Quantum measurement process-
To understand the measurement process in quantum, let us take an example of measurement of expectation value of any physical observable (e.g. energy average) . Average of energy in a system is given by sum of energies in different measurement by total number of measurements. But this traditional approach has problem, since after doing first measurement our system will change in quantum level and now system is not original one for second measurement.
To overcome this problem we make copies of original system (ensemble) and do measurement of energy of all copies at a single time and then take average of it.
I will be glad to see your comment if you have any query....

A quantum-mechanical effect called "tunneling" is important in electron transfer processes in biology. Quantum effects are thought to be important in other biological processes as well. First: research "quantum tunneling." Read a basic (Wikipedia-level, e.g.) description to obtain an intuitive grasp of what quantum-mechanical tunneling Then: research "quantum effects in biology." Any article on this topic is likely to include some discussion of electron transfer in photosystems; find a source that includes some discussion of other processes as well. Find...

What would be the result of a kinetic energy measurement on a free quantum particle? (i.e. potential energy V(x) = 0) of mass m with a wave-function ψ(x) = e^(-x^2) A hint for this question: Consider only the kinetic energy operator. Is the given function an eigenfunction of this operator? If yes, what will be the result of the measurement? If not an eigenfunction, what would be the result of the measurement?
