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…
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…
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…
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…
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…
A Quantum Model for Entropic Springs
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…
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…
Simulating the Haldane Phase in Trapped Ion Spins Using Optical Fields
I. Cohen, P. Richerme, Z. -X. Gong +2
We propose to experimentally explore the Haldane phase in spin-one XXZ antiferromagnetic chains using trapped ions. We show how to adiabatically prepare the ground states of the Ha…
Coulomb bound states of strongly interacting photons
M. F. Maghrebi, M. J. Gullans, P. Bienias +6
We show that two photons coupled to Rydberg states via electromagnetically induced transparency can interact via an effective Coulomb potential. This interaction gives rise to a co…
Robust Calibration of a Universal Single-Qubit Gate-Set via Robust Phase Estimation
Shelby Kimmel, Guang Hao Low, Theodore J. Yoder
An important step in building a quantum computer is calibrating experimentally implemented quantum gates to produce operations that are close to ideal unitaries. The calibration st…
