A cryptographic preprint offers a theoretical construction whose security depends on a post-quantum hardness assumption.
The preprint identifies faults at the junction of logical strings in a particular syndrome-extraction schedule.
DAWG reduces reliance on an extra correction stage in numerical tests. Its hardware latency remains an estimate.
A preprint probes measurement-induced localization in a solid-state experiment, with an important limit at high measurement rates.
The proposal combines qubits and oscillator modes. Its reported scattering results come from tensor-network simulations.
An October 21 preprint separates state-transfer fidelity from the harder task of operating across processors.
A preprint studies the circuits behind Grover search, with hardware tests limited to an eight-candidate example.
Drawing counts directly avoids generating every simulated shot when a workflow needs only the final frequency table.
A new theoretical circuit reaches the same direct success probability as an earlier design with half its auxiliary photons.
Quantum Hamiltonian Descent is extended to parametric circuits in a theory and simulation study.
