Quantum tomography for non-iid sources
Leonardo Zambrano
The paper proves that projected least‑squares quantum tomography retains optimal sample complexity even when the prepared states or channels are not independent and identically dis…
Fast quantum measurement tomography with optimal error bounds
Leonardo Zambrano, Sergi Ramos-Calderer, Richard Kueng
We present a two-step protocol for quantum measurement tomography that is light on classical co-processing cost and still achieves optimal sample complexity. Given measurement data…
Certifying quantum states without independence assumptions
Mariana Navarro, Leonardo Zambrano
Standard quantum verification and certification protocols often assume that experimental sources emit independent and identically distributed (i.i.d.) states. In realistic scenario…
Certifying ergotropy under partial information
Egle Pagliaro, Leonardo Zambrano, Mir Alimuddin +3
Ergotropy, the maximum work extractable from a quantum system, is a central resource in quantum physics. Computing ergotropy is well established when the system state is fully know…
Classical shadows for non-iid quantum sources
Leonardo Zambrano
Classical shadow tomography has emerged as a powerful framework for predicting properties of quantum many-body systems with favorable sample complexity. Standard theoretical guaran…
Certification of quantum properties with imperfect measurements
Leonardo Zambrano, Teodor Parella-Dilmé, Antonio AcÃn +1
The accurate characterization of quantum systems is essential for the advancement of quantum technologies. In particular, certifying convex functions of quantum states plays a cent…
