Quantum bus

A quantum bus is a device which can be used to store or transfer information between independent qubits in a quantum computer, or combine two qubits into a superposition. The concept was first demonstrated by researchers at Yale University and the National Institute of Standards and Technology (NIST) in 2007. Prior to this experimental demonstration, the quantum bus had been described by scientists at NIST as one of the possible cornerstone building blocks in quantum computer architecture.
