Single-qubit optical quantum fingerprinting
Rolf T. Horn, S. A. Babichev, Karl-Peter Marzlin +2
We analyze and demonstrate the feasibility and superiority of linear optical single-qubit fingerprinting over its classical counterpart. For one-qubit fingerprinting of two-bit mes…
Geometric phase distributions for open quantum systems
K. -P. Marzlin, S. Ghose, B. C. Sanders
In an open system, the geometric phase should be described by a distribution. We show that a geometric phase distribution for open system dynamics is in general ambiguous, but the…
Inconsistency in the application of the adiabatic theorem
Karl-Peter Marzlin, Barry C. Sanders
The adiabatic theorem states that an initial eigenstate of a slowly varying Hamiltonian remains close to an instantaneous eigenstate of the Hamiltonian at a later time. We show tha…
