Increased stiffness with medial column screw supplementation of lateral locking plate for distal femur fractures: a biomechanical study.

Introduction: We propose and assess the biomechanical stability of medial column screw supplementation in a synthetic distal femur fracture model.

Materials And Methods: Twenty-four low density synthetic femora modeling osteoporotic, intraarticular distal femur fractures with medial metaphyseal comminution were split into two fixation groups: (1) lateral locking distal femur plate (PA- plate alone) and (2) lateral locking distal femur plate with a 6.5 mm fully threaded medial cannulated screw (PWS- plate with screw).

Injury to the Popliteal Artery and Vein During Open Fibular Collateral Ligament Reconstruction: A Case Report.

Case: We present a case involving a 26-year-old male who sustained an iatrogenic injury to the right popliteal artery and vein during open fibular collateral ligament reconstruction. The lesions were repaired immediately and required subsequent procedures on postoperative day 1.

Conclusions: Iatrogenic vascular injuries during knee surgery can be devastating for patients and may lead to increased medical costs, unexpected hospital admissions, and additional surgical procedures.

Towards photonic quantum simulation of ground states of frustrated Heisenberg spin systems.

Photonic quantum simulators are promising candidates for providing insight into other small- to medium-sized quantum systems. Recent experiments have shown that photonic quantum systems have the advantage to exploit quantum interference for the quantum simulation of the ground state of Heisenberg spin systems. Here we experimentally characterize this quantum interference at a tuneable beam splitter and further investigate the measurement-induced interactions of a simulated four-spin system by comparing the entanglement dynamics using pairwise concurrence.

Experimental quantum teleportation over a high-loss free-space channel.

We present a high-fidelity quantum teleportation experiment over a high-loss free-space channel between two laboratories. We teleported six states of three mutually unbiased bases and obtained an average state fidelity of 0.82(1), well beyond the classical limit of 2/3.

Experimental realization of light with time-separated correlations by rephasing amplified spontaneous emission.

Amplified spontaneous emission is a common noise source in active optical systems, it is generally seen as being an incoherent process. Here we excite an ensemble of rare earth ion dopants in a solid with a π pulse, resulting in amplified spontaneous emission. The application of a second π pulse leads to a coherent echo of the amplified spontaneous emission that is correlated in both amplitude and phase.

Quantum teleportation over 143 kilometres using active feed-forward.

The quantum internet is predicted to be the next-generation information processing platform, promising secure communication and an exponential speed-up in distributed computation. The distribution of single qubits over large distances via quantum teleportation is a key ingredient for realizing such a global platform. By using quantum teleportation, unknown quantum states can be transferred over arbitrary distances to a party whose location is unknown.
