A large part of condensed matter physics concerns itself with understanding the behaviour of electrons in solids and finding ways to control them. However, in mesoscopic systems (i.e., systems with nanometer to micrometre scale), the behaviour of electrons is difficult to predict through the Schrödinger equation. Instead, it is often more...

The study of crystalline solids and condensed matter physics at large concerns itself with the new behaviors and phases of matter exhibited by elementary particles, atoms, and molecules by virtue of being assembled into a structure. These phases arise from complex microscopic behaviors, which makes it is difficult to establish rigorous...

Quantum technology is a developing field of sciencewhere devices possess novel and superior functionalities thanks to their quantum-mechanical behaviour at the nanometer scale. A typical example is a quantum computer, where information is stored in quantum states of its quantum bits. By manipulating entangled and superposition states of these...

Much of modernmesoscopic physics focuses on studying hybrid superconducting structures: systems that combine superconductors with other materials such as semiconductors, ferromagnets, and graphene. When properly engineered, these devices display emergent physical properties that are absent in their individual constituents. An early example of...

After a century from the quantum description of nature, the scientific community has laid the basis for using nature's properties to our advantage. The quantum technology vision stems from the idea of capitalizing these principles in various sectors, such as computation and communication. However, in contrast to classical processors, encoding...

By exploiting quantum mechanics, quantum computers are able to solve problems---for example in quantum chemistry---that are far out of reach of classical computers. Conventional approaches to quantum computers use qubits (quantum bits) that can either be made out of superconducting circuits (the currently leading approach used to demonstrate...

Superconductor–semiconductor hybrid devices are interesting not only for their known and potential applications but also for the associated novel physical processes. One such example is the proposal for the realization of Majorana zero-modes, which are robust against noise and have applications in quantum information processing. Although the...

Vuik, A. (author)
Nowadays, quantum computers, a promising direction of computer hardware development, suffer too much from errors caused by disturbance of qubits to compete with the state-of-the-art classical computers. Topological phases in condensed matter physics offer a solution: the topological edge states emerging in such a phase are spatially separated by...

Skolasinski, R.J. (author)
Topological insulators and topological superconductors are novel states of matter.<br/>One of the most characteristic properties of topological insulators are the topologically protected edge states.<br/>While the bulk of the material stays insulating, the edge-state conductance is quantized and topologically protected from backscattering.<br/...
