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…
Device-independent Randomness Expansion with Entangled Photons
Lynden K. Shalm, Yanbao Zhang, Joshua C. Bienfang +12
With the growing availability of experimental loophole-free Bell tests, it has become possible to implement a new class of device-independent random number generators whose output…
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…
Quantum Computing at the Frontiers of Biological Sciences
Prashant S. Emani, Jonathan Warrell, Alan Anticevic +15
The search for meaningful structure in biological data has relied on cutting-edge advances in computational technology and data science methods. However, challenges arise as we pus…
Quantum Gravity in the Lab: Teleportation by Size and Traversable Wormholes
Adam R. Brown, Hrant Gharibyan, Stefan Leichenauer +6
With the long-term goal of studying models of quantum gravity in the lab, we propose holographic teleportation protocols that can be readily executed in table-top experiments. Thes…
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…
Constant-sized correlations are sufficient to robustly self-test maximally entangled states with unbounded dimension
Honghao Fu
We show that for any prime odd integer , there exists a correlation of size that can robustly self-test a maximally entangled state of dimension , where is the…
Quantum Wasserstein Generative Adversarial Networks
Shouvanik Chakrabarti, Yiming Huang, Tongyang Li +2
The study of quantum generative models is well-motivated, not only because of its importance in quantum machine learning and quantum chemistry but also because of the perspective o…
Efficient simulation of random states and random unitaries
Gorjan Alagic, Christian Majenz, Alexander Russell
We consider the problem of efficiently simulating random quantum states and random unitary operators, in a manner which is convincing to unbounded adversaries with black-box oracle…
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.…

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…
Optimal fermion-to-qubit mapping via ternary trees with applications to reduced quantum states learning
Zhang Jiang, Amir Kalev, Wojciech Mruczkiewicz +1
We introduce a fermion-to-qubit mapping defined on ternary trees, where any single Majorana operator on an -mode fermionic system is mapped to a multi-qubit Pauli operator actin…
Auto-tuning of double dot devices in situ with machine learning
