Robustness of cluster states and surface code states against random local fields

2019 · arXiv (Cornell University)

In ideal quantum circuits, qubits are tacitly assumed to be uniformly fabricated and operated by prescribed signals. In reality, however, we must cope with different control signals to adjust individual qubits, which requires a large …

Three Learning Stages and Accuracy-Efficiency Tradeoff of Restricted Boltzmann Machines

2022 · arXiv (Cornell University)

Restricted Boltzmann Machines (RBMs) offer a versatile architecture for unsupervised machine learning that can in principle approximate any target probability distribution with arbitrary accuracy. However, the RBM model is usually not directly accessible due to …
