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…
Ansatz-Independent Variational Quantum Classifier
Hideyuki Miyahara, Vwani Roychowdhury
The paradigm of variational quantum classifiers (VQCs) encodes \textit{classical information} as quantum states, followed by quantum processing and then measurements to generate cl…
How much of quantum mechanics is really needed to defy Extended Church-Turing Thesis?
Leonid Gurvits, Vwani Roychowdhury, Sudhir Kumar Singh +1
This paper has been withdrawn by the author as one of the coauthors needs institutional permission.
Latency in local, two-dimensional, fault-tolerant quantum computing
Federico M. Spedalieri, Vwani P. Roychowdhury
We analyze the latency of fault-tolerant quantum computing based on the 9-qubit Bacon-Shor code using a local, two-dimensional architecture. We embed the data qubits in a 7 by 7 ar…
Robustness of entangled states that are positive under partial transposition
Somshubhro Bandyopadhyay, Sibasish Ghosh, Vwani Roychowdhury
We study robustness of bipartite entangled states that are positive under partial transposition (PPT). It is shown that almost all PPT entangled states are unconditionally robust,…
