The GHZ effect is, in the physicist Sidney Coleman’s words, “quantum mechanics in your face.” It demolishes a deeply embedded prejudice, rooted in everyday experience, that physical systems have definite properties, independent of whether those properties are measured. For if they did, then ...
Nevertheless, quantum effects in biology are evident in daily life. Two major concepts of quantum mechanics govern their operation. The first is the quantized behavior of physical properties like energy and momentum. A simple demonstration is related toquantized energy levels(seeGlossary) confined in ...
For this reason, the Wigner’s Friend Paradox cannot be regarded as an argument that rules out quantum mechanics as a universally valid theory. In this work we propose a Gedankenexperiment that extends Wigner’s setup. It consists of agents who are using quantum theory to reason about other ...
Entanglement is a central subject in quantum mechanics. Due to its genuine relativistic behavior and fundamental nature, high-energy colliders are attractive systems for the experimental study of fundamental aspects of quantum mechanics. We propose the detection of entanglement between the spins of top...

The computational efficiency of quantum mechanics can be characterized in terms of the qubit circuit model, which is defined by a few simple properties: each computational gate is a reversible transformation in a connected matrix group; single wires carry quantum bits, i.e. states of a three-dim...
Quantum mechanics describes these, and other physical phenomena extraordinarily well. We begin with a simple experiment that you can do for a few dollars worth of equipment. Begin with a beam of light passing through a polarizer, as in Fig. 1. Sign in to download full-size image Fig. 1....
1 An electron in a square quantum well is the classic particle-in-a-box of basic quantum mechanics. The electron cannot have just any energy inside the well: rather, it is constrained to reside in certain discrete energy levels, i.e., its energy is quantized. These allowed energy levels,...

This paper is a ‘spiritual child’ of the 2005 lecture notes Kindergarten Quantum Mechanics Coecke (2005) [24], which showed how a simple, pictorial extension of Dirac notation allowed several quantum features to be easily expressed and derived, using language even a kindergartner can understand...
