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…
Observation of Hopping and Blockade of Bosons in a Trapped Ion Spin Chain
S. Debnath, N. M. Linke, S. -T. Wang +4
The local phonon modes in a Coulomb crystal of trapped ions can represent a Hubbard system of coupled bosons. We selectively prepare single excitations at each site and observe fre…
Robust two-qubit gates in a linear ion crystal using a frequency-modulated driving force
Pak Hong Leung, Kevin A. Landsman, Caroline Figgatt +3
In an ion trap quantum computer, collective motional modes are used to entangle two or more qubits in order to execute multi-qubit logical gates. Any residual entanglement between…
Complete 3-Qubit Grover Search on a Programmable Quantum Computer
C. Figgatt, D. Maslov, K. A. Landsman +3
Searching large databases is an important problem with broad applications. The Grover search algorithm provides a powerful method for quantum computers to perform searches with a q…
Experimental Comparison of Two Quantum Computing Architectures
N. M. Linke, D. Maslov, M. Roetteler +5
We run a selection of algorithms on two state-of-the-art 5-qubit quantum computers that are based on different technology platforms. One is a publicly accessible superconducting tr…
