Quantum Hardware
The Quantum Hardware group at CIC nanoGUNE focuses on the development of physical hardware for quantum information processing using devices based on semiconducting, superconducting and hybrid materials.
Silicon-based quantum computing
We leverage the very same hardware that is used in standard electronics, the silicon transistor, for quantum computing applications.

Quantum charge/spin sensing
We use semiconducting-superconducting hybrid systems to reach the ultimate limits of charge and spin detection sensitivity.

Quantum-dots based microwave devices
We use semiconductor quantum dots at microwave frequencies to demonstrate new and more efficient electronic devices and circuits such as amplifiers, multipliers and sensors.
