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…
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…
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…
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…
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…
