High resolution adaptive imaging of a single atom
J. D. Wong-Campos, K. G. Johnson, B. Neyenhuis +2
We report the optical imaging of a single atom with nanometer resolution using an adaptive optical alignment technique that is applicable to general optical microscopy. By decompos…
Sisyphus Thermalization of Photons in a Cavity-Coupled Double Quantum Dot
M. J. Gullans, J. Stehlik, Y. -Y. Liu +3
We investigate the non-classical states of light that emerge in a microwave resonator coupled to a periodically-driven electron in a nanowire double quantum dot (DQD). Under certai…
Tomography is necessary for universal entanglement detection with single-copy observables
Dawei Lu, Tao Xin, Nengkun Yu +7
Entanglement, one of the central mysteries of quantum mechanics, plays an essential role in numerous applications of quantum information theory. A natural question of both theoreti…
Quantum algorithm for systems of linear equations with exponentially improved dependence on precision
Andrew M. Childs, Robin Kothari, Rolando D. Somma
Harrow, Hassidim, and Lloyd showed that for a suitably specified matrix and -dimensional vector , there is a quantum algorithm that outputs a quantum s…
Grover search and the no-signaling principle
Ning Bao, Adam Bouland, Stephen P. Jordan
Two of the key properties of quantum physics are the no-signaling principle and the Grover search lower bound. That is, despite admitting stronger-than-classical correlations, quan…
Exact calculation of phonon effects on spin squeezing
D. Dylewsky, J. K. Freericks, M. L. Wall +2
Theoretical models of spins coupled to bosons provide a simple setting for studying a broad range of important phenomena in many-body physics, from virtually mediated interactions…
Kaleidoscope of quantum phases in a long-range interacting spin-1 chain
Zhe-Xuan Gong, Mohammad F. Maghrebi, Anzi Hu +4
Motivated by recent trapped-ion quantum simulation experiments, we carry out a comprehensive study of the phase diagram of a spin-1 chain with XXZ-type interactions that decay as $…
Continuous symmetry breaking and a new universality class in 1D long-range interacting quantum systems
Mohammad F. Maghrebi, Zhe-Xuan Gong, Alexey V. Gorshkov
Continuous symmetry breaking (CSB) in low-dimensional systems, forbidden by the Mermin-Wagner theorem for short-range interactions, may take place in the presence of slowly decayin…
Phase Retrieval Using Unitary 2-Designs
Shelby Kimmel, Yi-Kai Liu
We consider a variant of the phase retrieval problem, where vectors are replaced by unitary matrices, i.e., the unknown signal is a unitary matrix U, and the measurements consist o…
Anomalous broadening in driven dissipative Rydberg systems
E. A. Goldschmidt, T. Boulier, R. C. Brown +5
We observe interaction-induced broadening of the two-photon 5s-18s transition in 87Rb atoms trapped in a 3D optical lattice. The measured linewidth increases by nearly two orders o…
Renyi information from entropic effects in one higher dimension
Mohammad F. Maghrebi
Computing entanglement entropy and its cousins is often challenging even in the simplest continuum and lattice models, partly because such entropies depend nontrivially on all geom…
Detecting Consistency of Overlapping Quantum Marginals by Separability
Jianxin Chen, Zhengfeng Ji, Nengkun Yu +1
The quantum marginal problem asks whether a set of given density matrices are consistent, i.e., whether they can be the reduced density matrices of a global quantum state. Not many…
Serialized Quantum Error Correction Protocol for High-Bandwidth Quantum Repeaters
Andrew N. Glaudell, Edo Waks, Jacob M. Taylor
Advances in single photon creation, transmission, and detection suggest that sending quantum information over optical fibers may have losses low enough to be correctable using a qu…
Injection Locking of a Semiconductor Double Quantum Dot Micromaser
Y. -Y. Liu, J. Stehlik, M. J. Gullans +2
Emission linewidth is an important figure of merit for masers and lasers. We recently demonstrated a semiconductor double quantum dot (DQD) micromaser where photons are generated t…
Sample-optimal tomography of quantum states
Jeongwan Haah, Aram W. Harrow, Zhengfeng Ji +2
It is a fundamental problem to decide how many copies of an unknown mixed quantum state are necessary and sufficient to determine the state. Previously, it was known only that esti…
Causality and quantum criticality in long-range lattice models
Mohammad F. Maghrebi, Zhe-Xuan Gong, Michael Foss-Feig +1
Long-range quantum lattice systems often exhibit drastically different behavior than their short-range counterparts. In particular, because they do not satisfy the conditions for t…
Flight of a heavy particle nonlinearly coupled to a quantum bath
Mohammad F. Maghrebi, Matthias Krüger, Mehran Kardar
Fluctuation and dissipation are by-products of coupling to the `environment.' The Caldeira-Leggett model, a successful paradigm of quantum Brownian motion, views the environment as…
Framework for learning agents in quantum environments
Vedran Dunjko, Jacob M. Taylor, Hans J. Briegel
In this paper we provide a broad framework for describing learning agents in general quantum environments. We analyze the types of classically specified environments which allow fo…
Semiconductor double quantum dot micromaser
Y. -Y. Liu, J. Stehlik, C. Eichler +3
The coherent generation of light, from masers to lasers, relies upon the specific structure of the individual emitters that lead to gain. Devices operating as lasers in the few-emi…
Yang-Baxter operators need quantum entanglement to distinguish knots
Gorjan Alagic, Michael Jarret, Stephen P. Jordan
Any solution to the Yang-Baxter equation yields a family of representations of braid groups. Under certain conditions, identified by Turaev, the appropriately normalized trace of t…

Chiao-Hsuan Wang, Jacob M. Taylor
Motivated by understanding the emergence of thermodynamic restoring forces and oscillations, we develop a quantum-mechanical model of a bath of spins coupled to the elasticity of a…
Optical Control of Donor Spin Qubits in Silicon
M. J. Gullans, J. M. Taylor
We show how to achieve optical, spin-selective transitions from the ground state to excited orbital states of group-V donors (P, As, Sb, Bi) in silicon. We consider two approaches…
Optimal state discrimination and unstructured search in nonlinear quantum mechanics
Andrew M. Childs, Joshua Young
Nonlinear variants of quantum mechanics can solve tasks that are impossible in standard quantum theory, such as perfectly distinguishing nonorthogonal states. Here we derive the op…
Nonequilibrium many-body steady states via Keldysh formalism
Mohammad F. Maghrebi, Alexey V. Gorshkov
Many-body systems with both coherent dynamics and dissipation constitute a rich class of models which are nevertheless much less explored than their dissipationless counterparts. T…
