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…
Synthetic gauge theories based on parametric excitations of trapped ions
O. BÄzÄvan, S. Saner, E. Tirrito +3
We present a detailed scheme for the analog quantum simulation of gauge theories in crystals of trapped ions, which exploits a more efficient hybrid encoding of the…
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 ~…
Generating arbitrary superpositions of nonclassical quantum harmonic oscillator states
S. Saner, O. BÄzÄvan, D. J. Webb +4
Full coherent control and generation of superpositions of the quantum harmonic oscillator are not only of fundamental interest but are crucial for applications in quantum simulatio…
Multipartite Entanglement for Multi-node Quantum Networks
E. M. Ainley, A. Agrawal, D. Main +5
Scaling the number of entangled nodes in a quantum network is a challenge with significant implications for quantum computing, clock synchronisation, secure communications, and qua…
