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…
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…
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…
