Quantum request-answer game with buffer model for online algorithms. Application for The Most Frequent Keyword Problem
K. Khadiev·Dec 22, 2020
We consider online algorithms as a request-answer game. An adversary that generates input requests, and an online algorithm answers. We consider a generalized version of the game that has a buffer of limited size. The adversary loads data to the buff...
The ALF (Algorithms for Lattice Fermions) project release 2.4. Documentation for the auxiliary-field quantum Monte Carlo code

The Algorithms for Lattice Fermions package provides a general code for the finite-temperature and projective auxiliary-field quantum Monte Carlo algorithm. The code is engineered to be able to simulate any model that can be written in terms of sum...
Quantum phases of matter on a 256-atom programmable quantum simulator
S. Ebadi, Tout T. Wang, H. Levine +12 more·Dec 22, 2020
Motivated by far-reaching applications ranging from quantum simulations of complex processes in physics and chemistry to quantum information processing1, a broad effort is currently underway to build large-scale programmable quantum systems. Such sys...
Wildcard error: Quantifying unmodeled errors in quantum processors
R. Blume-Kohout, K. Rudinger, E. Nielsen +2 more·Dec 22, 2020
Error models for quantum computing processors describe their deviation from ideal behavior and predict the consequences in applications. But those processors' experimental behavior -- the observed outcome statistics of quantum circuits -- are rarely ...
Quantum advantage of two-level batteries in the self-discharging process.
Alan C. Santos·Dec 22, 2020
Devices that use quantum advantages for storing energy in the degree of freedom of quantum systems have drawn attention due to their properties of working as quantum batteries (QBs). However, one can identify a number of problems that need to be adeq...
MDS linear codes with one-dimensional hull
Lin Sok·Dec 21, 2020
The hull of a linear code C is the intersection of C with its dual C⊥, where the dual is often defined with respect to Euclidean or Hermitian inner product. The Euclidean hull with low dimensions gets much interest due to its crucial role in determin...
Crosstalk Suppression for Fault-tolerant Quantum Error Correction with Trapped Ions
Pedro Parrado-Rodríguez, C. Ryan-Anderson, A. Bermudez +1 more·Dec 21, 2020
Physical qubits in experimental quantum information processors are inevitably exposed to different sources of noise and imperfections, which lead to errors that typically accumulate hindering our ability to perform long computations reliably. Progres...
Improved Strong Simulation of Universal Quantum Circuits
L. Kocia·Dec 21, 2020
We find a scaling reduction in the stabilizer rank of the twelve-qubit tensored $T$ gate magic state. This lowers its asymptotic bound to $2^{\sim 0.463 t}$ for multi-Pauli measurements on $t$ magic states, improving over the best previously found bo...
Application of quantum machine learning using the quantum variational classifier method to high energy physics analysis at the LHC on IBM quantum computer simulator and hardware with 10 qubits
S. Wu, J. Chan, W. Guan +12 more·Dec 21, 2020
One of the major objectives of the experimental programs at the LHC is the discovery of new physics. This requires the identification of rare signals in immense backgrounds. Using machine learning algorithms greatly enhances our ability to achieve th...
A Quantum Edge Detection Algorithm
Giacomo Cavalieri, D. Maio·Dec 20, 2020
The application of quantum computing to the field of image processing has produced several promising applications: quantum image representation techniques have been developed showing how, by taking advantage of quantum properties like entanglement an...
Prove-It: A Proof Assistant for Organizing and Verifying General Mathematical Knowledge
W. Witzel, Warren D. Craft, R. Carr +1 more·Dec 20, 2020
We introduce Prove-It, a Python-based general-purpose interactive theorem-proving assistant designed with the goal of making formal theorem proving as easy and natural as informal theorem proving (with moderate training). Prove-It uses a highly-flexi...
Quantum reinforcement learning in continuous action space
Shaojun Wu, Shan Jin, Dingding Wen +1 more·Dec 19, 2020
Quantum reinforcement learning (QRL) is a promising paradigm for near-term quantum devices. While existing QRL methods have shown success in discrete action spaces, extending these techniques to continuous domains is challenging due to the curse of d...
Gate-based circuit designs for quantum adder-inspired quantum random walks on superconducting qubits
