Sharp complexity phase transitions generated by entanglement
Soumik Ghosh, Abhinav Deshpande, Dominik Hangleiter +2
Entanglement is one of the physical properties of quantum systems responsible for the computational hardness of simulating quantum systems. But while the runtime of specific algori…
General quantum algorithms for Hamiltonian simulation with applications to a non-Abelian lattice gauge theory
Zohreh Davoudi, Alexander F. Shaw, Jesse R. Stryker
With a focus on universal quantum computing for quantum simulation, and through the example of lattice gauge theories, we introduce rather general quantum algorithms that can effic…
Quantum algorithms and the power of forgetting
Andrew M. Childs, Matthew Coudron, Amin Shiraz Gilani
The so-called welded tree problem provides an example of a black-box problem that can be solved exponentially faster by a quantum walk than by any classical algorithm. Given the na…
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.…
Sample-optimal classical shadows for pure states
Daniel Grier, Hakop Pashayan, Luke Schaeffer
We consider the classical shadows task for pure states in the setting of both joint and independent measurements. The task is to measure few copies of an unknown pure state in…
Quantum differential equation solvers: limitations and fast-forwarding
Dong An, Jin-Peng Liu, Daochen Wang +1
We study the limitations and fast-forwarding of quantum algorithms for linear ordinary differential equation (ODE) systems with a particular focus on non-quantum dynamics, where th…
Continuous-variable quantum state designs: theory and applications
Joseph T. Iosue, Kunal Sharma, Michael J. Gullans +1
We generalize the notion of quantum state designs to infinite-dimensional spaces. We first prove that, under the definition of continuous-variable (CV) state -designs from Comm.…
Pauli topological subsystem codes from Abelian anyon theories
Tyler D. Ellison, Yu-An Chen, Arpit Dua +3
We construct Pauli topological subsystem codes characterized by arbitrary two-dimensional Abelian anyon theories--this includes anyon theories with degenerate braiding relations an…
Understanding the development of interest and self-efficacy in active-learning undergraduate physics courses
Remy Dou, Eric Brewe, Geoff Potvin +2
Modeling Instruction (MI), an active-learning introductory physics curriculum, has been shown to improve student academic success. Peer-to-peer interactions play a salient role in…
Quantum Algorithms for Geologic Fracture Networks
Jessie M. Henderson, Marianna Podzorova, M. Cerezo +4
Solving large systems of equations is a challenge for modeling natural phenomena, such as simulating subsurface flow. To avoid systems that are intractable on current computers, it…
Deterministic constant-depth preparation of the AKLT state on a quantum processor using fusion measurements
Kevin C. Smith, Eleanor Crane, Nathan Wiebe +1
The ground state of the spin-1 Affleck, Kennedy, Lieb and Tasaki (AKLT) model is a paradigmatic example of both a matrix product state and a symmetry-protected topological phase, a…
Selection and improvement of product formulae for best performance of quantum simulation
Mauro E. S. Morales, Pedro C. S. Costa, Giacomo Pantaleoni +3
Quantum algorithms for simulation of Hamiltonian evolution are often based on product formulae. The fractal methods give a systematic way to find arbitrarily high-order product for…
Lower Bounds on Quantum Annealing Times
Luis Pedro García-Pintos, Lucas T. Brady, Jacob Bringewatt +1
The adiabatic theorem provides sufficient conditions for the time needed to prepare a target ground state. While it is possible to prepare a target state much faster with more gene…

We use non-equilibrium steady states to study the effect of dissipation-assisted operator evolution (DAOE) on the scaling behavior of transport in one-dimensional spin chains. We c…
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…
Holographic measurement and bulk teleportation
Stefano Antonini, Gregory Bentsen, ChunJun Cao +3
Holography has taught us that spacetime is emergent and its properties depend on the entanglement structure of the dual theory. In this paper, we describe how changes in the entang…
