Computers are renowned for flexibility, running everything from game consoles to stock exchanges. But at the level of computation, most computers rely on arrays of identical processors called cores. Now, a team at Princeton University has built a hardware platform that allows different kinds of computer cores to fit together, allowing designers to customize systems in new ways.

The goal is to create new systems that parcel out tasks among specialized cores, increasing efficiency and speed.

On top of multi–core collaboration, even more gains are achievable when cores needn’t all rely on the same basic programming code that tells a core how to handle its processing jobs. Designers call this basic code an Instruction Set Architecture (ISA). Well-established ISAs include Intel x86, commonly found in laptops, ARM in smartphones, and POWER in IBM mainframes. Besides mixing together cores specialized for different ISAs, researchers are also interested in developing hybrid ISAs to underpin new processor designs, exploiting the potential of new, cutting-edge, open-source ISAs like RISC-V ISA.

“Beam me up” is one of the most famous catchphrases from the Star Trek series. It is the command issued when a character wishes to teleport from a remote location back to the Starship Enterprise.

While human teleportation exists only in science fiction, teleportation is possible in the subatomic world of quantum mechanics—albeit not in the way typically depicted on TV. In the quantum world, teleportation involves the transportation of information, rather than the transportation of matter.

Last year scientists confirmed that information could be passed between photons on computer chips even when the photons were not physically linked.

“Irrational Computing” has interlinked a series of untreated crystals and minerals to create a primitive signal processor.

Scientists managed another breakthrough. They built a quantum computer that can execute the difficult Shor’s algorithm. It’s just five atoms big, but the experts claim it will be easy to scale it up.

A new system called DORIS fixes one major problem with making DNA data storage widespread, including letting users “delete” data as well as store it.

The launch of QUA will let researchers run even the most complex programs combined with classical processing, says creator Quantum Machines.

Honeywell’s enterprise customers can now access the company’s 64 quantum volume computer.

In the vast majority of superconducting materials, Cooper pairs have what is known as even parity, which essentially means that their wave function does not change when electrons swap spatial coordinates. Conversely, some unconventional superconductors have been found to contain odd-parity Cooper pairs. This quality makes these unconventional materials particularly promising for quantum computing applications.

Past studies have predicted that noncentrosymmetric superconductors, which have a crystal structure with no center of inversion, could exhibit unique and unusual properties. In recent years, noncentrosymmetric superconductors have become a popular topic of research due to the structure of the Cooper pairs contained within them, which have a mixture of odd and even parity.

CaPtAs is a new noncentrosymmetric superconductor discovered by researchers at Zhejiang University. Together with scientists at the Paul Scherrer Institut and other institutes worldwide, these researchers have recently carried out a study investigating unconventional superconductivity in this compound. Their paper, published in Physical Review Letters, offers evidence that in its superconducting state, CaPtAs simultaneously exhibits both nodal superconductivity and broken time-reversal symmetry (TRS).
