Emergent invariance and scaling properties in the collective return dynamics of a stock market
Hideyuki Miyahara, Hai Qian, Pavan Holur +1
Several works have observed heavy-tailed behavior in the distributions of returns in different markets, which are observable indicators of underlying complex dynamics. Such prior w…
Quantum Advantage in Variational Bayes Inference
Hideyuki Miyahara, Vwani Roychowdhury
Variational Bayes (VB) inference algorithm is used widely to estimate both the parameters and the unobserved hidden variables in generative statistical models. The algorithm -- ins…
Quantum Approximation of Normalized Schatten Norms and Applications to Learning
Yiyou Chen, Hideyuki Miyahara, Louis-S. Bouchard +1
Efficient measures to determine similarity of quantum states, such as the fidelity metric, have been widely studied. In this paper, we address the problem of defining a similarity…
Decoherence Mitigation by Embedding a Logical Qubit in a Qudit
Hideyuki Miyahara, Yiyou Chen, Vwani Roychowdhury +1
Quantum information stored in a qubit is rapidly lost to the environment. The realization of robust qubits is one of the most important challenges in quantum computing. Herein we p…
