Physicists set new record for quantum teleportation with matter qubits

In most demonstrations of quantum teleportation between remote atomic qubits, the atoms exist in free space. In a new study, scientists have discovered that trapping the atoms in optical cavities can overcome some of the previous obstacles facing matter teleportation, which enables an improvement in efficiency of almost 5 orders of magnitude and teleportation across a record-breaking distance of 21 m. These improvements in quantum teleportation could open the doors to realizing quantum networks with many nodes for teleporting qubits to various destinations.
