Measuring the Renyi entropy of a two-site Fermi-Hubbard model on a trapped ion quantum computer
Norbert M. Linke, Sonika Johri, Caroline Figgatt +3
The efficient simulation of correlated quantum systems is the most promising near-term application of quantum computers. Here, we present a measurement of the second Renyi entropy…
Dark state optical lattice with sub-wavelength spatial structure
Yang Wang, Sarthak Subhankar, Przemyslaw Bienias +7
We report on the experimental realization of a conservative optical lattice for cold atoms with sub-wavelength spatial structure. The potential is based on the nonlinear optical re…
Holographic Complexity of Einstein-Maxwell-Dilaton Gravity
Brian Swingle, Yixu Wang
We study the holographic complexity of Einstein-Maxwell-Dilaton gravity using the recently proposed "complexity = volume" and "complexity = action" dualities. The model we consider…

Andrew M. Childs, Dmitri Maslov, Yunseong Nam +2
With quantum computers of significant size now on the horizon, we should understand how to best exploit their initially limited abilities. To this end, we aim to identify a practic…
Maximally Entangled State and Bell's Inequality in Qubits
Su-Kuan Chu, Chen-Te Ma, Rong-Xin Miao +1
A maximally entangled state is a quantum state which has maximum von Neumann entropy for each bipartition. Through proposing a new method to classify quantum states by using concur…
Probing electron-phonon interactions in the charge-photon dynamics of cavity-coupled double quantum dots
M. J. Gullans, J. M. Taylor, J. R. Petta
Electron-phonon coupling is known to play an important role in the charge dynamics of semiconductor quantum dots. Here we explore its role in the combined charge-photon dynamics of…
High-fidelity quantum gates in Si/SiGe double quantum dots
Maximilian Russ, D. M. Zajac, A. J. Sigillito +4
Motivated by recent experiments of Zajac et al. [arXiv:1708.03530], we theoretically describe high-fidelity two-qubit gates using the exchange interaction between the spins in neig…

Pedro C. S. Costa, Stephen Jordan, Aaron Ostrander
We present a quantum algorithm for simulating the wave equation under Dirichlet and Neumann boundary conditions. The algorithm uses Hamiltonian simulation and quantum linear system…
Faster Quantum Algorithm to simulate Fermionic Quantum Field Theory
Ali Hamed Moosavian, Stephen Jordan
In quantum algorithms discovered so far for simulating scattering processes in quantum field theories, state preparation is the slowest step. We present a new algorithm for prepari…
Pseudorandom States, Non-Cloning Theorems and Quantum Money
Zhengfeng Ji, Yi-Kai Liu, Fang Song
We propose the concept of pseudorandom states and study their constructions, properties, and applications. Under the assumption that quantum-secure one-way functions exist, we pres…

Quantum computers can offer dramatic improvements over classical devices for data analysis tasks such as prediction and classification. However, less is known about the advantages…
Bell's Inequality, Generalized Concurrence and Entanglement in Qubits
Po-Yao Chang, Su-Kuan Chu, Chen-Te Ma
It is well known that the maximal violation of the Bell's inequality for a two-qubit system is related to the entanglement formation in terms of a concurrence. However, a generaliz…
