• "Qubit-oscillator system under ultrastrong coupling and extreme driving", Hausinger, Grifoni, 2011

  Publikation

  We introduce an approach to studying a driven qubit-oscillator system in the ultrastrong coupling regime, where the ratio g/Omega between coupling...

• "Ancilla-assisted sequential approximation of nonlocal unitary operations", Saberi, 2011

  Publikation

  We consider the recently proposed "no-go" theorem of Lamata et al. [Phys. Rev. Lett. 101, 180506 (2008)] on the impossibility of sequential...
