Limitations of Passive Protection of Quantum Information
Fernando Pastawski, Alastair Kay, Norbert Schuch +1
The ability to protect quantum information from the effect of noise is one of the major goals of quantum information processing. In this article, we study limitations on the asympt…
Selective and Efficient Quantum Process Tomography
Ariel Bendersky, Fernando Pastawski, Juan Pablo Paz
In this paper we describe in detail and generalize a method for quantum process tomography that was presented in [A. Bendersky, F. Pastawski, J. P. Paz, Physical Review Letters 100…
How long can a quantum memory withstand depolarizing noise?
Fernando Pastawski, Alastair Kay, Norbert Schuch +1
We investigate the possibilities and limitations of passive Hamiltonian protection of a quantum memory against depolarizing noise. Without protection, the lifetime of a single qubi…
