Quantum computing has far to head before becoming truly mainstream , but that certainly hasn’t stopped us from indulging in dreams of a qubit-based existence . The most recent little bit of fantasy fodder comes from the University of California, Santa Barbara, where researchers became the primary to mix a quantum processor with memory mechanisms on a single chip. To do that, Matteo Mariantoni and his team of scientists connected two qubits with a quantum bus and linked each of them to a memory element, able to storing their current values within the same way that RAM stores data on conventional computers. These qubit-memory links also contained arrays of resonators — jagged, yet easily controlled circuits that could store values for shorter periods of time. The qubits, meanwhile, were constructed using superconducting circuits, allowing the UCSB team to nestle their qubits even closer together, according to the von Neumann architecture that governs most commercial computers. Once everything was in place, the researchers used their system to run complex algorithms and operations that may be eventually used to decode data encryption. The next move, needless to say, is to scale up the design, though Mariantoni says that isn’t an excessive amount of of an issue, because of his system’s resonators — which, in keeping with him, “represent the way forward for quantum computing with integrated circuits.”
