Emergent SU(2) dynamics and perfect quantum many-body scars
Soonwon Choi, Christopher J. Turner, Hannes Pichler +6
Motivated by recent experimental observations of coherent many-body revivals in a constrained Rydberg atom chain, we construct a weak quasi-local deformation of the Rydberg blockad…
Quantum Virtual Cooling
Jordan Cotler, Soonwon Choi, Alexander Lukin +10
We propose a quantum information based scheme to reduce the temperature of quantum many-body systems, and access regimes beyond the current capability of conventional cooling techn…
Quantum Approximate Optimization Algorithm: Performance, Mechanism, and Implementation on Near-Term Devices
Leo Zhou, Sheng-Tao Wang, Soonwon Choi +2
The Quantum Approximate Optimization Algorithm (QAOA) is a hybrid quantum-classical variational algorithm designed to tackle combinatorial optimization problems. Despite its promis…
Computational complexity of the Rydberg blockade in two dimensions
Hannes Pichler, Sheng-Tao Wang, Leo Zhou +2
We discuss the computational complexity of finding the ground state of the two-dimensional array of quantum bits that interact via strong van der Waals interactions. Specifically,…
Quantum Kibble-Zurek mechanism and critical dynamics on a programmable Rydberg simulator
Alexander Keesling, Ahmed Omran, Harry Levine +12
Quantum phase transitions (QPTs) involve transformations between different states of matter that are driven by quantum fluctuations. These fluctuations play a dominant role in the…
Quantum Optimization for Maximum Independent Set Using Rydberg Atom Arrays
Hannes Pichler, Sheng-Tao Wang, Leo Zhou +2
We describe and analyze an architecture for quantum optimization to solve maximum independent set (MIS) problems using neutral atom arrays trapped in optical tweezers. Optimizing i…
Numerical study of the chiral quantum phase transition in one spatial dimension
Rhine Samajdar, Soonwon Choi, Hannes Pichler +2
Recent experiments on a one-dimensional chain of trapped alkali atoms [arXiv:1707.04344] have observed a quantum transition associated with the onset of period-3 ordering of pumped…
Periodic orbits, entanglement and quantum many-body scars in constrained models: matrix product state approach
Wen Wei Ho, Soonwon Choi, Hannes Pichler +1
We analyze quantum dynamics of strongly interacting, kinetically constrained many-body systems. Motivated by recent experiments demonstrating surprising long-lived, periodic reviva…
