Error Correction in a Distributed Quantum Computer
E. M. Ainley, A. Agrawal, T. Araki +12
Building fault-tolerant quantum computers with large numbers of logical qubits requires both scalable hardware architectures and error-correcting codes that make efficient use of p…
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…
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…
Recoil-induced errors and their correction in photon-mediated entanglement between atom qubits
Jan Apolín, David P. Nadlinger
Photonically-interconnected matter qubit systems have wide-ranging applications across quantum science and technology, with entanglement between distant qubits serving as a univers…
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…
Distributed Quantum Computing across an Optical Network Link
D. Main, P. Drmota, D. P. Nadlinger +6
Distributed quantum computing (DQC) combines the computing power of multiple networked quantum processing modules, enabling the execution of large quantum circuits without compromi…
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 ~…
Squeezing, trisqueezing, and quadsqueezing in a spin-oscillator system
O. Băzăvan, S. Saner, D. J. Webb +7
Quantum harmonic oscillators model a wide variety of phenomena ranging from electromagnetic fields to vibrations of atoms in molecules. Their excitations can be represented by boso…
Robust and fast microwave-driven quantum logic for trapped-ion qubits
M. A. Weber, M. F. Gely, R. K. Hanley +5
Microwave-driven logic is a promising alternative to laser control in scaling trapped-ion based quantum processors. However, such electronic gates have yet to match the speed offer…
Low Cross-Talk Optical Addressing of Trapped-Ion Qubits Using a Novel Integrated Photonic Chip
A. S. Sotirova, B. Sun, J. D. Leppard +10
Individual optical addressing in chains of trapped atomic ions requires generation of many small, closely spaced beams with low cross-talk. Furthermore, implementing parallel opera…
