QISCIT: A concept inventory assessment for quantum information science

Kelley Durkin, Manshuo Lin, Michael Kolodrubetz, Ryan P. McMahan

Quantum information science (QIS) is a critical interdisciplinary field, deeply rooted in physics, that requires a well-educated workforce in the near future. Numerous researchers and educators have been actively investigating how to best educate and prepare such a workforce. An open issue …

Topological anomalous Floquet photon pump

Saeed Rahmanian Koshkaki, Mohsen Yarmohammadi, Michael Kolodrubetz

There is a close theoretical connection between topological Floquet physics and cavity QED, yet this connection has not been realized experimentally due to complicated cavity QED models that often arise. We propose a simple, experimentally viable protocol to realize non-adiabatic topological photon …

Scalable Spin Squeezing in Power-Law Interacting XXZ Models with Disorder

Samuel E. Begg, Bishal Ghosh, Chong Zu, Chuanwei Zhang et autres

While spin squeezing has been traditionally considered in all-to-all interacting models, recent works have shown that it can also occur in systems with power-law interactions, enabling direct tests in Rydberg atoms, trapped ions, ultracold atoms, and nitrogen-vacancy (NV) centers in diamond. For …

Coherent matter wave emission from an atomtronic transistor

Sasanka Dowarah, M. C. Du, Alan Zanders, Shengwang Du et autres

The atomtronic matter-wave triple-well transistor is theoretically predicted to exhibit current gain and act as a coherent matter-wave emitter. In this work, we investigate the dynamics of an atomtronic transistor composed of a triple-well potential -- source, gate, and drain -- modeled …

Ultrafast dynamics of a fermion chain in a terahertz field-driven optical cavity

Mohsen Yarmohammadi, John Sous, Marin Bukov, Michael Kolodrubetz

The authors study here ultrafast dynamics in a fermion chain within a terahertz laser-driven optical cavity, coupled to infrared-active phonons. Realistic photon loss in low-quality cavities blocks first-order phase transitions and polariton formation. In high-quality cavities, strong laser drives sustain transitions in …

Cavity induced many-body localization

Rong-Chun Ge, Saeed Rahmanian Koshkaki, Michael Kolodrubetz

In this paper, we explore the feasibility of achieving many-body localization in the context of cavity quantum electrodynamics at strong coupling. Working with a spinless electronic Hubbard chain sitting coupled to a single-mode cavity, we show that the global coupling between electrons …

Phases and phase transition in Grover's algorithm with systematic noise

Sasanka Dowarah, Chuanwei Zhang, Vedika Khemani, Michael Kolodrubetz

While limitations on quantum computation under Markovian environmental noise are well understood in generality, their behavior for different quantum circuits and noise realizations can be less universal. Here we consider a canonical quantum algorithm---Grover's algorithm for unordered search on $L$ qubits---in the …

Zeno physics of the Ising chain with symmetry-breaking boundary dephasing

Umar Javed, Riccardo J. Valencia-Tortora, Jamir Marino, Vadim Oganesyan et autres

In few-qubit systems, the quantum Zeno effect arises when measurement occurs sufficiently frequently that the spins are unable to relax between measurements. This can compete with Hamiltonian terms, resulting in interesting relaxation processes which depend nonmonotonically on the ratio of measurement rate …

Probing topological phases in a perturbed Kane-Mele model via RKKY interaction: Application to monolayer jacutingaite Pt 2 HgSe 3

Mohsen Yarmohammadi, Saeed Rahmanian Koshkaki, Jamal Berakdar, Marin Bukov et autres

Quantum spin Hall insulators (QSHIs) leverage strong spin-orbit coupling (SOC) for efficient spin manipulation, making them promising for spintronics. In this study, we investigate the noncollinear Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between two magnetic impurities in a perturbed Kane-Mele model with strong SOC, relevant …
