Remote entanglement is crucial for quantum computing, sensing, and communication. Traditional methods for entanglement generation often depend on direct interactions between quantum bits (qubits) or the exchange of entangled photons. In this study, we demonstrate an alternative approach, where we create and preserve entanglement between two noninteracting qubits through dissipation into a shared waveguide.

While dissipation is typically viewed as detrimental, tailored dissipation can be harnessed to drive a system into complex quantum states while actively protecting it from decoherence. This approach, known as autonomous stabilization, has been previously used to create entanglement. However, entanglement stabilization has been confined to short distances due to the challenge of engineering shared dissipation between remote sites. Our experiment overcomes this challenge by employing an open waveguide as a one-dimensional photonic bath. We demonstrate that, under appropriate conditions, the interference of photons emitted into a waveguide from two qubits can stabilize them in an entangled stationary state when the qubits are strongly driven. Crucially, we can reconstruct the entangled state despite significant waveguide-induced dissipation by measuring the emitted photons. Our demonstration is made possible by precise control over qubit frequencies and efficient qubit-waveguide interfaces in superconducting circuits.

A team led by scientists at the Department of Energy’s Oak Ridge National Laboratory identified and successfully demonstrated a new method to process a plant-based material called nanocellulose that reduced energy needs by a whopping 21%. The approach was discovered using molecular simulations run on the lab’s supercomputers, followed by pilot testing and analysis.

The method, leveraging a solvent of sodium hydroxide and urea in water, can significantly lower the production cost of nanocellulosic fiber — a strong, lightweight biomaterial ideal as a composite for 3D-printing structures such as sustainable housing and vehicle assemblies. The findings support the development of a circular bioeconomy in which renewable, biodegradable materials replace petroleum-based resources, decarbonizing the economy and reducing waste.

Colleagues at ORNL, the University of Tennessee, Knoxville, and the University of Maine’s Process Development Center collaborated on the project that targets a more efficient method of producing a highly desirable material. Nanocellulose is a form of the natural polymer cellulose found in plant cell walls that is up to eight times stronger than steel.

Rocket horizon, led by a team from MIT, represents a pioneering interdisciplinary effort to create sustainable lunar habitats.

One contract focuses on Canopy’s transpiration-cooled TBS. Under a second contract, Canopy will embed high-temperature sensors in the TPS material.

Denver-based Canopy was founded in 2021 to develop manufacturing processes that rely on software, automation and 3D-printing to supply heat shields for spacecraft and hypersonic vehicles.
