Designing dynamically corrected gates robust to multiple noise sources using geometric space curves
Hunter T. Nelson, Evangelos Piliouras, Kyle Connelly +1
Noise-induced gate errors remain one of the main obstacles to realizing a broad range of quantum information technologies. Dynamical error suppression using carefully designed cont…
Deterministic generation of qudit photonic graph states from quantum emitters
Zahra Raissi, Edwin Barnes, Sophia E. Economou
We propose and analyze deterministic protocols to generate qudit photonic graph states from quantum emitters. We show that our approach can be applied to generate any qudit graph s…
TETRIS-ADAPT-VQE: An adaptive algorithm that yields shallower, denser circuit ansätze
Panagiotis G. Anastasiou, Yanzhu Chen, Nicholas J. Mayhall +2
Adaptive quantum variational algorithms are particularly promising for simulating strongly correlated systems on near-term quantum hardware, but they are not yet viable due, in lar…
Performance analysis of quantum repeaters enabled by deterministically generated photonic graph states
Yuan Zhan, Paul Hilaire, Edwin Barnes +2
By encoding logical qubits into specific types of photonic graph states, one can realize quantum repeaters that enable fast entanglement distribution rates approaching classical co…
Symmetry breaking slows convergence of the ADAPT Variational Quantum Eigensolver
Luke W. Bertels, Harper R. Grimsley, Sophia E. Economou +2
Because quantum simulation of molecular systems is expected to provide the strongest advantage over classical computing methods for systems exhibiting strong electron correlation,…
Scaling adaptive quantum simulation algorithms via operator pool tiling
John S. Van Dyke, Karunya Shirali, George S. Barron +3
Adaptive variational quantum simulation algorithms use information from the quantum computer to dynamically create optimal trial wavefunctions for a given problem Hamiltonian. A ke…
