Description
Quantum information experiments are advancing rapidly with realisations of real-time quantum error correction [1], demonstrations of variational quantum computing, for example, in metrology [2], and explorations of novel topological phases [3]. Underpinning these advancements is the requirement for high fidelity gates with low and uncorrelated errors between gates and qubits [4]. However, as machines are scaled up in both the number of qubits and algorithm length, it becomes increasingly challenging to keep error rates low in hardware alone.
Quantum control enables the suppression of errors to a level that exceeds limitations set by physical hardware when using primitive gate implementations. I will demonstrate the identification, reduction and homogenisation of errors across a qubit register, reducing overhead and pre-conditioning the system for quantum error correction. In addition, I will identify potential applications of these techniques in current quantum information experiments.
