Quantum Properties and Molecular Theory Lab
Machine-translated · View original
A theory lab that explores superconductivity in cuprates and considers its application to qubits.

AboutAbout the lab
Understanding how superconductivity works from theory.
The Quantum Properties and Molecular Theory Lab is a theoretical lab whose research keywords are cuprate superconductors and quantum computers.
Using quantum mechanical theory, the lab investigates the currents that flow in superconductors, the phase transition between the superconducting and normal states, and related phenomena.
The lab also studies whether the spin-vortex-induced loop current that appears in thin films of cuprates can be used as a qubit.
The lab's website goes by the name "KOIZUMI LAB," and the site shows the Center for Computational Sciences.
Key terms
- Cuprate superconductor
- A material containing copper and oxygen that shows superconductivity, in which electrical resistance drops to zero.
- Berry connection
- In quantum mechanics, a mathematical quantity that describes how the phase of the wave function representing a state changes.
- Qubit
- The basic unit that carries information in a quantum computer.
ResearchResearch themes
The lab studies superconductivity from the standpoint of quantum mechanical theory, with cuprate superconductors and quantum computers as its research keywords. Its recent papers deal with a theory of superconductivity using the Berry connection and with the application of superconductor thin films to qubits.
