Quantum Computation with Trapped Ions

Written by admin Published in
Ion traps are one of the promising platforms for quantum computation.
To realize quantum gates with arbitrary precision, single qubit and two qubit operations should be performed below the fault-tolerance threshold, where noise and other decoherence effects must be compensated. single qubit operations below the threshold had been performed in various systems. However, two qubit operations have yet to achieve low error rates. Using ultra-fast laser pulses, the main obstacle for realizing fault-tolerant two qubit gates is the amplitude noise of the laser. In this project we introduce a way to counter this noise using composite pulses, thus facilitate in generating robust two qubit gate for trapped ions using ultra-fast laser pulses.
