Deterministic and Unambiguous Dense Coding
Shengjun Wu, Scott M. Cohen, Yuqing Sun +1
Optimal dense coding using a partially-entangled pure state of Schmidt rank and a noiseless quantum channel of dimension is studied both in the deterministic case wher…

Unambiguous unitary quantum channels
Shengjun Wu, Xuemei Chen
Unambiguous unitary maps and unambiguous unitary quantum channels are introduced and some of their properties are derived. These properties ensure certain simple form for the measu…

Atemporal diagrams for quantum circuits
Robert B. Griffiths, Shengjun Wu, Li Yu +1
A system of diagrams is introduced that allows the representation of various elements of a quantum circuit, including measurements, in a form which makes no reference to time (henc…
