Timelessness Strictly inside the Quantum Realm

Quantum Game Theory: Within the Realm of Quantum Strategies

This article was written for this year’s seminars of Introdução à Investigação. Its general subject is the quantization of Game Theory and the results which ensue. Firstly, a brief revision of the terminology of Game Theory is given. Afterwards, Meyer’s quantization of the Penny Flip is used as a motivation for quantizing the classical games. In a final section, Eisert’s scheme of quantization ...

Being Inside the Quantum Atom

This article explores the possibility of using dynamic Educational Virtual Environments (EVEs) for helping students with limited background in physics and mathematics to deeply understand Quantum Mechanics principles and create the correct mental images of atomic models. Taking under consideration the results of our pilot study we have created “The Quantum Atom”, an educational environment with...

Strictly contractive quantum channels and physically realizable quantum computers

We study the robustness of quantum computers under the influence of errors modelled by strictly contractive channels. A channel T is defined to be strictly contractive if, for any pair of density operators ρ, σ in its domain, ‖Tρ− Tσ‖1 ≤ k ‖ρ− σ‖1 for some 0 ≤ k < 1 (here ‖·‖1 denotes the trace norm). In other words, strictly contractive channels render the states of the computer less distingui...

Inside the quantum mechanics lecture: Changing practices

Quantum mechanics is one of the most diffi cult subjects to learn or teach but it has only recently become the focus of educational research. Studies have documented common misconceptions and areas of diffi culty by examining student performance, but have not independently explored current teaching practice. In this study, an audit of all quantum mechanics classes was conducted over the spring ...
