Graphene at cryogenic temperatures is making quantum computing increasingly viable

Importantly, the sensor’s behaviour is precise, repeatable, and stable, through repeated temperature cycling from high (300 K) to low (1.8K). Therefore, to achieve the highest performance quantum computer, with maximum efficacy and minimum decoherence, requires magnetic shielding that can exist and operate at very low temperatures. Achieving close control of qubit states, to avoid occurrences such as decoherence, is key to delivering robust, effective quantum computing. Graphene at cryogenic temperatures is making quantum computing increasingly viable Author : Ellie Galanis, Product Owner, Paragraf Quantum computing is the ultimate hardware accelerator. What conventional electronic circuits, of all types and at all levels of complexity, have in common, is their physical nature. By comparison, Paragraf’s GHS only needs nA’s of current and dissipates pW levels of power, six orders of magnitude better than other cryogenic magnetic sensors. Such essential close performance monitoring, measurement and control is extremely challenging at cryogenic temperatures, and very difficult for conventional sensing devices.
