University of Massachusetts Amherst researchers have devised a novel form of
quantum error correction (QEC) featuring spontaneous, or passive,
correction.  The passive QEC method specifically designs the friction or
dissipation experienced by a quantum bit (qubit). UMass Amherst's Chen Wang
said, "Although our experiment is still a rather rudimentary demonstration,
we have finally fulfilled this counterintuitive theoretical possibility of
dissipative QEC. Looking forward, the implication is that there may be more
avenues to protect our qubits from errors and do so less expensively.
Therefore, this experiment raises the outlook of potentially building a
useful fault-tolerant quantum computer in the mid to long run."
