arXiv:2603.24950v1 Announce Type: new Abstract: Fermionic linear optics (FLO) with Gaussian resources is efficiently classically simulable. We show that this is no longer the case for such quantum cir…
arXiv:2603.24909v1 Announce Type: new Abstract: Collapse-locality is an untested loophole in the violation of Bell's inequalities. The core of the argument is that the time value of photon detection i…
arXiv:2603.24902v1 Announce Type: new Abstract: Magic and entanglement are two measures that are widely used to characterize quantum resources. We study the interplay between magic and entanglement in…
arXiv:2603.24874v1 Announce Type: new Abstract: We investigate congestion-aware control of quantum repeater nodes operating under stochastic traffic and finite memory coherence. Entanglement generatio…
arXiv:2603.24868v1 Announce Type: new Abstract: We introduce Quantum Spectral Authentication (QSA), a primitive for verifying that a remote quantum endpoint still possesses a previously installed secr…
arXiv:2603.24864v1 Announce Type: new Abstract: An electron in quantum confinement takes on a discrete energy spectrum which is defined based on the solution to the Schrodinger Equation for a given po…
arXiv:2603.24822v1 Announce Type: new Abstract: We introduce a coefficient-decoupled matrix product operator (MPO) representation for Pauli-sum operators that separates reusable symbolic operator supp…
arXiv:2603.24805v1 Announce Type: new Abstract: Quantum optics provides a fundamental framework for understanding the interaction between light and matter at the quantum level. Recently, it has been s…
arXiv:2603.24778v1 Announce Type: new Abstract: Quantum mode parameter estimation determines parameters governing the shape of electromagnetic modes occupied by a quantum state of radiation. Canonical…
arXiv:2603.24731v1 Announce Type: new Abstract: We show that any $n$-qubit Clifford unitary can be implemented using at most $2n$ multi-qubit joint measurements. All the multi-qubit joint measurements…
arXiv:2603.24728v1 Announce Type: new Abstract: Accurate ground-state energy calculations remain a central challenge in quantum chemistry due to the exponential scaling of the many-body Hilbert space.…
arXiv:2603.24717v1 Announce Type: new Abstract: We generalize the polynomial-time outcome-complete simulation algorithm for stabilizer circuits in arXiv:2309.08676 to track global phases exactly, yiel…
arXiv:2603.24679v1 Announce Type: new Abstract: Quantum walks constitute a rich area of quantum information science, where multipartite entanglement plays a central role in the dynamics and scalabilit…
arXiv:2603.24671v1 Announce Type: new Abstract: Under decoherence, an initial Gaussian (free-fermion) state evolves into a non-Gaussian mixed state, so the resulting decohered fermionic state is not e…
arXiv:2603.24665v1 Announce Type: new Abstract: Determining whether an observed distribution of events generated in a quantum network is Bell local, i.e., if it admits an alternative realization in te…
arXiv:2603.24654v1 Announce Type: new Abstract: This article presents an argument for why quantum computers could unlock new methods for machine learning. We argue that spectral methods, in particular…
arXiv:2603.24642v1 Announce Type: new Abstract: Non-Hermitian systems generally host complex spectra that bring unique spectral topologies, leading to the spectral braiding and non-Hermitian skin effe…
arXiv:2603.24619v1 Announce Type: new Abstract: This paper proves a conditional structural uniqueness theorem for induced weight on robust record sectors within an admissible Hilbert record layer. Its…
