Proposal of quantum arrival-time measurement with a Bose-Einstein condensate
Pascal Naidon, Lucas Happ, Denis Boiron·Jun 18, 2026
This work shows how a Bose-Einstein condensate of ultracold atoms could be used to address a long-standing question in quantum theory: how much time does it take for a particle to reach a detector? To this end, we propose a realistic experimental set...
Extracting the physical content of Liouvillian eigenmodes: Semiclassical quantization
Ashlin V Thomas, Felix Fritzsch, Masudul Haque +1 more·Jun 18, 2026
Unlike in closed quantum systems where individual energy eigenstates are understood as physical excitations, open quantum systems have distinct right and left eigenstates of the Liouvillian that decay with time and are difficult to interpret. Here we...
Vine Codes: Low-Overhead Quantum LDPC Codes on a Planar Square Grid
Georgia M. Nixon, Campbell K. McLauchlan, Charles C. L. van Rest·Jun 18, 2026
The surface code is a promising route towards large-scale quantum computing, requiring only nearest-neighbour gates amenable to superconducting hardware. However, surface codes incur large qubit overheads. Novel quantum low-density parity check (qLDP...
Anomalous magneto-optical response at $\mathrm{RuO_2 / WSe_2}$ van der Waals interface
Muhammad Hassan Shaikh, Abhijith Puthiya Veettil, Collin Maurtua +9 more·Jun 18, 2026
Ruthenium dioxide ($\mathrm{RuO_2}$) has been proposed as an altermagnetic candidate, although its magnetic ground state remains controversial. Here, we probe weak interfacial magnetic states at the surface of (001)-oriented $\mathrm{RuO_2}$ films us...
Mitigating Trotter Errors via Post-Processed Symmetry Restoration
Sangjin Lee, Sangkook Choi·Jun 18, 2026
Quantum simulation is a powerful tool for exploring complex quantum many-body systems such as condensed matter physics and gauge theories. Trotterization, which approximates the ideal time evolution operator by decomposing it into a sequence of local...
Random Projections for Multi-Copy Quantum Algorithms
Xiaoyu Liu, Jordi Tura, Johannes Knörzer·Jun 18, 2026
Estimating nonlinear properties of quantum states is a central task in quantum information science. Multivariate traces, $\mathrm{tr}(ρ_1 \cdots ρ_K)$, and nonlinear observables such as $\mathrm{tr}(ρ^K)$, for integer $K$, can be accessed through col...
Optimal multi-spectral squeezing via deterministic 2D-phase optimization
Bastien Oriot, Peter Namdar, Emilie Gillet +2 more·Jun 18, 2026
Optimization routines are ubiquitous in quantum information technologies and essential to reach the resource levels required by quantum protocols. Specifically, multi-spectral squeezing for use in such protocols requires that losses be kept minimal a...
Truncated Wigner dynamics of biclique quantum spin glasses
Dries Sels·Jun 18, 2026
Quantum spin glasses are often considered testbeds for studying quantum optimization algorithms and as such have been the subject of various quantum advantage claims. Here we investigate the near adiabatic dynamics of biclique quantum spin glasses wi...
Operator Learning for efficient Quantum Computation
Paul Over, Sergio Bengoechea, Leonardo Borello Busilacchi +3 more·Jun 18, 2026
An efficient implementation of quantum algorithms is often hindered by the lack of efficient primitives for operators and state preparation. This limits both the ability of near-term quantum hardware to simulate complex problems and the potential of ...
Quantum-Accelerated Self-Consistent Field: A Hybrid Algorithm
Alexis Ralli, Tim Weaving, Thomas M. Bickley +2 more·Jun 18, 2026
We present the Grover adaptive search self-consistent field (GAS-SCF) algorithm. GAS-SCF leverages quantum arithmetic to construct an efficient oracle that marks target states (Fock states) which improve upon some initial classical energy estimate. A...

We report the first results of the magnetic dipole hyperfine structure (HFS) constants of neutral $\mathrm{Li}$, Li-like $\mathrm{Be}$, neutral $\mathrm{Na}$, and Na-like $\mathrm{Mg}$ using a modified version of the Quantum Annealer Eigensolver (QAE...
Multi-objective design of photon blockade for bright single-photon sources
Sunkyu Yu, Xianji Piao, Namkyoo Park·Jun 18, 2026
High-quality single-photon sources, realized through saturable emitters, photon blockade, or heralded pair generation, are indispensable building blocks for photonic quantum platforms. Although these mechanisms suppress multiphoton emission through d...
Optimizing resource allocation for accuracy in noisy variational quantum algorithms
Harshit Verma, Thomas Ayral, Alexia Auffèves +1 more·Jun 18, 2026
For quantum algorithms to achieve their full potential, we need methodologies to optimize them, such as reaching a given output accuracy with minimal resource costs. Here, we develop such a methodology for a class of Noisy Intermediate-Scale Quantum ...
QPU-scale randomized benchmarking via Bell-pair injection
Haripriya Pettugani, María Aguado-Yáñez, Astryd Park +2 more·Jun 18, 2026
Mirror randomized benchmarking (MRB) is an established technique that provides a global error metric at the scale of a whole QPU. To expand upon this we introduce Mirror Quantum Awesomeness (MQA), a hybrid protocol that adds a structured entangling l...
