Data from: Quantum computation of frequency-domain molecular response properties using a three-qubit iToffoli gate
<p>The quantum computation of molecular response properties on near-term quantum hardware is a topic of substantial interest. Computing these properties directly in the frequency domain is desirable, but the circuits require large depth if the typical hardware gate set consisting of single- and two-qubit gates is used. Here, we report the application of a high-fidelity multipartite gate, the iToffoli gate, to the computation of frequency-domain response properties of diatomic molecules. The iToffoli gate enables a ~50% reduction in circuit depth and ~40% reduction in circuit execution time compared to the traditional gate set. We show that the molecular properties obtained with the iToffoli gate exhibit comparable or better agreement with theory than those obtained with the native CZ gates. Our work is among the first demonstrations of the practical usage of a native multi-qubit gate in quantum simulation, with diverse potential applications to near-term quantum computation.</p>

Efficient quantum gates for individual nuclear spin qubits by indirect control
<p>Hybrid quantum registers, such as electron-nuclear spin systems, have emerged as promising hard-<br> ware for implementing quantum information and computing protocols in scalable systems. Neverthe-<br> less, the coherent control of such systems still faces challenges. Particularly, the lower gyromagnetic<br> ratios of the nuclear spins cause them to respond slowly to control fields, resulting in gate times<br> that are generally longer than the coherence time of the electron. Here, we demonstrate a scheme<br> for circumventing this problem by indirect control: We apply a small number of short pulses only<br> to the electron and let the full system undergo free evolution under the hyperfine coupling between<br> the pulses. Using this scheme, we realize robust quantum gates in an electron-nuclear spin system,<br> including a Hadamard gate on the nuclear spin and a controlled-NOT gate with the nuclear spin<br> as the target qubit. The durations of these gates are shorter than the electron coherence time, and<br> thus additional operations to extend the system coherence time are not needed. Our demonstration<br> serves as a proof of concept for achieving efficient coherent control of electron-nuclear spin systems,<br> such as NV centers in diamond. Our scheme is still applicable when the nuclear spins are only<br> weakly coupled to the electron.</p>
High-fidelity photonic quantum logic gate based on near-optimal Rydberg single-photon source
<p>Compared to other types of qubits, photon is one of a kind due to its unparalleled advantages in long-distance quantum information exchange. Therefore, photon is a natural candidate for building a large-scale, modular optical quantum computer operating at room temperature. However, low-fidelity two-photon quantum logic gates and their probabilistic nature result in a large resource overhead for fault tolerant quantum computation. While the probabilistic problem can in principle be solved by employing multiplexing and error correction, the fidelity of linear-optical quantum logic gate is ultimately limited by the imperfections of single photons. Here, we report the demonstration of a linear-optical quantum logic gate with truth table fidelity of 99.84(3)% and entangling gate fidelity of 99.69(4)% post-selected upon the detection of photons. The achieved high gate fidelities are made possible by our near-optimal Rydberg single-photon source. Our work paves the way for scalable photonic quantum applications based on near-optimal single-photon qubits and photon-photon gates.</p>
