Quantum mechanics is a fundamental theory that describes nature at the very smallest scales of atoms and subatomic particles. At such scales, objects display some very bizarre properties—for example, having the characteristics of a wave and a particle at the same time.
Breakthrough To Wafer Scale Quantum Processors Using Silicon Isotope And Eventually Trillions Of Qubits
“To progress towards a practical and useful quantum processor, it is now essential to scale up the qubit,” said Louis Hutin, a research engineer in CEA-Leti’s Silicon Components Division. “This development will have to address variability, reproducibility and electrostatic control quality for elementary quantum bricks, as is done routinely for standard microprocessors.”
Various processes in nuclear, medical and other research fields call for the separation of isotopes, a typically energy-intensive task. From the perspective of classical physics, hydrogen isotopes appear identical. But when their quantum nature is considered, their wave signatures are distinct.
Researchers across the world have been trying to make such boron cousins of graphene. The technique developed by the research team at IIT Gandhinagar is not only inexpensive and simple in design, but also results in an aqueous colloid of these nanosheets, which means that a drop of water from this colloid would contain thousands of nanosheets swimming like micro-carpets.
The scientists attempted to find evidence for the existence of S2 in such water-based solutions—as predicted by accepted chemistry calculations—using an advanced piece of equipment known at UWA known as a Raman spectrometer. This incredibly sensitive instrument is designed to detect the bonds between chemicals.
They fired laser pulses at tiny, invisible wires—known as nanowires—which instantly created hot and dense plasma—one of the four fundamental states of matter that does not occur freely on Earth. This plasma created a chain reaction of fusion events
