Characterizing quantum circuits with qubit functional configurations
Zixuan Hu, Sabre Kais
We propose a theory of characterizing quantum circuits with qubit functional configurations. Any quantum circuit can be decomposed into alternating sequences of 1-qubit unitary gat…
The quantum condition space
Zixuan Hu, Sabre Kais
In this work we first propose to exploit the fundamental properties of quantum physics to evaluate the probability of events with projection measurements. Next, to study what event…
Relaxation of a Stationary State on a Quantum Computer Yields Unique Spectroscopic Fingerprint of the Computer's Noise
Scott E. Smart, Zixuan Hu, Sabre Kais +1
Quantum computing has the potential to revolutionize computing for certain classes of problems with exponential scaling, and yet this potential is accompanied by significant sensit…
Statistical Approach to Quantum Phase Estimation
Alexandria J. Moore, Yuchen Wang, Zixuan Hu +2
We introduce a new statistical and variational approach to the phase estimation algorithm (PEA). Unlike the traditional and iterative PEAs which return only an eigenphase estimate,…
A practical quantum encryption protocol with varying encryption configurations
Junxu Li, Zixuan Hu, Sabre Kais
Quantum communication is an important application that derives from the burgeoning field of quantum information and quantum computation. Focusing on secure communication, quantum c…
A general quantum algorithm for open quantum dynamics demonstrated with the Fenna-Matthews-Olson complex
Zixuan Hu, Kade Head-Marsden, David A. Mazziotti +2
Using quantum algorithms to simulate complex physical processes and correlations in quantum matter has been a major direction of quantum computing research, towards the promise of…
