Entanglement and magic transitions in an all-to-all non-Hermitian spin model
Sasanka Dowarah, Michael Kolodrubetz
The long-time state of a non-Hermitian system is determined by the eigenvalue with the largest imaginary part. In interacting many-body systems this eigenvalue usually cannot be tr…
Mitigating Noise-Induced Barren Plateaus Using a Non-Unitary Ansatz: Application to Molecular Electronic Transport
Sasanka Dowarah, Abeda Sultana Shamma, Yazdan Maghsoud +2
Variational quantum algorithms (VQAs) offer a promising route toward simulating many-body quantum systems on noisy intermediate-scale quantum (NISQ) hardware. However, their scalab…
Scalable Spin Squeezing in Power-Law Interacting XXZ Models with Disorder
Samuel E. Begg, Bishal K. Ghosh, Chong Zu +2
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, enab…
Coherent matter wave emission from an atomtronic transistor
Sasanka Dowarah, Mengxin Du, Alan Zanders +3
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 dyn…
Robust qubit interactions mediated by photonic topological edge states
Boris Gurevich, Weihua Xie, Mohsen Yarmohammadi +1
We investigate the coupling of two spatially separated qubits via topologically protected edge states in a two-dimensional Hofstadter lattice. In this hybrid platform, the qubits a…
QISCIT: A validated concept inventory assessment for quantum information science
Kelley Durkin, Manshuo Lin, Michael H. Kolodrubetz +1
Quantum information science (QIS) is a critical interdisciplinary field that requires a well-educated workforce in the near future. Numerous researchers and educators have been act…
Effects of non-integrability in a non-Hermitian time crystal
Weihua Xie, Michael Kolodrubetz, Vadim Oganesyan +1
Time crystals are systems that spontaneously break time-translation symmetry, exhibiting repeating patterns in time. Recent work has shown that non-Hermitian Floquet systems can ho…
Topological anomalous Floquet photon pump
Manshuo Lin, Saeed Rahmanian Koshkaki, Mohsen Yarmohammadi +1
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 m…
Probing topological phases in a perturbed Kane-Mele model via RKKY interaction: Application to monolayer jacutingaite PtHgSe
Mohsen Yarmohammadi, Saeed Rahmanian Koshkaki, Jamal Berakdar +2
Quantum spin Hall insulators (QSHIs) are promising for spintronics, leveraging strong spin-orbit coupling for efficient spin manipulation via electrical and optical methods, with p…
Effect of noise on quantum circuit realization of non-Hermitian time crystals
Weihua Xie, Michael Kolodrubetz, Vadim Oganesyan
Non-Hermitian quantum dynamics lie in an intermediate regime between unitary Hamiltonian dynamics and trace-preserving non-unitary open quantum system dynamics. Given differences i…
Terahertz high-harmonic generation in gapped antiferromagnetic chains
Mohsen Yarmohammadi, Michael H. Kolodrubetz
The nonlinear dynamics of magnetization in antiferromagnets, resulting in high-frequency spin waves (high-order harmonics) as signal carriers, enable fast magnetic state switching…
Optimal Control and Glassiness in Quantum Sensing
Christopher I. Timms, Michael H. Kolodrubetz
Quantum systems are powerful detectors with wide-ranging applications from scanning probe microscopy of materials to biomedical imaging. Nitrogen vacancy (NV) centers in diamond, f…
Phases and phase transition in Grover's algorithm with systematic noise
Sasanka Dowarah, Chuanwei Zhang, Vedika Khemani +1
While limitations on quantum computation by Markovian environmental noise are well-understood in generality, their behavior for different quantum circuits and noise realizations ca…
