In this [https://arxiv.org/abs/1205.2300 example protocol] quantum state tomography is performed using compressed sensing method. This method is specialized for quantum states that are fairly pure and they offer a significant performance improvement on large quantum systems. A low-density matrix can be estimated using fewer copies of the state and hence the sample complexity of the tomography decreases with the rank. Unknown low-rank states can also be reconstructed from an incomplete set of measurements using matrix completion techniques. This method is less resource expensive and more reliable recovery is possible based on the same type of randomly chosen measurements compared to full tomography.
