Quantum information scientists at the Department of Energy’s Oak Ridge National Laboratory successfully demonstrated a device that combines key quantum photonic capabilities on a single chip for the first time.
The study published in Optica Quantum focused on a type of quantum computing that relies on light particles, or photons, to build qubits and to store and transmit information. Qubits, unlike the binary bits used in classical computing, can exist simultaneously in more than one state via quantum superposition, which allows combinations of physical values to be encoded on a single object. Quantum networking would connect quantum devices over distances — the first step toward a quantum internet.
