Learning Unitaries by Gradient Descent
Bobak Toussi Kiani, Seth Lloyd, Reevu Maity
We study the hardness of learning unitary transformations in via gradient descent on time parameters of alternating operator sequences. We provide numerical evidence that, d…
Quantum Boosting
Srinivasan Arunachalam, Reevu Maity
Suppose we have a weak learning algorithm for a Boolean-valued problem: produces hypotheses whose bias is small, only slightly better than random gu…
Efficient implementation of unitary transformations
Seth Lloyd, Reevu Maity
Quantum computation and quantum control operate by building unitary transformations out of sequences of elementary quantum logic operations or applications of control fields. This…
Detecting metrologically useful asymmetry and entanglement by a few local measurements
Chao Zhang, Benjamin Yadin, Zhi-Bo Hou +8
Important properties of a quantum system are not directly measurable, but they can be disclosed by how fast the system changes under controlled perturbations. In particular, asymme…
