Abstract

A quantum computer can be implemented with cold ions confined in a linear trap and interacting with laser beams. Quantum gates involving any pair, triplet, or subset of ions can be realized by coupling the ions through the collective quantized motion. In this system decoherence is negligible, and the measurement (readout of the quantum register) can be carried out with a high efficiency.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • H2 significantly increases the qubit number and decreases the physical resources per qubit while matching or surpassing the high circuit fidelity of the previous generation system.

    “The new machine, Quantinuum System Model H2, significantly increases the qubit number and decreases the physical resources per qubit, all while matching-and in some instances surpassing-the high circuit fidelity of our previous generation system [5].”

    From A Race-Track Trapped-Ion Quantum Processor (2023) · cites this paper as [5]

  • H0 and H1 demonstrated many key components of the QCCD architecture and achieved high-fidelity gates with arbitrary two-qubit couplings.

    “Our first generation hardware, H∅ and H1 (based on the same linear trap design) [5,15], demonstrated many key components of the QCCD architecture and achieved high-fidelity gates with arbitrary two-qubit couplings.”

    From A Race-Track Trapped-Ion Quantum Processor (2023) · cites this paper as [5]

  • Since the initial operation of the linear trap, the qubit number N increased fivefold, from 4 to 20, while two-qubit gate errors decreased by roughly a factor of 5.

    “Since the initial operation of the linear trap, the qubit number N increased fivefold, from 4 in its initial mode of operation [5] to 20 in its latest [15], while two-qubit gate errors decreased by roughly a factor of 5.”

    From A Race-Track Trapped-Ion Quantum Processor (2023) · cites this paper as [5]

  • Qubit measurement and reset may be performed in the middle of a quantum circuit while quantum information is preserved on other qubits.

    “Similar to previous work [5,15], qubit measurement and reset may be performed in the middle of a quantum circuit while quantum information is preserved on other qubits.”

    From A Race-Track Trapped-Ion Quantum Processor (2023) · cites this paper as [5]

  • Only two methods have been used to demonstrate quantum logic gates: ion traps and nuclear magnetic resonance (NMR).

    “only two methods have been used to demonstrate quantum logic gates: ion traps, 3, 4 and nuclear magnetic resonance (NMR). 5, 6”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
