Many-body spin rotation by adiabatic passage in spin-1/2 XXZ chains of ultracold atoms
I. Dimitrova, S. Flannigan, Y. K. Lee, H. Lin, J. Amato-Grill, N. Jepsen, I. Čepaitė, A. J. Daley, W. Ketterle

We explore an adiabatic protocol in a system of ultracold atoms in an optical lattice. A fully magnetized state is connected to a correlated zero-magnetization state (an xy-ferromagnet) by a many-body spin rotation, realized by sweeping the detuning and power of a microwave field. Our experimental and theoretical studies highlight the potential and challenges for adiabatic preparation protocols to prepare many-body eigenstates of spin Hamiltonians.

Counterdiabatic Optimised Local Driving [Blog post]
I. Čepaitė, A. J. Daley, A. Polkovnikov, C. W. Duncan

We outline a new method for speeding up adiabatic protocols which combines ideas from local counterdiabatic driving and optimal control methods, taking advantage of the strengths of each. We refer to it as Counterdiabatic Optimised Local Driving (COLD).

A Continuous Variable Born Machine
I. Čepaitė, B. Coyle, E. Kashefi

Generative Modelling has become a promising use case for near term quantum computers. In particular, due to the fundamentally probabilistic nature of quantum mechanics, quantum computers naturally model and learn probability distributions. The Born machine is an example of such a model. Here we present the Born machine within the framework of Continuous Variable Quantum Computing for the purpose of learning continuous probability distributions.

Singlet Pathway to the Ground State of Ultracold Polar Molecules
A. Yang, S. Botsi, S. Kumar, S. B. Pal, M. M. Lam, I. Čepaitė, A. Laugharn, and K. Dieckmann

We demonstrate a two-photon pathway to the ground state of 6Li40K molecules that involves only singlet-to-singlet optical transitions.
