arXiv:2604.05325v1 Announce Type: new Abstract: Quantum battery capacity, as a critical metric for quantifying energy storage and release in quantum systems, exhibits complex behaviors in curved space…
arXiv:2604.05321v1 Announce Type: new Abstract: In this work we propose an addressing scheme for quantum networks which relies on quantum states held by devices. Quantum network devices use their addr…
arXiv:2604.05317v1 Announce Type: new Abstract: This paper proposes a scalable planning algorithm for creating defect-free atom arrays in neutral-atom systems. The algorithm generates a $\mathcal{O}(\…
arXiv:2604.05218v1 Announce Type: new Abstract: We find that rank deficiency of the local Hamiltonian in a classically fragmented model is the key mechanism leading to quantum Hilbert space fragmentat…
arXiv:2604.05170v1 Announce Type: new Abstract: In this paper, we formulate the phase space description of qubit systems using coadjoint orbits of $SU(2)$ and the Stratonovich-Weyl correspondence, yie…
arXiv:2604.05133v1 Announce Type: new Abstract: In this paper, we introduce a new quantum query lower bound framework. It is inspired by Zhandry's compressed oracle technique, but it also subsumes the…
arXiv:2604.05126v1 Announce Type: new Abstract: Quantum low-density parity-check (qLDPC) codes can encode many logical qubits within a single code block at low physical qubit overhead, yet magic state…

arXiv:2604.05036v1 Announce Type: new Abstract: Efficient classical simulation of noisy intermediate-scale quantum (NISQ) circuits has been a topic of intense study over the past few years. The majori…
arXiv:2604.05032v1 Announce Type: new Abstract: Exponential complexity of many-body wave functions limits accurate numerical simulations of real-time dynamics, especially beyond 1D, where rapid entang…
arXiv:2604.05031v1 Announce Type: new Abstract: Understanding the structure of operators that commute with $k$ identical replicas of unitary ensembles, also known as their $k$-commutants, is an import…
Why quantum security must be on every CIO’s 2026 priority list Route Fifty
IQM Quantum Computers has completed a world-first sale of a quantum system to a private enterprise, with Poland’s Galaxy Systemy Informatyczne acquiring a 54-qubit computer. This deployment will estab…
