Orbital-optimized pair-correlated electron simulations on trapped-ion quantum computers
Luning Zhao, Joshua Goings, Kenneth Wright +8
Variational quantum eigensolvers (VQE) are among the most promising approaches for solving electronic structure problems on near-term quantum computers. A critical challenge for VQ…
Continuous Symmetry Breaking in a Trapped-Ion Spin Chain
Lei Feng, Or Katz, Casey Haack +5
One-dimensional systems exhibiting a continuous symmetry can host quantum phases of matter with true long-range order only in the presence of sufficiently long-range interactions.…
Angle-robust Two-Qubit Gates in a Linear Ion Crystal
Zhubing Jia, Shilin Huang, Mingyu Kang +4
In trapped-ion quantum computers, two-qubit entangling gates are generated by applying spin-dependent force which uses phonons to mediate interaction between the internal states of…
Experimental Implementation of an Efficient Test of Quantumness
Laura Lewis, Daiwei Zhu, Alexandru Gheorghiu +11
A test of quantumness is a protocol where a classical user issues challenges to a quantum device to determine if it exhibits non-classical behavior, under certain cryptographic ass…
Demonstration of three- and four-body interactions between trapped-ion spins
Or Katz, Lei Feng, Andrew Risinger +2
Quantum processors use the native interactions between effective spins to simulate Hamiltonians or execute quantum gates. In most processors, the native interactions are pairwise,…
Engineering dynamically decoupled quantum simulations with trapped ions
W. Morong, K. S. Collins, A. De +3
An external drive can improve the coherence of a quantum many-body system by averaging out noise sources. It can also be used to realize models that are inaccessible in the static…
