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…
Rapid all-optical loading of trapped ions using a miniaturised atom source
Lorenzo Versini, Tim F. Wohlers-Reichel, Catherine E. J. Challoner +8
We characterise an efficient optically-heated neutral atom source for ion trapping. We observe loading rates of up to with heating powers below $85\,\mathr…
Quantum-Assisted Graph Domination Games
C. Weeks, P. Strange, P. Drmota +1
We study quantum advantage in the 1-step graph domination game on cycle graphs numerically, analytically and through the use of Noisy intermediate scale quantum (NISQ) processors.…
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…
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…
Breaking the entangling gate speed limit for trapped-ion qubits using a phase-stable standing wave
S. Saner, O. Băzăvan, M. Minder +6
All laser-driven entangling operations for trapped-ion qubits have hitherto been performed without control of the optical phase of the light field, which precludes independent tuni…
Verifiable blind quantum computing with trapped ions and single photons
P. Drmota, D. P. Nadlinger, D. Main +9
We report the first hybrid matter-photon implementation of verifiable blind quantum computing. We use a trapped-ion quantum server and a client-side photonic detection system netwo…
Robust Quantum Memory in a Trapped-Ion Quantum Network Node
P. Drmota, D. Main, D. P. Nadlinger +8
We integrate a long-lived memory qubit into a mixed-species trapped-ion quantum network node. Ion-photon entanglement first generated with a network qubit in Sr-88 is transferred t…
A quantum network of entangled optical atomic clocks
B. C. Nichol, R. Srinivas, D. P. Nadlinger +5
Optical atomic clocks are our most precise tools to measure time and frequency. They enable precision frequency comparisons between atoms in separate locations to probe the space-t…
Experimental quantum key distribution certified by Bell's theorem
D. P. Nadlinger, P. Drmota, B. C. Nichol +12
Cryptographic key exchange protocols traditionally rely on computational conjectures such as the hardness of prime factorisation to provide security against eavesdropping attacks.…
Micromotion minimisation by synchronous detection of parametrically excited motion
D. P. Nadlinger, P. Drmota, D. Main +6
Precise control of charged particles in radio-frequency (Paul) traps requires minimising excess micromotion induced by stray electric fields. We present a method to detect and comp…
High-rate, high-fidelity entanglement of qubits across an elementary quantum network
L J Stephenson, D P Nadlinger, B C Nichol +7
We demonstrate remote entanglement of trapped-ion qubits via a quantum-optical fiber link with fidelity and rate approaching those of local operations. Two Sr qubi…
