Quantum bookkeeping has a long way to go before bewitching truly mainstream, but that doubtlessly hasn't stopped us from indulging in dreams of a qubit-based existence. The latest bit of fantasy fodder comes from the health center of California, Santa Barbara, where researchers have become the first to combine a quantum processor with memory mechanisms on a single chip. To do this, Matteo Mariantoni and his team of scientists connected two qubits with a quantum bus and linked each of them to a memory element, capable of storing their current values in the same way that RAM stores data on au fait computers. These qubit-memory links also contained arrays of resonators -- jagged, yet easily drug circuits that can 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, in grant with the von Neumann style

share this: that governs most mercantile computers. Once aggregate was in place, the researchers used their system to run complex algorithms and supervision study that could be eventually used to decode data encryption. The next step, of course, is to scale up the design, though Mariantoni says that shouldn't be too much of a problem, thanks to his system's resonators -- which, proper to him, "represent the future of quantum calculating with logic circuit circuits."
