Factoring an integer with three oscillators and a qubit
Lukas Brenner, Libor Caha, Xavier Coiteux-Roy +1
A common starting point of traditional quantum algorithm design is the notion of a universal quantum computer with a scalable number of qubits. This convenient abstraction mirrors…
Variational Quantum Generative Modeling by Sampling Expectation Values of Tunable Observables
Kevin Shen, Andrii Kurkin, Adrián Pérez-Salinas +3
Expectation Value Samplers (EVSs) are quantum generative models that can learn high-dimensional continuous distributions by measuring the expectation values of parameterized quantu…
Solving one-body ensemble N-representability problems with spin
Julia Liebert, Federico Castillo, Jean-Philippe Labbé +2
The Pauli exclusion principle is fundamental to understanding electronic quantum systems. It namely constrains the expected occupancies of orbitals according to $0 \leq…
Quantum Optics Applications of Hexagonal Boron Nitride Defects
Aslı Çakan, Chanaprom Cholsuk, Angus Gale +6
Hexagonal boron nitride (hBN) has emerged as a compelling platform for both classical and quantum technologies. In particular, the past decade has witnessed a surge of novel ideas…
Stabilizer disentangling of conformal field theories
Martina Frau, Poetri Sonya Tarabunga, Mario Collura +2
Understanding how entanglement can be reduced through simple operations is crucial for both classical and quantum algorithms. We investigate the entanglement properties of lattice…
A nonstabilizerness monotone from stabilizerness asymmetry
Poetri Sonya Tarabunga, Martina Frau, Tobias Haug +2
We introduce a nonstabilizerness monotone which we name basis-minimised stabilizerness asymmetry (BMSA). It is based on the notion of -asymmetry, a measure of how much a certain…
Fast entangling gates for Rydberg atoms via resonant dipole-dipole interaction
Giuliano Giudici, Stefano Veroni, Giacomo Giudice +2
The advent of digital neutral-atom quantum computers relies on the development of fast and robust protocols for high-fidelity quantum operations. In this work, we introduce a novel…
The complexity of Gottesman-Kitaev-Preskill states
Lukas Brenner, Libor Caha, Xavier Coiteux-Roy +1
We initiate the study of state complexity for continuous-variable quantum systems. Concretely, we consider a setup with bosonic modes and auxiliary qubits, where available operatio…
The product structure of MPS-under-permutations
Marta Florido-Llinàs, Álvaro M. Alhambra, Rahul Trivedi +3
Tensor network methods have proved to be highly effective in addressing a wide variety of physical scenarios, including those lacking an intrinsic one-dimensional geometry. In such…
Quantum Many-Body Scars beyond the PXP model in Rydberg simulators
Aron Kerschbaumer, Marko Ljubotina, Maksym Serbyn +1
Persistent revivals recently observed in Rydberg atom simulators have challenged our understanding of thermalization and attracted much interest to the concept of quantum many-body…
Equivalence checking of quantum circuits via intermediary matrix product operator
Aaron Sander, Lukas Burgholzer, Robert Wille
As quantum computing advances, the complexity of quantum circuits is rapidly increasing, driving the need for robust methods to aid in their design. Equivalence checking plays a vi…
Sub-Harmonic Control of a Fluxonium Qubit via a Purcell-Protected Flux Line
Johannes Schirk, Florian Wallner, Longxiang Huang +21
Protecting qubits from environmental noise while maintaining strong coupling for fast high-fidelity control is a central challenge for quantum information processing. Here, we demo…
Quantum Annealing with chaotic driver Hamiltonians

Lattice gauge theories (LGTs) can be employed to understand a wide range of phenomena, from elementary particle scattering in high-energy physics to effective descriptions of many-…
Non-Universality from Conserved Superoperators in Unitary Circuits
Marco Lastres, Frank Pollmann, Sanjay Moudgalya
An important result in the theory of quantum control is the "universality" of -local unitary gates, i.e. the fact that any global unitary evolution of a system of qudits can…
Hilbert space fragmentation at the origin of disorder-free localization in the lattice Schwinger model
