Quantum computing is an exciting new field of research that has begun in recent years to yield practical processing devices. Quantum mechanics is the branch of physics that applies at the microscopic sub-atomic level. Here, the normal laws of physics that govern how we live no longer apply, c...
This is usually described as "unconditional security", although there are some minimal assumptions required, including that the laws of quantum mechanics apply and that Alice and Bob are able to authenticate each other, i.e. Eve should not be able to impersonate Alice or Bob as otherwise a ...

As the theory of the atom, quantum mechanics is perhaps the most successful theory in the history of science. It enables physicists, chemists, and technicians to calculate and predict the outcome of a vast number of experiments and to create new and advanced technology based on the insight into...
The crux of the matter is the privileged role of the observer in quantum theory. Every interpretation of quantum mechanics is formulated in terms of what an observer expects to see or measure (any other formulation would be unscientific). This dichotomy between the observer and (quantum) system...
In general, it is true in quantum mechanics that one can give definite answers only for ensembles. So one has to bear in mind that, in general, no definite assertions about a single particle can be made. Indeed, there are many examples of situations which remain paradoxical from the perspec...
Quantum computing is one of the most potentially transformative applications of quantum mechanics to technology. Representing data quantum mechanically allows one to compute in a fundamentally new way. Information can be stored in quantum degrees of freedom, such as the internal state of an ion, or...
As for practical examples, Akkerman showed a calculation of a series of waveguides laid out in a Sierpinski gasket pattern (the gasket is pictured above). He showed that, even if the gasket is terminated at just five iterations, the divergence between two volumes (areas in this case, since ...
It’s sort of the iconic mystery of quantum mechanics: we know that an electron can be in two places at once – in a ‘superposition’ – but when we measure it, it’s only ever seen to be in one place, picked seemingly at random from the two possibilities. We say the state has ...
推荐 内容简介· ··· An accessible introduction to advanced quantum theory, this graduate-level textbook focuses on its practical applications rather than mathematical technicalities. It treats real-life examples, from topics ranging from quantum transport to nanotechnology, to equip students with a to...
