Quantum gate teleportation connects atomic qubits in two labs

Physics World: Researchers in Germany have performed a quantum gate operation between two quantum bits (qubits) in different laboratories. This marks a step towards distributed quantum logic, whereby system designers could build modular quantum computers, spreading qubits between different devices while…
