We propose a platform for implementing a universal, globally driven quantum computer based on a 2D ladder hosting three different species of superconducting qubits. In stark contrast with the existing literature, our scheme exploits the always-on longitudinal ZZ coupling. The latter, combined with specific driving frequencies, enables the reach of a blockade regime, which plays a pivotal role in the computing scheme.

  1. Unlocking the power of global quantum gates with machine learning

    quant-ph 2025-02 conditional novelty 6.0 of 10

    Finite-depth circuits made of global CZ/CX gates and single-qubit rotations can approximate ground states of Heisenberg and toric code Hamiltonians in variational training.

  2. Charging a Dimerized Quantum XY Chain

    quant-ph 2025-02 conditional novelty 4.0 of 10

    For a dimerized XY chain used as a quantum battery, the asymptotic stored energy rises, then slowly increases, then falls as charging parameters cross the two quantum critical lines.
