Hemodynamic stability with remimazolam versus propofol for general anesthesia in acute ischemic stroke thrombectomy: a randomized controlled trial
Stroke, Ahead of Print. <br />BACKGROUND:The benefit of endovascular thrombectomy (EVT) in patients with stroke with proximal large vessel occlusion in the anterior circulation has been confirmed by several randomized controlled trials. However, evidence regarding EVT for anterior cerebral artery occlusion (ACAo) …

A digitally controlled silicon quantum processing unit
A silicon quantum processing unit executes high-fidelity multiqubit circuits, with all time-varying control signals generated by a digitally programmed cryogenic complementary metal–oxide–semiconductor controller and delivered to the low-noise, exchange-only qubit device through a high-density superconducting ribbon …
Weight-four parity checks in a spin-shuttling architecture
A silicon spin-qubit device comprising a shuttling bus for transporting qubits is used to achieve parity checks up to weight four, highlighting the feasibility and benefits of incorporating shuttling into semiconductor quantum processors.
The realization of fractional quantum Hall (FQH) states in cold atomic gases is a long-standing goal in quantum simulation. Established approaches, including rapidly rotating gases and tight-binding lattices, are often hampered by low interaction energies and small many-body energy gaps. While optical flux lattices …

Motional refocusing for trap-off Rydberg gates
Rydberg entangling gates in optical-tweezer arrays are commonly executed with the trapping light switched off, so every gate contains a release--and--recapture cycle that heats the atomic motion and can ultimately limit circuit depth. We develop a motional refocusing protocol that exactly removes this heating in the …
A technique for realizing a universal set of fault-tolerant quantum operations is the code switching method, which leverages two quantum codes with complementary sets of transversal gates. To date, the application of this technique has been largely limited to families of color codes supporting a logical $T$ gate. No …

An entangling gate for dual-rail erasure qubits
A fast, low-error entangling gate for dual-rail cavity erasure qubits preserves a strong error hierarchy, advancing scalable quantum error correction with substantially improved fault-tolerant performance.
In semiconductor single-spin qubits, high-fidelity quantum gates have been demonstrated; however, achieving consistent performance remains challenging due to variations in driven qubit coherence, which is less explored than free-evolution coherence such as $T_2^*$. Here, we report single-qubit gate fidelities above …
