Implementing quantum logic gates with gradient ascent pulse engineering: principles and practicalities
Benjamin D. Rowland, Jonathan A. Jones · Philosophical Transactions of the Royal Society A Mathematical Physical and Engineering Sciences · 2012
We briefly describe the use of gradient ascent pulse engineering (GRAPE) pulses to implement quantum logic gates in nuclear magnetic resonance quantum computers, and discuss a range of simple extensions to the core technique. We then consider a range of difficulties that can arise in practical implementations of GRAPE sequences, reflecting non-idealities in the experimental systems used.
