@informaq.bsky.socialResearchers demonstrated parallel, single-gate creation of 4-qubit entangled states using nitrogen-vacancy centers in diamond, achieving 14.8 μs gate times with 0.92 fidelity—ten times faster than sequential approaches while operating at room temperature.
@informaq.bsky.socialDemonstrates entanglement generation between spatially separated multi-photon systems via mode swapping in three-mode interferometers, advancing scalable optical quantum computing approaches.
@informaq.bsky.socialKean Chen and Qisheng Wang developed improved estimators for Rényi and Tsallis entropies achieving near-optimal sample complexity, significantly reducing data requirements and enabling more practical characterization of quantum states.
@informaq.bsky.socialTwo-player quantum games exhibit sudden entanglement birth and death under decoherence. State-dependent quantum correlations reveal how noise restricts robust entanglement generation in TFIM-based systems.
