9) i=0 where ik refers to the binary scalar product of the two decimal numbers considering them as binary vectors (sum of bitwise products modulo 2). Next we use the Hadamard gate to emphasize the superposition principle which proves to be often very useful when analyzing quantum circuits or algorithms. 6). The same results can be achieved if the gate is feeded with each computational basis state individually and the results are 22 QUANTUM COMPUTING BASICS added together. 6)) the applicability of the superposition principle.

5. Third Postulate (measurement): Any quantum measurement can be described by means of a set of measurement operators {Mm }, where m stands for the possible results of the measurement. The probability of measuring m if the system is in state v can be calculated as † Mm v, P (m | v) = v† Mm and the system after measuring m goes to state v = Mm v † v† Mm Mm v . 6260755 · 10−34 Js. m QBITS AND QREGISTERS 15 measurement operators have to satisfy the following completeness relation † Mm Mm ≡ I. m Measurements are obviously not reversible and therefore they represent the only exception under the unitarity constraint.

Remark: Let us throw some light upon the close connection between the measuring apparatus and the measured object using the widely known microscopy. Optical microscopes use the reflected photons from the object’s surface. To achieve reflection the half-wavelength of the photon (more precisely light is considered as a wave at this point) has to be smaller than the unevenness of the surface. g. X-rays. On the other hand the light can be regarded as a series of photons. Each photon has its mass and thus its energy which depends on the frequency of the light.
