Entanglement and quantum computing

Entanglement is a robust quantifier of quantum correlationsin many-body systems. We do analytical studies of entanglement in spin chains, low-dimensional gases, and Gaussian states. In many cases of interest, subsystems of pure states at zero temperature display quantum fluctuations with the same statistical properties as in effective thermal models.

SanD also performs numerical simulations of quantum algorithms like Grover's algorithm in order to gain a deeper understanding of how experimental conditions can affect implementations of quantum computing.
