The Fundamental Quantum Technology Lab hosts a variety of research around spin systems in silicon with a strong focus towards quantum computing. Explore our key research areas below.
Donor spin qubits in silicon
Donor spin qubit in silicon

One of the least experimentally-researched aspects of the quantum/classical crossover is the emergence of chaos. Classical nonlinear systems behaving chaotically show an extreme sensitivity to perturbations, rendering the long term behavior unpredictable although the system is fully deterministic

Quantum Error Correction in Donor Spins in Silicon

Quantum Error Correction (QEC) is essential for developing scalable, useful quantum computers. QEC is not hardware-agnostic; each type of hardware has its own advantages and disadvantages, which must be considered when implementing QEC strategies.
