a water-permeable membrane. Water permeated through the membrane until the h - level of the solution was 0.9 cm above the pure water. (a) Calculate the absolute temperature of the solution, T in Kelvin, where T (Kelvin) = T (degree Celsius) + 273.15. (b) Calculate the osmotic pressure, P of the solution by using the formula P = hrg where h is level of the solution, r is density of water with 1000 kg per cubic meter, g = 9.81 N / kg as gravitational acceleration. (c) Calculate the concentration of the protein solution, C in kg / cubic meter. (d) Calculate the molecular weight of the protein, (MW) = CRT / P where R = 8.314 Pa cubic meter / (mol K) as ideal gas constant.
