Hamiltonian learning is an important procedure in quantum system identification, calibration, and successful operation of quantum computers.

We proposed an alternative framework, called dither computing, that combines aspects of stochastic computing and its deterministic variants and that can perform computing with similar efficiency, is unbiased, and with a variance and MSE also on the optimal order of $\Theta(\frac{1}{N^2})$.

We consider a new family of stochastic operators for reinforcement learning with the goal of alleviating negative effects and becoming more robust to approximation or estimation errors.

We consider a new form of reinforcement learning (RL) that is based on opportunities to directly learn the optimal control policy and a general Markov decision process (MDP) framework devised to support these opportunities.

We consider the use of look-up tables (LUT) to simplify the hardware implementation of a deep learning network for inferencing after weights have been successfully trained.

We show that good accuracy on MNIST and Fashion MNIST can be obtained using a relatively small number of trainable parameters.

For this metric, the positions of the bits are not relevant to the decoding, and in many noise models, not relevant to the BER either.

We explore the possibility of using machine learning to identify interesting mathematical structures by using certain quantities that serve as fingerprints.
