Quantum computing, here we come: A qubit data bus may soon be possible

Transporting information from one place to another is a key part of any computing platform, and now researchers have figured out a way to make it possible in the quantum world.To prove their point, they demonstrated what's known as perfect state transfer on a photonic qubit that's entangled with another qubit at a different location.In traditional computing, numbers are represented by either 0s or 1s. Quantum computing relies on atomic-scale quantum bits, or “qubits,” that can be sim
