Quantum Cut Sparsifiers

quant-ph · 2026-06-08 · unverdicted · novelty 7.0

Any n-qubit QC Hamiltonian sparsifies to Õ(n/ε²) terms preserving all state energies within 1±ε using invariant subspace decomposition and the Alon-Kozma operator inequality.

Randomized simulation of quantum channels using small ancilla

quant-ph · 2026-06-07 · unverdicted · novelty 7.0

Any unital quantum channel on d dimensions admits exact simulation with ancilla dimension k and success probability Ω(k/log d) via randomization and postselection; the bound is tight and fails for strongly non-unital channels.
