Classifying single-qubit noise using machine learning

Travis L. Scholten, Yi-Kai Liu, Kevin Young, Robin Blume-Kohout
As quantum information processors (QIPs) grow more sophisticated, characterizing their behavior becomes harder. Larger QIPs have more properties that need to be

The National Institute of Standards and Technology is in the process of selecting one or more public-key cryptographic algorithms through a public competition

Recovering quantum gates from few average gate fidelities

Yi-Kai Liu, Ingo Roth, Richard Kueng, Shelby Kimmel, David Gross, Jens Eisert, Martin Kliesch
Characterizing quantum processes is a key task in and constitutes a challenge for the development of quantum technologies, especially at the noisy intermediate

Pseudorandom Quantum States

Yi-Kai Liu, Zhengfeng Ji, Fang Song
We propose the concept of pseudorandom quantum states, which appear random to any quantum polynomial-time adversary. It offers a computational approximation to
