Compressed Quantum Operators and Roots of Hermite Polynomials
Serge Adonsou, Guillaume Dauphinais, David W. Kribs +1
The fundamental position and momentum operators of quantum mechanics are unbounded, but finite rank compressions of the operators can be considered to obtain partial information on…

Hidden shift problem for complex functions
Serge Adonsou, Peter Bruin, Maris Ozols +1
We study quantum algorithms for the hidden shift problem of complex scalar- and vector-valued functions on finite abelian groups. Given oracle access to a shifted function and the…

Unified and Generalized Approach to Entanglement-Assisted Quantum Error Correction
Priya J. Nadkarni, Serge Adonsou, Guillaume Dauphinais +2
We introduce a framework for entanglement-assisted quantum error correcting codes that unifies the three original frameworks for such codes called EAQEC, EAOQEC, and EACQ under a s…
