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…

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…

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 ~…
