Exploring the Relaxation Landscape of a 2D Quantum Magnet on a 256-Qubit Processor
Tiago Mendes-Santos, Joseph Vovrosh, Sergi Julià-Farré +33
How quantum matter relaxes far from equilibrium is a central open problem in many-body physics, and one for which analog quantum simulators are well positioned to move from confirm…
Noise-aware emulation and cross-device validation of neutral atom analog quantum processing units
Constantin Dalyac, Sergi Julià-Farré, Lucas Leclerc +26
Analog quantum processors based on Rydberg atom arrays are a powerful platform for many-body quantum simulation, combinatorial optimization, and graph machine learning. As these de…
Benchmarking a machine-learning differential equations solver on a neutral-atom logical processor
Pauline Mathiot, Elio Garnaoui, Axel-Ugo Leriche +37
We report on a performance comparison between physical and logical computations on a prototypical machine-learning application: solving differential equations using quantum kernel…
One-to-one quantum simulation of a frustrated magnet with 256 qubits
Lucas Leclerc, Sergi Julià-Farré, Gabriel Silva Freitas +33
Analog quantum simulators offer a powerful microscopic probe of quantum many-body systems, yet have largely been benchmarked against model Hamiltonians rather than real materials.…
Financial Risk Management on a Neutral Atom Quantum Processor
Lucas Leclerc, Luis Ortiz-Guitierrez, Sebastian Grijalva +19
Machine Learning models capable of handling the large datasets collected in the financial world can often become black boxes expensive to run. The quantum computing paradigm sugges…
Quantum Feature Maps for Graph Machine Learning on a Neutral Atom Quantum Processor
Boris Albrecht, Constantin Dalyac, Lucas Leclerc +10
Using a quantum processor to embed and process classical data enables the generation of correlations between variables that are inefficient to represent through classical computati…
Long-lived non-classical correlations for scalable quantum repeaters at room temperature
Michael Zugenmaier, Karsten B. Dideriksen, Anders S. Sørensen +2
Heralded single-photon sources with on-demand readout are promising candidates for quantum repeaters enabling long-distance quantum communication. The need for scalability of such…
Non-classical correlations between a C-band telecom photon and a stored spin-wave
Pau Farrera, Nicolas Maring, Boris Albrecht +2
Future ground-based quantum information networks will likely use single photons transmitted through optical fibers to entangle individual network nodes. To extend communication dis…
Generation of single photons with highly tunable wave shape from a cold atomic quantum memory
Pau Farrera, Georg Heinze, Boris Albrecht +5
We report on a single photon source with highly tunable photon shape based on a cold ensemble of Rubidium atoms. We follow the DLCZ scheme to implement an emissive quantum memory,…
Controlled rephasing of single collective spin excitations in a cold atomic quantum memory
Boris Albrecht, Pau Farrera, Georg Heinze +2
We demonstrate active control of inhomogeneous dephasing and rephasing for single collective atomic spin excitations (spin-waves) created by spontaneous Raman scattering in a quant…
A Waveguide Frequency Converter Connecting Rubidium Based Quantum Memories to the Telecom C-Band
Boris Albrecht, Pau Farrera, Xavier Fernandez-Gonzalvo +2
The ability to coherently convert the frequency and temporal waveform of single and entangled photons will be crucial to interconnect the various elements of future quantum informa…
Quantum frequency conversion of quantum memory compatible photons to telecommunication wavelengths
Xavier Fernandez-Gonzalvo, Giacomo Corrielli, Boris Albrecht +3
We report an experiment demonstrating quantum frequency conversion of weak light pulses compatible with atomic quantum memories to telecommunication wavelengths. We use a PPLN nonl…
