Scientists one step closer to a fully functioning quantum computer

Researchers from Purdue University and the University of Rochester demonstrate a new method of relaying information by transferring the state of electrons.

Quantum error correction requires that individual qubits interact with many other qubits. But two electrons in the same quantum state cannot sit on top of each other. A surprising consequence of this is that if the electrons are close enough, their states will swap back and forth. Transmitting the state of an electron back and forth across an array of qubits, without moving the position of electrons is an important step for showing how information can be transmitted quantum-mechanically. (University of Rochester)
