Observation of Domain Wall Confinement and Dynamics in a Quantum Simulator
W. L. Tan, P. Becker, F. Liu +11
Confinement is a ubiquitous mechanism in nature, whereby particles feel an attractive force that increases without bound as they separate. A prominent example is color confinement…
Destructive Error Interference in Product-Formula Lattice Simulation
Minh C. Tran, Su-Kuan Chu, Yuan Su +2
Quantum computers can efficiently simulate the dynamics of quantum systems. In this paper, we study the cost of digitally simulating the dynamics of several physically relevant sys…
Beyond Spontaneous Emission: Giant Atom Bounded in Continuum
Shangjie Guo, Yidan Wang, Thomas Purdy +1
The quantum coupling of individual superconducting qubits to microwave photons leads to remarkable experimental opportunities. Here we consider the phononic case where the qubit is…
Quantum Simulators: Architectures and Opportunities
Ehud Altman, Kenneth R. Brown, Giuseppe Carleo +34
Quantum simulators are a promising technology on the spectrum of quantum devices from specialized quantum experiments to universal quantum computers. These quantum devices utilize…
A Theory of Trotter Error
Andrew M. Childs, Yuan Su, Minh C. Tran +2
The Lie-Trotter formula, together with its higher-order generalizations, provides a direct approach to decomposing the exponential of a sum of operators. Despite significant effort…
Programmable Quantum Simulations of Spin Systems with Trapped Ions
C. Monroe, W. C. Campbell, L. -M. Duan +10
Laser-cooled and trapped atomic ions form an ideal standard for the simulation of interacting quantum spin models. Effective spins are represented by appropriate internal energy le…
Quantum Computer Systems for Scientific Discovery
Yuri Alexeev, Dave Bacon, Kenneth R. Brown +21
The great promise of quantum computers comes with the dual challenges of building them and finding their useful applications. We argue that these two challenges should be considere…
Counting statistics of microwave photons in circuit QED
Konstantin N. Nesterov, Ivan V. Pechenezhskiy, Maxim G. Vavilov
In superconducting circuit architectures for quantum computing, microwave resonators are often used both to isolate qubits from the electromagnetic environment and to facilitate qu…
Operational Resource Theory of Nonclassicality via Quantum Metrology
Wenchao Ge, Kurt Jacobs, Saeed Asiri +2
The nonclassical properties of quantum states are of tremendous interest due to their potential applications in future technologies. It has recently been realized that the concept…
Atom-Field Interaction: From Vacuum Fluctuations to Quantum Radiation and Quantum Dissipation / Radiation Reaction
Jen-Tsung Hsiang, B. L. Hu
In this paper we dwell on three issues: 1) revisit the relation between vacuum fluctuations and radiation reaction in atom-field interactions, which began in the 70s and settled in…
On the nature of the non-equilibrium phase transition in the non-Markovian driven Dicke model
Rex Lundgren, Alexey V. Gorshkov, Mohammad F. Maghrebi
The Dicke model famously exhibits a phase transition to a superradiant phase with a macroscopic population of photons and is realized in multiple settings in open quantum systems.…
Quantum Brownian Motion of a particle from Casimir-Polder Interactions
Kanupriya Sinha, Yigit Subasi
We study the fluctuation-induced dissipative dynamics of the quantized center of mass motion of a polarizable dielectric particle trapped near a surface. The particle's center of m…
Quantum Simulation of Hyperbolic Space with Circuit Quantum Electrodynamics: From Graphs to Geometry
Igor Boettcher, Przemyslaw Bienias, Ron Belyansky +2
We show how quantum many-body systems on hyperbolic lattices with nearest-neighbor hopping and local interactions can be mapped onto quantum field theories in continuous negatively…
Back-action evading impulse measurement with mechanical quantum sensors
Sohitri Ghosh, Daniel Carney, Peter Shawhan +1
The quantum measurement of any observable naturally leads to noise added by the act of measurement. Approaches to evade or reduce this noise can lead to substantial improvements in…

Jen-Tsung Hsiang, Bei-Lok Hu
This paper presents a nonperturbative treatment of strong-coupling induced effects in atom-field systems which cannot be seen in traditional perturbative treatments invoking compro…
Auto-tuning of double dot devices in situ with machine learning
Justyna P. Zwolak, Thomas McJunkin, Sandesh S. Kalantre +7
The current practice of manually tuning quantum dots (QDs) for qubit operation is a relatively time-consuming procedure that is inherently impractical for scaling up and applicatio…
Fluctuations in extractable work bound the charging power of quantum batteries
Luis Pedro García-Pintos, Alioscia Hamma, Adolfo del Campo
We study the connection between the charging power of quantum batteries and the fluctuations of the extractable work. We prove that in order to have a non-zero rate of change of th…
