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…
Fundamental limitations on photoisomerization from thermodynamic resource theories
Nicole Yunger Halpern, David T. Limmer
Small, out-of-equilibrium, and quantum systems defy simple thermodynamic expressions. Such systems are exemplified by molecular switches, which exchange heat with a bath. These mol…
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…
Pulse analysis by delayed absorption from a coherently excited atom
Jan Marcus Dahlström, Stefan Pabst, Eva Lindroth
In this tutorial we provide a short review of attosecond pulse characterization techniques and a pedagogical account of a recently proposed method called Pulse Analysis by Delayed…
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…
Exploring universal and non-universal regimes of trimers from three-body interactions in one-dimensional lattices
Arthur Christianen, John Sous
We investigate the formation of trimers in an infinite one-dimensional lattice model of hard-core particles with single-particle hopping and and nearest-neighbour two-body …
Shattered Time: Can a Dissipative Time Crystal Survive Many-Body Correlations?
Kristopher Tucker, Bihui Zhu, Robert J. Lewis-Swan +4
We investigate the emergence of a time crystal in a driven-dissipative many-body spin array. In this system the interplay between incoherent spin pumping and collective emission st…
Simultaneous Broadband Vector Magnetometry Using Solid-State Spins
Jennifer M. Schloss, John F. Barry, Matthew J. Turner +1
We demonstrate a vector magnetometer that simultaneously measures all Cartesian components of a dynamic magnetic field using an ensemble of nitrogen-vacancy (NV) centers in a singl…
Geometric phase magnetometry using a solid-state spin
Keigo Arai, Junghyun Lee, Chinmay Belthangady +3
Magnetometry is a powerful technique for the non-invasive study of biological and physical systems. A key challenge lies in the simultaneous optimization of magnetic field sensitiv…
Effective spin-spin interactions in bilayers of Rydberg atoms and polar molecules
Elena Kuznetsova, Seth T. Rittenhouse, I. I. Beterov +3
We show that indirect spin-spin interactions between effective spin-1/2 systems can be realized in two parallel 1D optical lattices loaded with polar molecules and/or Rydberg atoms…
Light, the universe, and everything -- 12 Herculean tasks for quantum cowboys and black diamond skiers
Girish Agarwal, Roland Allen, Iva Bezdekova +29
The Winter Colloquium on the Physics of Quantum Electronics (PQE) has been a seminal force in quantum optics and related areas since 1971. It is rather mindboggling to recognize ho…
Ultralong Dephasing Times in Solid-State Spin Ensembles via Quantum Control
Erik Bauch, Connor A. Hart, Jennifer M. Schloss +5
Quantum spin dephasing is caused by inhomogeneous coupling to the environment, with resulting limits to the measurement time and precision of spin-based sensors. The effects of spi…
Sensing coherent dynamics of electronic spin clusters in solids
Emma L. Rosenfeld, Linh M. Pham, Mikhail D. Lukin +1
We present experimental observations and a study of quantum dynamics of strongly interacting electronic spins, at room temperature in the solid state. In a diamond substrate, a sin…
