Provable bounds for noise-free expectation values computed from noisy samples
Samantha V. Barron, Daniel J. Egger, Elijah Pelofske +4
In this paper, we explore the impact of noise on quantum computing, particularly focusing on the challenges when sampling bit strings from noisy quantum computers as well as the im…
Strong hole-photon coupling in planar Ge for probing charge degree and strongly-correlated states
Franco De Palma, Fabian Oppliger, Wonjin Jang +7
Semiconductor quantum dots (QDs) in planar germanium (Ge) heterostructures have emerged as front-runners for future hole-based quantum processors. Here, we present strong coupling…
Optomechanical realization of the bosonic Kitaev-Majorana chain
Jesse J. Slim, Clara C. Wanjura, Matteo Brunelli +3
The fermionic Kitaev chain is a canonical model featuring topological Majorana zero modes. We report the experimental realization of its bosonic analogue in a nano-optomechanical n…
QDistRnd: A GAP package for computing the distance of quantum error-correcting codes
Leonid P. Pryadko, Vadim A. Shabashov, Valerii K. Kozin
The GAP package QDistRnd implements a probabilistic algorithm for finding the minimum distance of a quantum low-density parity-check code linear over a finite field GF(q). At each…
Enhanced repetition codes for the cross-platform comparison of progress towards fault-tolerance
Milan Liepelt, Tommaso Peduzzi, James R. Wootton
Achieving fault-tolerance will require a strong relationship between the hardware and the protocols used. Different approaches will therefore naturally have tailored proof-of-princ…
Probe thermometry with continuous measurements
Julia Boeyens, Björn Annby-Andersson, Pharnam Bakhshinezhad +5
Temperature estimation plays a vital role across natural sciences. A standard approach is provided by probe thermometry, where a probe is brought into contact with the sample and e…
Shallow Silicon Vacancy Centers with lifetime-limited optical linewidths in Diamond Nanostructures
Josh A. Zuber, Minghao Li, Marcel. li Grimau Puigibert +4
The negatively charged silicon vacancy center (SiV) in diamond is a promising, yet underexplored candidate for single-spin quantum sensing at sub-kelvin temperatures and tesla-…
Enhanced Electron Spin Coherence in a GaAs Quantum Emitter
Giang N. Nguyen, Clemens Spinnler, Mark R. Hogg +10
A spin-photon interface should operate with both coherent photons and a coherent spin to enable cluster-state generation and entanglement distribution. In high-quality devices, sel…
Macroscopic quantum synchronization effects
Tobias Nadolny, Christoph Bruder
We theoretically describe macroscopic quantum synchronization effects occurring in a network of all-to-all coupled quantum limit-cycle oscillators. The coupling causes a transition…
Improving Transmon Qudit Measurement on IBM Quantum Hardware
Tobias Kehrer, Tobias Nadolny, Christoph Bruder
The Hilbert space of a physical qubit typically features more than two energy levels. Using states outside the qubit subspace can provide advantages in quantum computation. To bene…
Electromagnetically Induced Transparency and Optical Pumping in the Hyperfine Paschen-Back Regime
Roberto Mottola, Gianni Buser, Philipp Treutlein
We report spectroscopy experiments of rubidium vapor in a high magnetic field under conditions of electromagnetically induced transparency (EIT) and optical pumping. The 1.1 T stat…
Optical Memory in a Microfabricated Rubidium Vapor Cell
Roberto Mottola, Gianni Buser, Philipp Treutlein
Scalability presents a central platform challenge for the components of current quantum network implementations that can be addressed by microfabrication techniques. We demonstrate…
Error-tolerant quantum convolutional neural networks for symmetry-protected topological phases
Petr Zapletal, Nathan A. McMahon, Michael J. Hartmann
The analysis of noisy quantum states prepared on current quantum computers is getting beyond the capabilities of classical computing. Quantum neural networks based on parametrized…
Mapping out phase diagrams with generative classifiers
Julian Arnold, Frank Schäfer, Alan Edelman +1
One of the central tasks in many-body physics is the determination of phase diagrams. However, mapping out a phase diagram generally requires a great deal of human intuition and un…
Quantum Fluctuation Theorem for Arbitrary Measurement and Feedback Schemes
Kacper Prech, Patrick P. Potts
Fluctuation theorems and the second law of thermodynamics are powerful relations constraining the behavior of out-of-equilibrium systems. While there exist generalizations of these…
High-fidelity two-qubit gates of hybrid superconducting-semiconducting singlet-triplet qubits
Maria Spethmann, Stefano Bosco, Andrea Hofmann +2
Hybrid systems comprising superconducting and semiconducting materials are promising architectures for quantum computing. Superconductors induce long-range interactions between the…
Performance Bounds for Quantum Feedback Control
Flemming Holtorf, Frank Schäfer, Julian Arnold +2
The limits of quantum feedback control have immediate consequences for quantum information science at large, yet remain largely unexplored. Here, we combine quantum filtering theor…
The Wave-Particle Duality in a Quantum Heat Engine
Marcelo Janovitch, Matteo Brunelli, Patrick P. Potts
According to the wave-particle duality (WPD), quantum systems show both particle- and wave-like behavior, and cannot be described using only one of these classical concepts. Identi…
Current fluctuations in open quantum systems: Bridging the gap between quantum continuous measurements and full counting statistics
Gabriel T. Landi, Michael J. Kewming, Mark T. Mitchison +1
Continuously measured quantum systems are characterized by an output current, in the form of a stochastic and correlated time series which conveys crucial information about the und…
Geometric Phase in Quantum Synchronization
Aaron Daniel, Christoph Bruder, Martin Koppenhöfer
We consider a quantum limit-cycle oscillator implemented in a spin system whose quantization axis is slowly rotated. Using a kinematic approach to define geometric phases in nonuni…
The non-reciprocal Dicke model
Ezequiel I. Rodríguez Chiacchio, Andreas Nunnenkamp, Matteo Brunelli
We investigate the physics of an open two-component Dicke model, where the light field mediates non-reciprocal interactions between two spin species. We show that the model, which…
