介绍:A superselection rule is a restriction that arises through the lack of a classical reference frame and the states that circumvent it (the resource) are quantum reference frames.
Recently, there has been much interest in a new kind of “unspeakable” quantum information that stands to regular quantum information in the same way that a di..
Abstract: Due to Lorentz invariance and locality, physical laws are invariant under
simultaneous Charge-Parity-Time (CPT) inversion, which makes this symm..
We show that appropriate superpositions of motional states are a reference frame<br/>resource that enables breaking of time-reversal superselection so that tw..
