Quantum Information Processing, Sensing and Communications: Their Myths, Realities and Futures
Lajos Hanzo, Zunaira Babar, Zhenyu Cai +6
The recent advances in quantum information processing, sensing and communications are surveyed with the objective of identifying the associated knowledge gaps and formulating a roa…
TE-PAI: Exact Time Evolution by Sampling Random Circuits
Chusei Kiumi, Bálint Koczor
Simulating time evolution under quantum Hamiltonians is one of the most natural applications of quantum computers. We introduce TE-PAI, which simulates time evolution exactly by sa…
Preparing Ground and Excited States Using Adiabatic CoVaR
Wooseop Hwang, Bálint Koczor
CoVarince Root finding with classical shadows (CoVaR) was recently introduced as a new paradigm for training variational quantum circuits. Common approaches, such as variants of th…
Low Depth Phase Oracle Using a Parallel Piecewise Circuit
Zhu Sun, Gregory Boyd, Zhenyu Cai +7
We explore the important task of applying a phase to a computational basis state . The closely related task of rotating a target qubit by an angle…
Direct Estimation of the Density of States for Fermionic Systems
Matthew L. Goh, Bálint Koczor
Simulating time evolution is one of the most natural applications of quantum computers and is thus one of the most promising prospects for achieving practical quantum advantage. He…
High-Dimensional Subspace Expansion Using Classical Shadows
Gregory Boyd, Bálint Koczor, Zhenyu Cai
We introduce a post-processing technique for classical shadow measurement data that enhances the precision of ground state estimation through high-dimensional subspace expansion; t…
Biased Estimator Channels for Classical Shadows
Zhenyu Cai, Adrian Chapman, Hamza Jnane +1
Extracting classical information from quantum systems is of fundamental importance, and classical shadows allow us to extract a large amount of information using relatively few mea…
