Quantum Nonlocal Games on Graph Ensembles
Joshua Tucker, Chris Weeks, Peter Drmota +11
Quantum entanglement is one of the most striking discoveries in all of science. This effect allows, for instance, two spatially separated agents to coordinate their actions, withou…
Efficient state estimation on quantum processors
Victor Gonzalez Avella, Abraham Vega Vargas, Tomas Merlo Vergara +6
We present two scalable and entanglement-free methods for estimating the collective state of an n-qubit quantum computer. The first method consists of a fixed set of five quantum c…
Real-Time Observation of Aharonov-Bohm Interference in a Lattice Gauge Theory on a Hybrid Qubit-Oscillator Quantum Computer
S. Saner, O. BÄzÄvan, D. J. Webb +5
Quantum simulations of lattice gauge theories (LGTs) with both dynamical matter and gauge fields provide a promising approach to studying strongly coupled problems beyond classical…
Multipartite Mixed-Species Entanglement over a Quantum Network
D. Main, P. Drmota, E. M. Ainley +9
We generate multipartite entangled states of two, three and four matter qubits, where the entanglement is distributed over macroscopic distances via a photonic network link. Trappe…
Towards quantum computing Feynman diagrams in hybrid qubit-oscillator devices
S. Varona, S. Saner, O. BÄzÄvan +3
We show that recent experiments in hybrid qubit-oscillator devices that measure the phase-space characteristic function of the oscillator via the qubit can be seen through the lens…
Experimental Quantum Advantage in the Odd-Cycle Game
P. Drmota, D. Main, E. M. Ainley +7
We report the first experimental demonstration of the odd-cycle game. We entangle two ions separated by ~2 m and the players use them to win the odd-cycle game with a probability ~…
