Noisy intermediate-scale quantum algorithm for semidefinite programming

1 code implementation7 Jun 2021 Kishor Bharti, Tobias Haug, Vlatko Vedral, Leong-Chuan Kwek

Unlike variational quantum eigensolvers, the classical optimization program of our eigensolver is convex, can be solved in polynomial time with the number of ansatz parameters and every local minimum is a global minimum.

Engineering quantum current states with machine learning

1 code implementation21 Nov 2019 Tobias Haug, Rainer Dumke, Leong-Chuan Kwek, Christian Miniatura, Luigi Amico

With our approach, quantum current states characterized by a single winding number or entangled currents with two winding numbers can be prepared superseding the existing protocols.

Andreev-reflection and Aharonov-Bohm dynamics in atomtronic circuits

1 code implementation10 Jul 2018 Tobias Haug, Rainer Dumke, Leong-Chuan Kwek, Luigi Amico

We find that the steady-state is independent of the flux, however the actual time-dynamics depends on the flux.
