A Canadian startup called Xanadu has built a new quantum computer it says can be easily scaled up to achieve the computational power needed to tackle scientific challenges ranging from drug discovery to more energy-efficient machine learning.
Aurora is a “photonic” quantum computer, which means it crunches numbers using photonic qubits—information encoded in light. In practice, this means combining and recombining laser beams on multiple chips using lenses, fibers, and other optics according to an algorithm. Xanadu’s computer is designed in such a way that the answer to an algorithm it executes corresponds to the final number of photons in each laser beam. This approach differs from one used by Google and IBM, which involves encoding information in properties of superconducting circuits.
Aurora has a modular design that consists of four similar units, each installed in a standard server rack that is slightly taller

The manufacturing technique known as 3D printing, now being used everywhere, from aircraft manufacturers to public libraries, has never been more affordable or accessible. Biomedical engineering has particularly benefited from 3D printing as prosthetic devices can be produced and tested more rapidly than ever before. However, 3D printing still faces challenges when printing living tissues, partly due to their complexity and fragility.
Now, with support from the U.S. National Science Foundation, a research team at Boston University (BU) and the Wyss Institute at Harvard University has pioneered the use of gallium, a metal that can be molded at room temperature, to create tissue structures in various shapes and sizes.
This innovative approach to fabrication, engineered sacrificial capillary pumps for evacuation (ESCAPE), was highlighted in a recent study published in Nature, where the team used gallium casts to mold biomaterials. The scaffolds left behind by these casts are then filled with cells cultured to form tissue structures. Vascular structures were some of the first produced using ESCAPE, particularly because of the challenges faced due to blood vessel complexity. Few techniques exist to build large (millimeter-scale) and small (micrometer-scale) structures in scaffolds made of natural materials, making this multiscale fabrication capability a novel approach.
“ESCAPE can be used on several tissue architectures, but we started with vascular forms because blood vessel networks feature many different length scales,”
