Sampling Noise and Optimized Measurement Distribution in Imaginary-Time Quantum Dynamics Simulations

Feng Zhang, Niladri Gomes, Joshua Aftergood +3

Variational quantum dynamics simulations (VQDS) provide a promising route to simulate real- and imaginary-time quantum dynamics on noisy intermediate-scale quantum devices using fi…

Measurement and feedback-driven adaptive dynamics in the classical and quantum kicked top

Mahaveer Prasad, Ahana Chakraborty, Thomas Iadecola +4

In classical dynamical systems, stochastic feedback can stabilize otherwise unstable periodic orbits, giving rise to distinct controlled and uncontrolled phases as the rate of cont…

Dissipative Preparation of Correlated Quantum States in Dipolar Rydberg Arrays

Mingsheng Tian, Zhen Bi, Thomas Iadecola +1

Preparing correlated quantum states is essential for emerging technologies, but remains challenging in many-body systems. Here we propose a dissipative protocol that engineers nonr…

Post-selected Criticality in Measurement-induced Phase Transitions

Dolly Nambi, Kabir Khanna, Andrew Allocca +4

Information-theoretic phase transitions, such as the measurement-induced phase transition (MIPT), characterize the robustness of quantum dynamics to local monitoring and are natura…

Quantum Cellular Automata on a Dual-Species Rydberg Processor

Ryan White, Vikram Ramesh, Alexander Impertro +6

As quantum devices scale to larger and larger sizes, a significant challenge emerges in scaling their coherent controls accordingly. Quantum cellular automata (QCAs) constitute a p…
