The operation of quantum computers, systems that process information leveraging quantum mechanical effects, relies on the implementation of quantum logic gates. These are essentially operations that ...

Scientists have developed a number of quantum computing systems that use ions or electrons as bits of data; mathematical "operations" can be performed on them with beams of light or electrical pulses.

A hybrid quantum circuit is constructed by using both local unitary gates and non-unitary single qubit projective measurement gates. We find a quantum phase transition through tuning the measurement ...
