Zeno dynamics in quantum open systems
2015 · Scientific Reports
Quantum Zeno effect shows that frequent observations can slow down or even stop the unitary time evolution of an unstable quantum system. This effect can also be regarded as a physical consequence of the statistical …

Nonlocal advantage of quantum coherence in high-dimensional states
2018 · Physical Review A
By local measurements on party $A$ of a system $\mathit{AB}$ and classical communication between its two parties, one can achieve a nonlocal advantage of quantum coherence (NAQC) on party $B$. For the ${l}_{1}$ norm of …

Strongly correlated quantum walks with a 12-qubit superconducting processor
2019 · Science
Quantum walks are the quantum analogs of classical random walks, which allow for the simulation of large-scale quantum many-body systems and the realization of universal quantum computation without time-dependent control. We experimentally demonstrate quantum walks …

A Probabilistic Imaginary Time Evolution Algorithm Based on Non-unitary Quantum Circuit
2022 · arXiv (Cornell University)
Imaginary time evolution is a powerful tool applied in quantum physics, while existing classical algorithms for simulating imaginary time evolution suffer high computational complexity as the quantum systems become larger and more complex. In this …

Multimode Purcell filter for superconducting-qubit reset and readout with intrinsic Purcell protection
2026 · Physical Review Applied
Efficient qubit reset and leakage reduction are essential for scalable superconducting quantum computing, particularly in the context of quantum error correction. However, such operations often require additional on-chip components. Here, we propose and experimentally demonstrate …

Markov Gap and Bound Entanglement in Haar Random State
2025 · arXiv (Cornell University)
Bound entanglement refers to entangled states that cannot be distilled into maximally entangled states and therefore cannot directly be used in many quantum information processing protocols. We identify a relationship between bound entanglement and the …
