a semiconductor qubit is shown

One of the remarkable recent discoveries in information science is that quantum mechanics can lead to efficient solutions for problems that are intractable on conventional classical computers. The realization of a practical quantum computer will require the development of fundamentally new quantum hardware: circuits whose operation is intrinsically quantum mechanical, designed for the high-fidelity generation and preservation of delicate entangled states. The University of Wisconsin–Madison has emerged as a world leader in the area of quantum devices, with three cutting edge experimental efforts focused on different quantum device implementations.

The Wisconsin Quantum Institute (WQI) brings together research on quantum computing and quantum information in the following areas:

Design and implementation of superconducting, semiconducting and neutral atom qubits
Quantum sensing:
Quantum theory: modeling of devices and materials for quantum information processing.
