Entanglement Swapping with Integrated Narrowband Photon Sources for Quantum Repeaters
Mingsong Wu, Leili Esmaeilifar, Rui Ning Wang +3
Promising implementations of first generation quantum repeaters are predicted to require atomic-based quantum memory systems interfaced with photonic sources. Integrated photonics…
Integrated Telecom Wavelength Heralded Single-Photon Source based on GHz gated detectors
Maria Ana Pereira, Mingsong Wu, Arslan Sajid Raja +5
We introduce a simple and flexible concept for a heralded -- spectrally pure -- single photon source. The scheme uses a probabilistic photon pair source pumped with a CW laser, whe…
Towards heralded distribution of polarization entanglement
Francis Marcellino, Patrik Caspar, Tiff Brydges +2
Distributing entangled states over potentially long distances provides a key resource for many protocols in quantum communication and quantum cryptography. Ideally, this should be…
GHz detection rates and dynamic photon-number resolution with superconducting nanowire arrays
Giovanni V. Resta, Lorenzo Stasi, Matthieu Perrenoud +5
Superconducting-nanowire single-photon detectors (SNSPDs) have enabled the realization of several quantum optics technologies thanks to their high detection efficiency, low dark-co…
Enhanced heralded single-photon source with a photon-number-resolving parallel superconducting nanowire single-photon detector
Lorenzo Stasi, Patrik Caspar, Tiff Brydges +3
Heralded single-photon sources (HSPS) intrinsically suffer from multiphoton emission, leading to a trade-off between the source's quality and the heralding rate. A solution to this…
An Integrated Photon-Pair Source with Monolithic Piezoelectric Frequency Tunability
Tiff Brydges, Arslan S. Raja, Angelo Gelmini +9
This work demonstrates the capabilities of an entangled photon-pair source at telecom wavelengths, based on a photonic integrated SiN microresonator with monolithically int…
Controlling long ion strings for quantum simulation and precision measurements
Florian Kranzl, Manoj K. Joshi, Christine Maier +4
Scaling a trapped-ion based quantum simulator to a large number of ions creates a fully-controllable quantum system that becomes inaccessible to numerical methods. When highly anis…
Polarization-gradient cooling of 1D and 2D ion Coulomb crystals
M. K. Joshi, A. Fabre, C. Maier +5
We present experiments on polarization gradient cooling of Ca multi-ion Coulomb crystals in a linear Paul trap. Polarization gradient cooling of the collective modes of motion…
Quantum information scrambling in a trapped-ion quantum simulator with tunable range interactions
Manoj K. Joshi, Andreas Elben, Benoît Vermersch +5
In ergodic many-body quantum systems, locally encoded quantum information becomes, in the course of time evolution, inaccessible to local measurements. This concept of "scrambling"…
Cross-Platform Verification of Intermediate Scale Quantum Devices
Andreas Elben, Benoît Vermersch, Rick van Bijnen +7
We describe a protocol for cross-platform verification of quantum simulators and quantum computers. We show how to measure directly the overlap an…
Self-Verifying Variational Quantum Simulation of the Lattice Schwinger Model
Christian Kokail, Christine Maier, Rick van Bijnen +8
Hybrid classical-quantum algorithms aim at variationally solving optimisation problems, using a feedback loop between a classical computer and a quantum co-processor, while benefit…
Environment-assisted quantum transport in a 10-qubit network
Christine Maier, Tiff Brydges, Petar Jurcevic +6
The way in which energy is transported through an interacting system governs fundamental properties in many areas of physics, chemistry, and biology. Remarkably, environmental nois…
Probing entanglement entropy via randomized measurements
Tiff Brydges, Andreas Elben, Petar Jurcevic +6
Entanglement is the key feature of many-body quantum systems, and the development of new tools to probe it in the laboratory is an outstanding challenge. Measuring the entropy of d…
Direct observation of dynamical quantum phase transitions in an interacting many-body system
P. Jurcevic, H. Shen, P. Hauke +7
Dynamical quantum phase transitions (DQPTs) extend the concept of phase transitions and thus universality to the non-equilibrium regime. In this letter, we investigate DQPTs in a s…
