Abstract

Conditional operations on quantum states are a key part of quantum technologies, particularly quantum computation. It is often assumed that measurements play an indispensable role in this process. In this paper we show that the useful aspects of classical measurements, particularly robustness against environmental noise, can be realized by an ensemble of unitary gates. We utilize error correction circuitry and concatenation to create a robust coded state which can be used as a general replacement for a classical measurement result. Computation on multiple coded states, as well as conditional quantum operations based on these results, can be performed reliably.
