Globally controlled universal quantum computation with arbitrary subsystem dimension
Gerardo A. Paz-Silva, Gavin K. Brennen, Jason Twamley · Physical Review A · 2009
We present a scheme to perform universal quantum computation using global control with an arbitrary subsystem dimension (not necessarily finite). The scheme is developed over a one spatial dimension $N$-element array, using only mirror-symmetric logical encoding, global pulses for single subsystem operations, uniform Ising-type interaction, and an all zero initial pure state. A mechanism using ancillary degrees of freedom for subsystem specific measurement is also presented.
