Quantum error correction well below the color code threshold
Ali Lavasani, Adam P. Reed, Joan M. Dreiling +20
Quantum error correction enables scalable fault-tolerant quantum computation by suppressing logical errors exponentially with code distance once physical error rates fall below a c…
Superconducting pairing correlations on a trapped-ion quantum computer
Etienne Granet, Sheng-Hsuan Lin, Kevin Hémery +31
The Fermi-Hubbard model is the starting point for the simulation of many strongly correlated materials, including high-temperature superconductors, whose modelling is a key motivat…
Digital quantum magnetism on a trapped-ion quantum computer
Reza Haghshenas, Eli Chertkov, Michael Mills +56
Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…
Tensor networks for quantum computing
Aleksandr Berezutskii, Minzhao Liu, Atithi Acharya +25
In the rapidly evolving field of quantum computing, tensor networks serve as an important tool due to their multifaceted utility. In this paper, we review the diverse applications…
The computational power of random quantum circuits in arbitrary geometries
Matthew DeCross, Reza Haghshenas, Minzhao Liu +49
Empirical evidence for a gap between the computational powers of classical and quantum computers has been provided by experiments that sample the output distributions of two-dimens…
Probing critical states of matter on a digital quantum computer
Reza Haghshenas, Eli Chertkov, Matthew DeCross +11
Although quantum mechanics underpins the microscopic behavior of all materials, its effects are often obscured at the macroscopic level by thermal fluctuations. A notable exception…
Qubit-efficient simulation of thermal states with quantum tensor networks
Yuxuan Zhang, Shahin Jahanbani, Daoheng Niu +2
We present a holographic quantum simulation algorithm to variationally prepare thermal states of -dimensional interacting quantum many-body systems, using only enough hardware q…
Simulating challenging correlated molecules and materials on the Sycamore quantum processor
Ruslan N. Tazhigulov, Shi-Ning Sun, Reza Haghshenas +6
Simulating complex molecules and materials is an anticipated application of quantum devices. With strong quantum advantage demonstrated in artificial tasks, we examine how such adv…
The Variational Power of Quantum Circuit Tensor Networks
Reza Haghshenas, Johnnie Gray, Andrew C. Potter +1
We characterize the variational power of quantum circuit tensor networks in the representation of physical many-body ground-states. Such tensor networks are formed by replacing the…
