QuICS is a partnership between @UofMaryland and @NIST. We advance research and education in quantum computer science and quantum information theory.

College Park, MD
The August cover of @NaturePhysics features work by researchers affiliated @JointQuICS. The paper—coauthored by @QiZhao_Quantum and @andrewmchilds—shows that quantum simulation algorithms can be faster in the presence of entanglement. Learn more: nature.com/nphys/volumes/21/…

A new study @PhysRevLett shows that some quantum states previously thought to provide the "magic" needed for quantum computation can actually be simulated efficiently by classical computers. The findings redefine scientists’ understanding of the boundary between classical and quantum computing, and identify a more precise resource required for achieving a genuine quantum advantage. The study was coauthored by @JointQuICS Fellow @nicoleyh11, and @ParticulateDave and J.J. Thio from the University of Cambridge's @DeptofPhysics. Learn more: go.umd.edu/2dm8

Looking forward to visiting Rochester for “Quantum Thermodynamics and Decoherence” this week. If you’re in the area, stop by at least for the public lecture! Author Mark Alpert will talk about bridging quantum science and writing. @umiacs umiacs.umd.edu/news-events/n…

Researchers @JointQuICS are on 2 of the 5 teams selected as finalists in the $5 million @xprize Quantum Applications competition, which challenges teams to demonstrate where quantum computing can deliver meaningful advantage over classical approaches. @UofMaryland Ph.D. students Mahathi Vempati (@mahathi_vempat) and Jeffery Yu, along with their adviser Andrew Childs (@andrewmchilds), collaborated with researchers @UMich to develop a hybrid classical-quantum algorithm to solve the neutron diffusion k-eigenvalue problem, modeling nuclear criticality in heterogeneous media. Such calculations are essential for designing safe reactors, managing nuclear fuel, and modeling radiation behavior. @JointQuICS Fellow Michael Gullans is part of a multi-institutional team that developed a framework for simulating chemistry and material properties that compute closer to underlying physics by using native fermion and boson degrees of freedom. They showed significant resource savings relative to conventional qubit-based approaches. This framework could help address pressing challenges across industry and advanced manufacturing that require material properties that depend on quantum interactions. As the finalists enter Phase II of the competition—a stage defined by deeper technical validation, benchmarking, and execution—they will further develop their solutions with an emphasis on realistic hardware assumptions and constraints, direct quantitative comparison to leading classical methods, and clear demonstration of performance improvements and potential for real-world adoption. xprize.org/news/from-wildcar…

Collaborators and I noticed that many quantum metrologists apply effective time reversals, but in (sometimes radically) different ways and often without knowing of each other's work. This perspective bridges the gaps and highlights new ones. arxiv.org/abs/2601.20952

Most quantum information scientists detest the noise that erodes the performance of quantum computers. @JointQuICS postdoctoral fellow Yuxin Wang sees the glass as half-full: noise is a fascinating subject to study. From this week's @JQInews Seminar.

New work by researchers @NIST & @JointQuICS to make entangled qubits more robust against noise, and therefore a promising route to real-world quantum sensors, was published @PhysRevLett. The paper's coauthors are Cheng-Ju (Jacob) Lin, Zi-Wen Liu, Victor Albert (@victorvalbert) and Alexey Gorshkov.
Entangled particles could be the best sensors yet if we can make them to survive environmental noise. Physicists found a way to make them more robust, keeping their sensitivity while reducing their weakness to noise. nist.gov/news-events/news/20…

David Gross (Cologne) talks about SDP based quantum algorithms. Take home: hidden constants matter. Even if there is an asymptotic speedup in your favorite use case, it may still not be in the parameter regime that is relevant to the problem size you're interested in.
