A compression protocol for controlled time evolution of local translationally invariant Hamiltonians achieves O(t polylog(t N/ε)) circuit depth with additive control overhead, demonstrated via 414 CNOT gates for iterative phase estimation on a 6×6 triangular lattice and sub-1% energy errors on a 4×4

KnotMosaics is a SageMath package that constructs, validates, and analyzes knot mosaic diagrams while linking them to existing knot invariant computations.
The hybrid BOCS-GP method with adaptive LCB selection finds better objective values than random-point addition in QUBO and HUBO by selecting points that promote search progress within Hamming-distance neighborhoods.
GQPINNs add symmetry awareness to quantum PINNs via equivariant circuits, yielding lower mean absolute error and fewer parameters than standard QPINNs on linear and nonlinear PDE benchmarks.
Crosstalk patterns between quantum circuits on IBM processors are predictable by circuit type and hardware architecture, with high intra-revision consistency and topological decoupling between lattice types.
The authors prove existence of a unitary that maps a two-qubit state to one where a single observable expectation equals the initial concurrence and demonstrate a robust optimal control implementation via numerical simulations.
Presents an optimal gate-packing partitioning scheme for the QFT that aims to minimize e-bit count in distributed quantum systems and validates it on hardware.
Performance evaluation of three QKD protocols in non-turbulent underwater channels via analytical QBER derivation for BBM92 and Monte Carlo validation across water types.
In neutrino oscillations treated as open quantum systems, coherence outlasts steering and negativity under amplitude damping, phase flip, and phase damping, showing memory-induced revivals in non-Markovian regimes.
Authors propose implementing the non-unitary Jastrow-Gutzwiller operator via cascaded VQE on quantum hardware and demonstrate it for the Hubbard model on IBM Q Lagos.
