TIQI - Trapped Ion Quantum Information

Our group is interested in investigating experimentally the role of information in quantum mechanics, and the transition between quantum and classical dynamics. The two are closely related - when a quantum system interacts with its environment, the loss of coherence in the system is due to sharing of information with the environment. We would like to investigate this in a controlled manner, by precision control of the system, environment, and the coupling between the two. We are simultaneously developing new methods for quantum state generation and quantum information processing with trapped atomic ions.

Quantum interference between two different locations. D. Kienzler et al. Phys. Rev. Lett. 116, 140402 (2016)

We observe directly the quantum interference between an atom superposed at two locations separated by 240 nm. We use a squeezed reconstruction to access large quantum states - the largest "Schrodinger's cats" observed to date. Read more 


Estimation of a general single-qubit Hamiltonian. L.E. de Clerq et al. Nature Comms. 7, 11218 (2016)

We devise a method for reconstructing any unknown Hamiltonian on a single spin, and demonstrate it using a single travelling ion.  Read more
