Recently Shi proved that Toffoli and Hadamard are universal for quantum computation. This is perhaps the simplest universal set of gates that one can hope for, conceptually; It shows that one only needs to add the Hadamard gate to make a 'classical' set of gates quantum universal. In this note we give a few lines proof of this fact relying on Kitaev's universal set of gates, and discuss the meaning of the result.

  1. On the Complexity of the Circuit Width Problem

    cs.CC 2026-06 unverdicted novelty 8.0 of 10

    Deciding circuit width w(f) ≤ k for degree-3 polynomials with no constant term is NP-complete, with 49/48-ε inapproximability, ETH lower bounds, and FPT algorithms.

  2. A sharp interaction-degree threshold for simulating QAOA

    quant-ph 2026-05 unverdicted novelty 7.0 of 10

    There is a sharp threshold at interaction degree 3 where classical sampling from depth-1 QAOA becomes hard enough to collapse the polynomial hierarchy, contrasting with efficient simulation at degree 2 for logarithmic depth.

    Proposal for an ancilla-error-transparent controlled beam splitter gate implemented via Kerr-cat qubits in circuit QED.

  4. Realified tensor networks: quantum circuit simulation on real-valued matrix accelerators

    quant-ph 2026-08 conditional novelty 6.0 of 10

    A graph rewrite maps complex tensor networks to real ones with proven arithmetic overhead at most 3x and measured speedups on real-only NPUs.

    quant-ph 2026-06 unverdicted novelty 6.0 of 10

    Develops an invariant-based framework connecting Pauli Lie algebras to transvection-generated Clifford subgroups for quantum reachability and dynamics analysis.

  6. No-Go Theorem on Fault Tolerant Gadgets for Multiple Logical Qubits

    quant-ph 2026-02 reject novelty 6.0 of 10

    No stabilizer code can implement the full logical Clifford group on multiple logical qubits using transversal gates, fold-transversal gates beyond two qubits, or code automorphisms.

  7. Engineering long-range and multi-body interactions via global kinetic constraints

    quant-ph 2025-05 unverdicted novelty 6.0 of 10

    A driven Bose-Hubbard model with global density-density interactions induces tunable global kinetic constraints for efficient implementation of multi-body gates and entangled states.

  8. AutoQ 2.0: From Verification of Quantum Circuits to Verification of Quantum Programs (Technical Report)

    cs.LO 2024-11 unverdicted novelty 6.0 of 10

    AutoQ 2.0 verifies quantum programs with classical control flow and successfully checks RUS algorithms instantly plus weak-measurement Grover search on 100 qubits in about 20 minutes.

  9. Practical Fidelity Limits of Toffoli Gates in Superconducting Quantum Processors

    quant-ph 2025-09 reject novelty 3.0 of 10

    Benchmarking a decomposed Toffoli gate on IBM quantum hardware yields 56-64% state fidelities, but the claimed state-dependent error pattern is confounded by using different devices.
