,Breaking “Unbreakable” Codes,y contrived to demonstrate a quantum advantage. A good example is the “Deutsch-Jozsa” problem, which was described in Chapter 2. As you may recall, this problem involves deciding whether a mystery n-bit function is constant (i.e., gives the same output on all possible inputs) or balanced (i.e., give

The Crapshoot Universe,s mundane as the outcome of a coin toss or the roll of dice. At the other extreme, randomness reaches to the very core of the metaphysical profundities of quantum mechanics. Quantum physics, as it is usually taught and practiced, relies heavily on the concept of randomness. In particular, when a phy

Swatting Quantum Bugs,wrong. They go wrong in classical computers, and they go wrong in quantum computers in similar as well as novel ways. The delicate quantum superpositions and entanglements must be maintained in a bath of constantly jostling molecules, radioactive decays from the computing constituents themselves, an

It Is Now Safe to Turn Off Your Quantum Computer,mple, that a quantum bit is not necessarily a 0 or a 1, but can be a superposition of both 0 and 1 simultaneously. We have seen that a quantum bit does not necessarily have a definite bit-value until the moment after it has been read. We have seen that reading one qubit can have an effect on the val

What Can Computers Do?,antum computer surpass those of a classical computer? This is an important question because it will require a massive financial investment to create quantum computers. We have to be able to determine whether the effort and expense will be justified.
