Autor: De, Arinjoy, Lerose, Alessio, Luo, De, Surace, Federica M., Schuckert, Alexander, Bennewitz, Elizabeth R., Ware, Brayden, Morong, William, Collins, Kate S., Davoudi, Zohreh, Gorshkov, Alexey V., Katz, Or, Monroe, Christopher

Spontaneous particle-pair formation is a fundamental phenomenon in nature. It can, for example, appear when the potential energy between two particles increases with separation, as if they were connected by a tense string. Beyond a critical separatio

Exponential entanglement advantage in sensing correlated noise

Autor: Wang, Yu-Xin, Bringewatt, Jacob, Seif, Alireza, Brady, Anthony J., Oh, Changhun, Gorshkov, Alexey V.

In this work, we propose a new form of exponential quantum advantage in the context of sensing correlated noise. Specifically, we focus on the problem of estimating parameters associated with Lindblad dephasing dynamics, and show that entanglement ca

In order to solve problems of practical importance, quantum computers will likely need to incorporate quantum error correction, where a logical qubit is redundantly encoded in many noisy physical qubits. The large physical-qubit overhead typically as

RISC-V RVV efficiency for ANN algorithms

Autor: Rumyantsev, Konstantin, Yakovlev, Pavel, Gorshkov, Andrey, Sokolov, Andrey P.

Handling vast amounts of data is crucial in today's world. The growth of high-performance computing has created a need for parallelization, particularly in the area of machine learning algorithms such as ANN (Approximate Nearest Neighbors). To improv

Div-curl problem for non-solenoidal flows with infinite energy and no-slip boundary condition

Autor: Gorshkov, Aleksei

In the paper we study div-curl problem in exterior domain with given condition on infinity and no-slip boundary condition. We will derive moment relations on vorticity and divergence for uniqueness solvability of the problem and present $L_2$-estimat
