Tomographic Limits of the Petz Recovery Map

Peter Sidajaya, Clive Cenxin Aw, Mingxuan Liu +1

The Petz recovery map is considered one of the key candidates for the quantum analogue of Bayesian inference and Jeffrey's conditionalization. Since, there seems to be a natural co…

Proposal for creating spatial superposition of a large mass in a RF trap

Martine Schut, Jackson Tiong, Valerio Scarani

Engineering coherent spatial superpositions of levitated large masses is an ongoing challenge. Borrowing from recent experimental work, we consider a charged mass of hundreds of na…

Proper and improper mixed states serve as different prior beliefs for quantum state retrodiction

Mingxuan Liu, Valerio Scarani, Ge Bai

A mixed quantum state can be taken as capturing an unspecified form of ignorance; or as describing the lack of knowledge about the true pure state of the system ("proper mixture");…

Unifying Quantum Smoothing Theories with Extended Retrodiction

Mingxuan Liu, Ge Bai, Valerio Scarani

Estimating the state of an open quantum system monitored over time requires incorporating information from past measurements (filtering) and, for improved accuracy, also from futur…

Three sins against physics by an exaggerated quantum information perspective

Valerio Scarani

I point out three ways in which the perspective of quantum information may lead to distorted claims about physics: forgetting that light does not need to be quantised to show coher…

A Retrodictive Approach to Quantum State Smoothing

Mingxuan Liu, Valerio Scarani, Alexia Auffèves +1

Smoothing is a technique for estimating the state of an imperfectly monitored open system by combining both prior and posterior measurement information. In the quantum regime, curr…
