Generalization with quantum geometry for learning unitaries

1 code implementation23 Mar 2023 Tobias Haug, M. S. Kim

Generalization is the ability of quantum machine learning models to make accurate predictions on new data by learning from training data.

Quantum machine learning of large datasets using randomized measurements

1 code implementation2 Aug 2021 Tobias Haug, Chris N. Self, M. S. Kim

Further, we efficiently encode high-dimensional data into quantum computers with the number of features scaling linearly with the circuit depth.

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.

NISQ Algorithm for Hamiltonian Simulation via Truncated Taylor Series

no code implementations9 Mar 2021 Jonathan Wei Zhong Lau, Tobias Haug, Leong Chuan Kwek, Kishor Bharti

We recover differential equation-based NISQ algorithms for Hamiltonian simulation such as quantum assisted simulator (QAS) and variational quantum simulator (VQS) as particular cases of our algorithm.

Capacity and quantum geometry of parametrized quantum circuits

1 code implementation2 Feb 2021 Tobias Haug, Kishor Bharti, M. S. Kim

We identify a transition in the quantum geometry of the parameter space, which leads to a decay of the quantum natural gradient for deep circuits.

Noisy intermediate scale quantum simulation of time dependent Hamiltonians

no code implementations19 Jan 2021 Jonathan Wei Zhong Lau, Kishor Bharti, Tobias Haug, Leong Chuan Kwek

Quantum computers are expected to help us to achieve accurate simulation of the dynamics of many-body quantum systems.

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.
