Distinguishability of countable quantum states and von Neumann lattice
Ryuitiro Kawakubo, Tatsuhiko Koike
Condition for distinguishability of countably infinite number of pure states by a single measurement is given. Distinguishability is to be understood as possibility of an unambiguo…

Spin Amplification with Inhomogeneous Broadening
Suguru Endo, Yuichiro Matsuzaki, William J. Munro +1
A long-lived qubit is usually well-isolated from all other systems and the environments, and so is not easy to couple with measurement apparatus. It is sometimes difficult to imple…

Time-Optimal Transfer of Coherence
A. Carlini, T. Koike
We provide exact analytical solutions for the problem of time-optimal transfer of coherence from one spin polarization to a three-fold coherence in a trilinear Ising chain with a f…
